Is possible for the bootloader to start the program if the W5100 (W5200, ...) shield is not present? Currently, the program does not start if the card is not present, and is not possible to upload the new program via the serial port.

I'm using an ATMega2560 and a W5500 shield. I can talk to the shield via web server and reset server, and I've configured everything on the EEPROM. But I can't get passed an infinite loop triggering a watchdog reset here. The socket is never opened and always returns "closed".

	do {
        // Write interrupt
		spiWriteReg(REG_S3_IR, S3_W_CB, 0xFF);
		// Write mode
		spiWriteReg(REG_S3_MR, S3_W_CB, MR_UDP);
		// Write TFTP Port
		spiWriteWord(REG_S3_PORT0, S3_W_CB, port);
		// Open Socket
		spiWriteReg(REG_S3_CR, S3_W_CB, CR_OPEN);
		while(spiReadReg(REG_S3_CR, S3_R_CB)) {
			//wait for command to complete
 		}
		// Read Status
		if(spiReadReg(REG_S3_SR, S3_R_CB) != SOCK_UDP)
			// Close Socket if it wasn't initialized correctly
			spiWriteReg(REG_S3_CR, S3_W_CB, CR_CLOSE);

		// If socket correctly opened continue
	} while(spiReadReg(REG_S3_SR, S3_R_CB) != SOCK_UDP);

Any ideas on getting past that?

Hi thanks for reading this, I know its been a while since a release, but this bootloader is so useful to me I hope its not just left in a sunset phase now.
I'm trying to use ariadne with its ethernet reset server alongside my sketch for some home automation equipment (saves massively and avoids laptops up ladders to update my controllers in odd locations). One of the tasks that does is send out a http POST to a remote home-assistant automation server with a JSON formatted string so it can keep the master house gui in sync with all the nodes.

When I enable reset.check in the main loop, the following code stops working

if (jsonclient.connect(Configuration.extJsonServer, Configuration.extJsonServerPort)) {
  // Make a HTTP JSON request:
  mylocalJsonData = (F("POST /api/states/switch."));
  Serial.print (F("inner loop json data is "));Serial.print (String(mylocalJsonData)+ "\n");
} else { Serial.print ("Error :- "+String(jsonclient)+ "\n");}

In the serial log I see this
" Error :- 0"
Error code zero indicating failed connection of course. And it also doesn't send the packets out the interface at all on tcpdump output.
My sketch has 2 other ethernet services which function fine, (udp for ntp client, and ethernet server listening on port 80 http use in my sketch which uses GET requests) so it seems its just the outbound POST from my arduino ethernet tcp as a client affected.

If I comment out reset.check(); in the main loop, the json POST starts working. It has to be a POST to authenticate to the remote server in the JSON headers.

I read a post from a few years ago from Stelios Tsampas where he was discussing how to work around a similar sounding issue, is it documented somewhere and this issue now solved?
http://developers.arduino.narkive.com/m4JMgDNs/remotely-resetting-an-arduino

As a workaround, I already have a authenticated section in my configuration web gui, can I call a reset method from that instead of running a whole daemon on a higher port with a check in the main loop just for the reset? I already have a function that calls the following to do a soft reset after updating network config in eeprom, I could just expand that out if so.
asm volatile (" jmp 0");

There are references to a 'hardware' folder which doesn't exist as well as the boards.txt and platform.txt not being inside the bootloaders folder and seemingly being unused.

The old codebndr version did have this 'hardware' folder and the boards.txt and platform.txt files were located inside in a completely different structure. I can get that version to install no problems in Arduino IDE and Atmel Studio 7. However I can't figure out a way to install this current structure with the given installation instructions.

Any pointers?

From @per1234 on May 8, 2015 1:59

I have created a working implementation of installation of Ariadne to the Arduino IDE via Boards Manager. The URL is:

https://per1234.github.io/Ariadne-Bootloader/package_codebendercc_ariadne-bootloader_index.json

This can be added to Arduino IDE 1.6.4 in File > Preferences > Additional Boards Manager URLs. Then Ariadne Bootloader will appear as one of the options for installation under Tools > Board > Boards Manager...

I would like to create a pull request to add this capability to Ariadne but first I need the installation file to be available. The most common way of doing this seems to be a Github release. My installation file is here:
https://github.com/per1234/Ariadne-Bootloader/releases/download/v1.0.0/ariadne.zip
You can download mine to use or create your own. If you create your own notice that the folder structure has to be changed slightly.

For examples of how others have set this up see:

Thanks, Per

Hi everyone.
I have built a modular board to test different combinations of ATmega and Wiznet .

Trying these combinations I have found an issue with TFTP transfers when trying to send the .bin to an ATmega1284P + WizNet5200 board. While it pings correctly, TFTP is timeout
This is the combination I would like to use, and the only one with this issue. which is not present when using other combinations of ATmega and WizNet. I've tried it successfully with the ATmega1284P + WixNet5100, or with the ATmega328 + Wiznet5200

I've tried with TFTP64 to discard windows TFTP client.
Any further ideas?

Hi,

I did first a upload of the bootloader of Ariadne on a Atmega2560 (in fact, a controllino Mega). I did some modifications in spi.h, spi.c for pinout on the eth et rtc (instead of sd).
(I uploaded with an arduinoISP with the http://www.gammon.com.au/forum/?id=11635 scketch)

I could make an upload through tftp and software was working fine but I got some issues to ping the atmega and to reupload through tftp. the device was unreachable... Also I got issue to upload the sketch on serial (via arduino IDE) with another computer (with mine it is still ok...?) : uploading is hanging...

then I tried with the Netload bootloader to check... There I can upload on serial. I can update the network data and I can ping the atmega... However I get a timeout when I try to upload through tftp (I disabled the firewall...)

any idea?

thanks !

Hello,

I try program this Ariadne-Bootloader to Arduino Mega2560 by ASIX PRESTO Programmer (I have only this programmer).

When I open hex file, there are some alert about Little or Big Endian:

Please help me with settings fuses. Is somewhere specify fuses for ariadne-bootloader?

I try default fuses with SPI prog. enabled, but it is not function ...

Many thanks,

Jan

Hi,

I couldn`t help but notice the bootloader is not protected by a WDT. I have a device on the field that from time to time hangs, and as I can see from logs writen on a SD card It does in the bootloader section. (it shows a "reboot" string on the log and then no "Power ON" string which is the very first thing it does on app start).

Ive changed the bootloader code to include proper wdt protection, but Im unable to compile it... It may sound like a noob error, but it fails on the memcpy_PF... I`ve seen previous ppl having this error but no solution to it.

I do compile on windows, using the WinAVR toolchain.

Where should I change on the makefile so I can compile it? Tried everywhere and still got this error.

Note that I would gladly post the wdt fix once I`ve tested.

Hello, I use your ariadne bootloader with arduino mega 2560 and standard ethernet shield W5100. Now I have problem with upload this project. When I upload by USB cable standard from arduino IDE, it´s ok and function, but by TFTP it is not function - TFTP confirm transmission as success, but after uploads there is only LED still flashing. Smaller project is no problem upload by TFTP an your ariadne bootloader. Do you have some ideas why ?

There is some screenshot and bin and ino files:

Hi,

I have a Arduino UNO (Arduino as ISP) , a Arduino MEGA2560 (to be programmed with Ariadne bootloader) and W5100 Ethernet shield.

As you have mentioned, I've followed the below link to program the Mega board with Ariadne-Bootloader(.h) using UNO(Arduino as ISP).
http://www.gammon.com.au/forum/?id=11635

Able to program the default Mega bootloader code using gammon's url.

I have converted "ariadne_atmega2560_w5100.hex" bootloader hex file to "ariadne_atmega2560_w5100.h" using MUSHClient and flashed the code into Mega2560 board.

Now I have tried to upload the blink code using USB cable (as usual) but I have got the below error.

Can you please help me on this issue ?

Library TFTP wrong use registers REG_S3_RX_RD0, REG_S3_TX_WR0, REG_S3_RX_RSR0.

Trying to modify AriadneBootloader for W5200 and ATmega2560 with progaram> 64KB noticed that the transmission every time it stops at 55KB for the 2K buffer soket.

Analyzed the library and documentation W5100 and W5200.

REG_S3_TX_WR0 is NO PHYSICAL ADDRESS for the third soket and can not be freely modified. Is the number of bytes processed the program. A REG_S3_RX_RSR0 tells you how many bytes have to be read in the buffer.

In a few days try shared corrected code. For now, I have to very modified system and W5200. In the meantime, put 'suggested amendments.

Today I have only smartphone.

When soket is initialized:
spiWriteWord (REG_S3_RX_RD0, 0);

You can not move REG_S3_RX_RD0 of S3_RX_START:
-- If (readPointer == 0) readPointer = S3_RX_START;

or move back
-- If (readPointer == S3_RX_END) readPointer = S3_RX_START;
repleace with like this
++ if ((--packetSize) == 0)break;//end of package
or better
-- for(count = TFTP_PACKET_MAX_SIZE; count--;) {
++ for(count = packetSize; count--;) {

to read the bytes from the physical address, use the mask and shift:

-- SpiWriteWord (REG_S3_RX_RD0, readPointer);
++ SpiWriteWord (REG_S3_RX_RD0, S3_RX_START + (readPointer & 0x7ff));

0x7ff - mask for 2k

And of course analogous not to REG_S3_TX_WR0:

-- writePointer = spiReadWord (REG_S3_TX_WR0 - S3_TX_START);
++ writePointer = spiReadWord (REG_S3_TX_RD0);

-- If (writePointer == S3_TX_END) writePointer = S3_TX_START;
-- SpiWriteWord (REG_S3_TX_WR0, writePointer - S3_TX_START);
++ SpiWriteWord (REG_S3_TX_WR0, S3_TX_START + (writePointer & 0x7ff));

And now at last
uint16_t PacketSize = spiReadWord (REG_S3_RX_RSR0);
contains useful information how much data is left in the buffer.

You can probably remove.

while ((spiReadReg (REG_S3_IR) & IR_RECV)) {
spiWriteReg (REG_S3_IR, IR_RECV);
/ / FIXME: is this right after all? smaller delay but
/ / Still a delay and it still breaks occasionally
delayms (TFTP_PACKET_DELAY);
}

Besides, I've used yet PacketSize I used to check whether the data came in full.

I not use this for W5100 only W5200 and 4K socket.

Sorry for my English, I used a translator.

Dear All,

I've flashed the ariadne bootloader code into Arduino UNO + Ethernet shield.
Also able to flash the code via USB interface as usal.
But not able to flash via TFTP.

I'd setup the ethernet cable between Linux PC to Arduino UNO+Shield, and able to see the activity on ethernet port LEDs.
And I set up address for PC as 192.168.1.125 and default IP address for Arduino UNO+Shield 192.168.1.128
Not able to ping the IP address 192.168.1.128 from PC and thus got TFTP timedout error when I tried to transfer the binary files. Tried using Linux and Windows PCs

Can anyone please help me on this problem ?

Regards,
Titus S.

the code below seem wrong to me.
ARIADNE_SIGPOS which is the same as EEPROM_IMG_STAT from neteeprom.h, use as status, if the image uploaded by the booloader is OK or not.

While in the below code, it look like it is used as if the ARIADNE boolader itself is been used... in the system, and if not use all the EEPROM (start from offset 0).

byw: the ARIADNE_OFFSET also seem not right. in neteeprom.h, last used eeprom address is 63.

NewEEPROM.h:

#define ARIADNE_SIGPOS (0x02)
#define ARIADNE_SIGVAL (0xEE)
#define ARIADNE_OFFSET (0x40)
#define NO_OFFSET      (0x00)

NewEEPROM.cpp:

NewEEPROMClass::NewEEPROMClass(void)
{
	if(read(ARIADNE_SIGPOS, 0) == ARIADNE_SIGVAL) _offset = ARIADNE_OFFSET;
	else _offset = NO_OFFSET;
}

I'm getting endless reset after watchdog resets arduino (in the sketch I set it to 8sec as sketch is too big and it gets hangups time to time), and it does not stop even if I press reset button, only if I reflash the sketch. Is thwere any solution for that?

** Sorry in advance for the code blocks with no newlines, I can't seem to get them formatted properly..? **

Hey there,
First off, everyone who has worked with this in the past, big Thanks! :) Also to loathingKernel for your wonderful continuation!

I'm having a look at this bootloader as I would like to use it for programming a couple of units in a remote location.. Which this bootloader should be able to do, which is great :)

However, I'm having a few problems.

Which software are you using for editing and uploading the bootloader to the target?

• I've tried Arduino 1.8.3 which seems to be a no go. I've tried to put the "hardware" and "libraries" both under /arduino/ and also in the /arduino path, but also in the "C:/program.../arduino" path but I just get errors that the board.txt file can't be read and similar. I can of course provide more errors when I'm told exactly where the files should be put, but as of right now, when I follow the Readme file, it just doesn't work.

• I've also tried Atmel Studio 7 which can compile the code, create an HEX file and upload it to the target. However, I still can't ping the device either on the default IP which ends in .128 or the IP I've set which should be .33

I've edited the net.h file with my network settings, like the following;
/ Network settings /
#define IP_ADDR 192,168,1,33
#define SUB_MASK 255,255,255,0
#define GW_ADDR 192,168,1,1
#define MAC_ADDR 0x55,0xD7,0x53,0x00,0x01,0x0B

But, I can't ping the device on this address. The Gateway address I suppose should be the real network gateway, such as the router, correct?

Also, how do I enable debugging in the source code, so that it outputs data to the Serial port, just like the "ariadne_debug2560_w5100.hex" file does when it is uploaded?

When I upload the bootloader file "ariadne_debug2560_w5100.hex" I do get debug output and the IP address is set to 192.168.1.128 - which by the way is matching my network and it is a free IP. I still can't ping the device though.

The device I'm using is actually an Controllino Maxi. This device is based off the Atmega2560 with a WizNet 5100 chip. The following are the pin connections which is hardwired and can't be changed in any way.

Arduino 52 / PB1 - WizNet SCK
Arduino 51 / PB2 - WizNet MOSI
Arduino 50 / PB3 - WizNet MISO
Arduino xx / PJ3 - WizNet SS/CS

I've thought that maybe the PJ3 should be configured in the spi.h file as the chipselect, but not sure if that does anything? I've tried changing both #define SS and #define ETH_SS to PINJ3, but no change in response from the unit on the network.

Something I've noticed is that the PINB7, defined as LED in spi.h, the led is not flashing or blinking, just solid on.

Also, I don't see any traffic on WireShark that could be the bootloader. But I guess thats only when inbound traffic is active. The bootloader isn't transmitting anything without an incomming call, right?

Pinout for the Controllino, Ethernet chip just right of center on the pinout sheet, below SD card connector..
http://controllino.biz/wp-content/uploads/2017/05/CONTROLLINO-MAXI-Pinout.pdf

I think that is all for the moment, would it possible to help me out in any way? :)

Edit..
If I run the debug version of the hex file "ariadne_debug2560_w5100.hex" available within the Git download I get the following output on the serial line;

Greetings;

I don't know how to contact the author to ask a question:

Before I go flashing stuff, will this bootloader still work the regular way on my ArduinoIDE, so I can work on a duplicate board to finetune my programs?

Cheers;

Hello,

I am trying to reset my device using the watchdog to enter the bootloader, the device resets, however, after the reset, the appication code is loaded, instead of the bootloader.
As per Atmel datasheet, if BOOTRST is programmed, then the code loaded after both WDT reset and external reset should be the bootloader.

When I set the reset pin to low instead of doing a WDT reset, then the bootloader is loaded before the application.

I have loaded the bootloader properly and the BOOTRST fuse is programmed, see the output below

And this is the code I am using to trigger a WDT reset:

NetEEPROM.writeImgBad();
wdt_disable();
wdt_enable(WDTO_120MS);
while(1);

Thanks for your help

Hello!

There was a problem with the firmware over the network through NAT. The TFTP server generates random ports during data transfer and there is no way to forward them. Is it possible to make a port permanent?

From @loathingKernel on November 6, 2012 12:59

Since most ethernet shields have an SD card socket this might would be useful to have.
I am just leaving it here to see how many people are interested in having this feature integrated to
Ariadne.

It has been done before so, probably, i will be using the existing solution if it fits nicely with the rest of the code.

EEPROM.put and get requests does not work with newEEPROM library, can anyone fix it? or suggest the way forward...

Copied from original issue: codebndr#38

I managed to get this bootloader installed but the reset server example sketch does not seem to work. I get no webpage served on port 80 (by typing in just the IP in the browser) which according to the sketch should serve sensor values.

The reset servers seems to respond at IP:8080/password/reset and I can then upload a sketch. So at least part of it works.

Also, how would I go about including the reset server function in a normal sketch? Do I need to include all the code in the ResetServer example (all #includes and the reset.check() in the main loop)?

Eventually I'd like to use an external watchdog timer to perform resets as well. Is this compatible with the bootloader?

On a seperate note, uploading a sketch.bin of the same name does not seem to work. e.g. if the server is running blink.bin, I cannot simply change the blink frequency in the code, recompile and upload with "tftp> put blink.bin"

If I rename blink.bin to blink5.bin and use "put blink5.bin" the code is accepted by the bootloader.

README.md says:

Now to actually upload the binary file all you have to do is reset the board and in the next 5 seconds run the following command.

but the bootloader timeout is actually 20 seconds. Was it intentional to make the bootloader timeout so long? 20 seconds seems a bit longer than necessary.

Hi, I have mega2560 + W5100 ethernet shield.
And I testing some sketches for personal project.
After I burning your bootloader throug Arduino ISP my mega+w5100 cant connetct to my network.
I'v setted correct IP and gateway trugh WriteNetworkSettings sketch, and verifing it with ReadNetworkSettings .
There is the output of this sketch

(all is correct, 192.168.31.1 is my gateway(router))

there is testing sketch that also dont want to connect to lan

How can I fix problem or restore previous condition of mega and w5100 ? Thank you, sory for my english

P.S.
I'v tried connect my w5100 to another board, arduino uno with same scetch. And that not work to, send me same "Failed to configure Ethernet using DHCP".

From @DarkSector on July 11, 2015 19:41

Can we get support for ENC28J60 ethernet chip? This project is a very cool way to push sketches. How can we use it on 28j60 instead of W5100?

Hello, so I am able to burn the bootloader and upload the "ReadNetworkSettings" sketch using Serial USB Comm.

I am also able to ping the default IP when the Arduino is powered and connected (192.168.1.128)

Then I tried to upload the sample "blink" ( utilities\tests\blink\atmega328_blink9.bin ) by resetting the Arduino Board (LED13 now blinks quickly), then type "tftp -i 192.168.1.128 PUT atmega328_blink9.bin" (I already cd'd to the folder). After some times, it says "Connect request failed".

Previously, after uploading the sample "ReadNetworkSetting", the Arduino will be able to run the sketch after about 10 seconds after reset (the upload period).

But if I did attempt to TFTP the sketch (atmega328_blink9.bin), my Arduino is now not able to load the previous sketch and will keep blinking quickly (even after resetting, and waiting for 10 seconds). The previously uploaded sketch is now gone, but I am still able to upload sketches via serial. What should I do?.. (Windows 10 64bit, Arduino 1.6.7)
