mysensorsbootloaderrf24's Issues

bootloader from development branch on arduino nano

I've burned the 16Mhz bootload onto my nano. No Sketch burned onto it.
NRF24 is connected to that nano.

In mysyscontroller, i can not see this node, to provide it with an firmware.
What can i do?

Update makefile and instructions

MYSBootloader_8MHz.hex FOTO does not work

Hi,

When flash the MYSBootloader_8MHz.hex 328p it does not communicate the OTA support request??

It seems not working, or what else good be wrong. Normal flashing serial works well.

Add Config Option for CE7 and CSN10

Electrodragons device needs this Configuration.

PS: i have already made them. How to push it to the development brunch?

Question: What are correct boards.txt info/fuses for 1mhz version?

Hi, I guess it is not yet ready, but maybe it is a "quick&easy" for someone to post correct content of boards.txt for 1mhz (3.3v) version of bootloader?
Thanks

Endless loop

When I reboot a node with mysbootloader the node never goes up again. The node is in a loop of endless restart.

Hardware where I observed this:
Arduino Pro Mini 5v (16 Mhz)
My simple board with atmega328P with internal oscilator 8 Mhz and 5V power
nrf24l01

Software:

• Mysbootloader - 8 Mhz taken from repository with revision 7c4f3c3
• Mysensors library ver. 2.3.0
• Fuses for internal oscillator:
  proMYSBL8VRC1.bootloader.low_fuses=0xE2
  proMYSBL8VRC1.bootloader.high_fuses=0xDA
  proMYSBL8VRC1.bootloader.extended_fuses=0x06
  proMYSBL8VRC1.bootloader.unlock_bits=0x3F
  proMYSBL8VRC1.bootloader.lock_bits=0x0F

Steps to reproduce:

1. Burn a mysbootloader by using usbasp
2. Upload an easy sketch also by using usbasp
3. When the node is ready and sketch is working use mycontroller or myscontroller (whatever) and send I_REBOOT command to the node.
4. When the command gets the node, then node dies. It looks like it is doing something for a tiny part of second and after that is rebooted. It is necessary to unplug the node and plug again to make it up.

There is also impossible to perform any OTA update as it simply does not work. I tested it also on very elementary sketch which did nothing more than send a counter to the controller with the same result.

My observations:
Finally I found workaround and procedure how I could make my nodes working with OTA/mysbootloader. I guess that the problem was that I uploaded a first sketch by using usbasp instead of OTA. When I burned bootloader without sketch I was able to work with OTA, update software and reboot nodes.

I just report it to you as I believe that you deserve this because you have done great job which is useful for many people. If you manage to fix this problem it would be wonderful. If not I would suggest to write some information to warn other people from repeating my mistake. I really spent a few days experimenting with this to get to this conclusions.

No firmware download start, when trying to save the battery

Hi, love your MYSbootloader/Controller effort,

My sensors reports every 2 minutes, using "smartSleep", marked it as running on battery, and I can indeed download new firmware, great. I see my data and a heartbeat in MYScontroller every 2 minutes

This works very good (but only after adding the famous both 0.1 and 10 uF capacitors to the NRF)

But the "smartSleep" adds 0.5 second radio/MCU on time and that is killing the battery :
(0.5 sec * 20mA * 30 times per hour /3600)24365 = 730mAh right ?
So if I am correct, that .5 second every 2 minutes alone will empty an AA battery in 1 year

So as alternative :
I report every 2 minutes and then a "sleep", but every 30 times = 1 hour, I throw in a "smartSleep" and not a "sleep". I see my data every 2 minutes and I see a heartbeat every 30 times = 1 hour

I don't mind if it can take 1 hour, but I don't want to manually reset/power cycle, as the sensors are on difficult places so battery exchange and reset should be limited :-)

Problem :
But when I request a firmware download, it does not start on the "smartSleep"/heartbeat
Perhaps you ignore the firmware download when you have seen a "sleep" or it takes too long or ??
I did not manage to find the source of the MYSController, did you make that available ?

In a test I lowered the sleep time to 10 seconds, so 5 minutes for a heartbeat , same problem.

Reset and power cycle do start a download, so no major issues there.

Can you change is so that it will start the download on any first "smartSleep" for below ( battery saving script)? Lets say even if 24 hours :-)

void loop()
{
BatteryVoltage = readVcc() * BatteryCorrection ; // readVcc returns a long type
send(msgBatt.set (BatteryVoltage, 2));
if (count == 0)
{
smartSleep(SleepTime);
}
else
{
sleep(SleepTime);
}
count = (count + 1) % 30;
}

Makefile compatibility

Hi,

source cannot be compiled when arduino installed in a folder something like: "E:/Program Files x86)/Arduino" Problem is easy to solve.

Proposal from my side to change on line in the MAKEFILE.
Change:
"$(BINPATH)avr-gcc" $(CFLAGS) -I$(INCLUDES) $< -o $@
to:
"$(BINPATH)avr-gcc" $(CFLAGS) -I"$(INCLUDES)" $< -o $@

Please not the two extra quotes before and after $INCLUDES. As it is in case of BINPATH. Then no more compiling error when arduino is installed in a folder like Program Files (x86).

Thank you!

hex file for other frequencies

Hello,
Would you be able to publish ex files for 8Mhz and 1Mhz? Especially the 1Mhz as it is the frequency most used for battery devices. Thanks

Compiling the bootloader - Not bootloader working beside the precompiled ones

Hello,

I have tried to compile your source by using the make file.

No matter what i tried i can't get a bootloader that i compiled myself to work correctly. Only those precompiled that you publish work.
The bootloader is usually too big , it goes beyond address 8000 , I notice that the make file puts the bootloader at 0x7800.
-section-start=.text=0x7800

More information:
-Win 10
-using AVRWIN ( paths are correct in the make file)

The make result :
$ make rm *.o rm *.elf rm *.hex "C:/WinAVR-20100110/bin/avr-gcc" -funsigned-char -funsigned-bitfields -DF_CPU=16000000L -Os -ffunction-sections -fdata-sections -fpack-struct -fshort-enums -mrelax -Wall -Wextra -Wundef -pedantic -mmcu=atmega328p -c -std=gnu99 -MD -MP -MF "MYSBootloader.d" -MT"MYSBootloader.d" -MT"MYSBootloader.o" -IC:/WinAVR-20100110/avr/include/avr/ MYSBootloader.c -o MYSBootloader.o

If helping me compile this isn't easy, but you could somehow compile a bootloader for me with adding two lines :

DDRD |= 0x80; PORTD |= 0x80;

after line 100 in MYSbootloader.c.

Thank you for your time

Update defines to match MySensors library?

Should this repo be updated to match the defines used by the MySensors 2.x library?
Example: RF24_DATARATE -> MY_RF24_DATARATE

MySensorsBootloader causes linker stack smashing on recent gcc versions

Trying to compile this bootloader with gcc shipped with debian stable (bullseye) or debian testing results in a stack smashing during linking.

development version hex file is not working properly

@tekka007 I tried development version hex file 8MHz from https://github.com/mysensors/MySensorsBootloaderRF24/tree/development/hex it did not work as expected. I noticed firmware request is too slow from node. I guess recent chnages has some huge performance issue. I tested with MyController.org. I do not have windows environment to test with MYSController.

I using 8MHz file from https://forum.mysensors.org/topic/4991/mysbootloader-1-3pre2-testing Which is working awesome and quick response from node.

compiling for CE pin 7, CSN pin 8

Hi,

I'm migrating from RF24Network to MySensors. My config used to be CE7, CSN8. I'm trying to build the bootloader for this configuration, but I can't get it to work.
Using a new node with the default pin config of CE9, CSN10 does work, but I'd prefer not to rewire my existing nodes if I can help it.

I added a new define to MYSbootloader.c and the following code to HW.h:

#elif defined(SPI_PINS_CE7_CSN8)
#define CE_PORT PORTD // port for CE
#define CE_DDR DDRD // DDR for CE
#define CE_PIN PD7 // Arduino Pin 7 <-> Bit 7 of port D

#define CSN_PORT	PORTB	// port for CSN
#define CSN_DDR		DDRB	// DDR for CSN
#define	CSN_PIN		PB0		// Arduino Pin  8 <-> Bit 2 of port B

#endif

...

#elif defined(SPI_PINS_CE7_CSN8)
	// PB0 is SS pin has to be defined as OUTPUT, else SPI goes to slave mode
	SPI_DDR = _BV(SPI_MOSI) | _BV(SPI_SCLK) | _BV(PB0) | _BV(CSN_PIN);
	CE_DDR = _BV(CE_PIN);
#endif

based on what I found for the existing defines. It's the last part I'm not sure about. Could anyone help me out?
Thanks!

Running on 8 MHz internal clock

Hi,
is it possible to create the version suitable for m328 running on internal 8 MHz oscillator? Thank a lot

Not working

Hi. I have tried the hex file for 328p 16mhz. When i power on i se an ID request on the gateway, but doesnt register with the Controller. When i use the MYSBootloader included with the latest MYSController the node registers and OTA works just fine. I use mycontroller.org and RasPI as gateway. Anyone got this bootloader working? Or can give me some tips on getting it to work?

Running the OTA will kill the node ID and will not complete

I use the latest pre-compiled hex from "compiled" folder with jkandasa MyController.org.
First OTA update went well.
But subsequent updates issue the BL_CMD_CLEAR_EEPROM command, which destroys NODE_ID and PARENT_NODE_ID.

MySensorsBootloaderRF24/MySensorsBootloader.h

Line 252 in 335f9bd

for(uint16_t i = 0; i < EEPROM_SIZE; i++) eeprom_update_byte((uint8_t *)i, EEPROM_ERASED_BYTE);

As a result, the controller loses the device and cannot send firmware to it.

In my case, it's even worse, because I have 100 identical devices on the network with the same firmware, which I only distinguish by NODE_ID.
That is, if I push firmware to all devices, my system/network will be destroyed, and it may take several days to restore it - I will have to manually restore NODE_ID on each device.

It's OK, if I change this like to

for(uint16_t i = EEPROM_DISTANCE_ADDRESS; i < EEPROM_SIZE; i++)
    eeprom_update_byte((uint8_t *)i, EEPROM_ERASED_BYTE);

or I should erase EEPROM_FIRMWARE_xxxxx only?

Tired lastest hex files, verification error

Just downloaded the latest files from dev branch.
Copied boards from here.
When i try to upload any mysensorsBootloader i get:
avrdude: verification error, first mismatch at byte 0x7800
0x00 != 0x11
avrdude: verification error; content mismatch

Flash init error

I have freshly created pro mini 3.3 8 MHz.
I flashed MySbootloader (developer branch) and when I try on OTA update I always get:
!OTA:FWP:FLASH INIT FAIL

Why would firmware-less node proceed to startup after MAX_FIRMWARE_REQUEST_RESEND reached?

Hi @tekka007,

I was wondering why a node that I left last night without firmware stopped asking for it(firmware), this morning.
I read the code and found what's causing it.
Is this the intended behavior?

Wouldn't be nicer to have the node requesting firmware perpetually until firmware submitted?

Now, that node is in limbo state, without firmware, and there is no other way to restore communication with it, than with a hardware reset.

Let me know what you think, i can contribute with coding.

Regards.

FW update problem with ESP8266 gateway

I have problem with FW update via MYSController, node just rebooting and thats all - no code update

How to change time while bootloader is looking for new firmware?

Hi,

1st - great work. Love it.

Just wondering how I can minimize the boot time, while its looking for a new firmware?

Regards
Joerg

Bootloader entered in to infinite loop.

When we do not have any node/gateway around the reachable area, bootloader gets stuck on searching something. I guess it's waiting for parent node id?

In this situation bootloader never enter into the application/user program.

I use 1.3.0-beta.3 bootloader.

OTA infinit loop

in some times, the bootloader keeps request a firmware request and aparently dont listen the response from gateway.

Compiling for different channels

Hi
I'm trying to compile hex files for channels different from the default one.
I'm using MySBootloader dev branch and the provided boards.txt

I changed the channel here and the board frequency to 8MHz here.

I then compiled (simply running a Make), no errors, but when I flash the obtained hex file on my Arduino (Pro Mini 3.3V 8MHz) it hangs and I'm not able to upload any sketch.

Thanks in advance for any help or suggestion
