Bootloader Size #204

Closed Sorunome closed 7 years ago

Sorunome commented 7 years ago

Hey, I tried making a custom bootloader for the arduino zero with a different size, though.

I updated the size in https://github.com/arduino/ArduinoCore-samd/blob/master/bootloaders/zero/bootloader_samd21x18.ld#L29 and https://github.com/arduino/ArduinoCore-samd/blob/master/platform.txt#L155 and https://github.com/arduino/ArduinoCore-samd/blob/master/variants/arduino_zero/linker_scripts/gcc/flash_with_bootloader.ld#L28

When uploading via Programming Port everything seems to be working fine, however when uploading via Native Port BOSSA still issues chipErase(addr=0x2000) and writeBuffer(scr_addr=0x20005000, dst_addr=0x2000, size=0x1000) (The new bootloader size is 0x4000)

Here's the full output, in hope somebody could help me:

Any help would be greatly appreciated!

Hi @Sorunome , the issue is already in the todo list on bossac repo https://github.com/shumatech/BOSSA/issues/33 . Feel free to comment there to speedup the process :slightly_smiling_face: Thanks!
