Problems burning SAMD boards with a programmer

ninora · April 12, 2020, 1:57pm

Hello!

I am using the Adafruit_DAP "flash_from_SD" example to burn MKR bootloader using another MKR with ETH shield as a programmer, hooked to target's SWD pads. It works well every time, however, using the same method to burn a sketch is not successful.

The sketch is something I wrote and saved as a bin file using IDE, so no bootloader here, and I know my bin is good as I use it to update the board Over The Air which also works well.

Is there a difference between burning a bootloader vs. other programs, for instance, are they burned to the same Flash address (normally 0 I assume), maybe something else?

Thanks!

What do you mean by "is not successful"? If you're getting an error message, please post the full text of it.

No error message, the burning completed as expected, it is just the board that bricks after the matter (reflashing the bootloader brings it back alive).

is the bin build for start address without bootloader? in SAMD the execution starts at address 0. the bootloader is there usually. the DAP erases the flash. so if your bin starts at address 2000 and is flashed at address 0, it will not work

No, I guess I should change the linker script in boards.txt file or there's a more direct approach?

why did you put it in arduino/avr folder?

Arduino IDE and Arduino builder support custom board definitions from [hardware subfolder](https://arduino.github.io/arduino-cli/platform-specification/) of your sketches folder. These definitions can use core classes and tools from installed board packages.

This GitHub repository contains my settings for boards I use for my project and to develop Arduino libraries. You can use it as starting point for your boards specialties.

![folders](my_boards.png)

All boards in this repo are only additions to installed 'official' board packages. My files contain only definition of the board in boards.txt, the folder in variants and platform.txt file contains only additional entries. The file programmers.txt contains sample definitions of 'programmer' entries for OTA upload without the IDE detecting the network port.

## Boards

### AVR architecture

Boards defined here use build of [Optiboot bootloader with `copy_flash_pages` function](https://github.com/Optiboot/optiboot/pull/269) (for ArduinoOTA library). platform.txt contains entries for sketch upload over network to ArduinoOTA library. All boards refer official Arduino AVR core and tools.

The official Arduino Mega doesn't use Optiboot bootloader. It has a 4 kB bootloader. The board definition here is changed to respect 1 kB Optiboot bootloader. The AVR package can use arduino:mega as variant reference to official package, so the variants folder doesn't need to be copied here. 

I have [a small series ATmega1284p board](https://github.com/budvar10/Arduino-ATmega1284P) by budvar10. It has perfect Uno pins compatibility. The pin mapping in variants is copied from budvar10's repo.

### SAMD architecture

Embarrassing
Thanks

Based on the good advices here I was able to burn a bootloader and afterwards use Serial to upload a sketch, which works, I can also burn a Blink bin compiled for address 0, works as well.

However, when I try to burn a bootloader and afterwards burn a Blink bin compiled with default address 2000, the board bricks.

You may ask why burn a BL and then burn the program when I can use Serial in the first place?

Because the target is to burn the program without a bootloader, and where Blinks works well off address 0, I am having troubles running more complex programs with communication libraries straight off address 0, it simply won't run and I am trying to isolate the cause.

I run my 100 kB bin with Ethernet and SD card without problems from address 0.

without problems from address 0.

Mine too! After fixing a typo in the boards file...
As always thanks a lot.
