Hey,
I have a problem flashing the .hex file to the other Arduino Uno.
Every time I try to flash the .hex file I get this error:
avrdude: ERROR: address 0x8010 out of range at line 129 of /home/marcel/Downloads/.arduino-1.6.5-r5/hardware/arduino/avr/bootloaders/atmega/2boots-arduino-atmega328p-16000000L-PD4.hex
avrdude: read from file '/home/marcel/Downloads/.arduino-1.6.5-r5/hardware/arduino/avr/bootloaders/atmega/2boots-arduino-atmega328p-16000000L-PD4.hex' failed
I dont know why this happen.
Can someone please help me?
Thanks

Hello

I am trying to port 2boots for Mega2560 and having some hard times ... :)

However I noticed this line in stk500v1:
line47: #if !defined(AVR_ATmega168) || !defined(AVR_ATmega328P)

Am I wrong to believe this is never false but always true ?
It seems that the test can be false only if both are defined which is impossible.

Best regards

Any update this code to work with the Arduino DUE ?
Thank you for reply

Of course thanks so much for your work on this, it's a hugely useful feature.

I'm in the process of adding basic support for SDHC cards, which seem to be all that is available these days.
I have a working version based off the code at https://github.com/mharizanov/uIoT which is an old copy of this repo, and, with some code shuffling, it just squeeks in under 2K. Before my changes, that version compiles to 2006 bytes.

Now, I've forked this project, with the intention of making my changes on the latest code, however, before I even start, I can't get it compiled under 2K - I'm getting 2218 bytes.
This is all under the same environment etc (OS X), and I can't see that much has changed other than adding 1280 support (which is in an #ifdef).

There also doesn't appear to be any test that the code size matches the allocated boot size, so it's something to constantly watch.

Any tips what might be bloating my compile of the latest version?

Hi does 2boots work with arduino ide? it tryes to work the rx led flashes 3 times when i try to upload sketch to my arduino uno,ive tryed a few ide new and old,i thought it was supposed to work with arduino as well as having the mmc sd card upload option.stk500 not in sync is the error it gives.
Thanks

What about SAMD21/Arduino Zero support? Or does anyone know of a bootloader for this controller which can flash a new sketch via sd-card?

Hello. Did you know about the project virtmem, could they run larger apps?

Hi Thomas,
i look very interesting of your bootloader but i see you have a todo for the ATMega 2560.
I want to use the Bootloader for a ATMega 2560 what is the todo for the 2560?
Is it only the Pin settings for the SD Card or another stuff todo?

Thanks for make your project public!

Any plans to update this code to work with the Leonardo and other 32U4 boards?

• only one boot (SD Card)
• needs 4 kb
• but supports FAT32

Hi,

first the bootloader is working fine. I have made some minor changes, because i need some LEDs for the visual feedback. It runs on a atmega 328 with 16MHz.
But i have serious problems with the bootloader, when there is a FAT32 formatted card inserted. The bootloader stops working and nothing more happens. It doesn't have to work with a FAT32 card, but i'm expecting that the bootloader start the normal program (which itself can handle a FAT32 card). Could you help me?

i literally spent 3 hours to find how to get avr-gcc lower than 4.6 but i couldnt find it. Can you please lead me to how to install it on ubuntu 18.04? Thanks
