Impossible to flash qf_bootloader.bin
Posted: Thu Mar 11, 2021 5:51 pm
Hi,
As my green led was not breathing I followed the step of this video to "unbrick" my board.

Once the qf_loadflash.bin is being run my green led is breathing but once I disconnect the J-link, remove the jumpers J1 and J7 and unplug then plug the board, when I press the usr button while the blue led is flashing my green Led is not breathing (it just stays green) as if the board is still bricked. And I can't flash any .bin in the board while it this state.
Therefore I tried to follow this tutorial :
viewtopic.php?f=4&t=29
So i tried to flash the bootloader with the jumpers and the J-link still connected and the green led breathing but I got the same result.
Here is what I get when I try to flash the bootloader, it just stays like that forever :
qfprog --port /dev/ttyACM0 --bootloader qf_bootloader.bin --mode m4
CLI mode
ports = ['/dev/ttyACM0 (QuickFeather)'] 1
Using port /dev/ttyACM0 (QuickFeather)
Programming bootloader with qf_bootloader.bin
Erasing designated flash pages
Erase 32.0 KiB ( 0x52 ) at 0x0
I'm not sure of what I'm doing wrong so if anyone have a clue please let me know.
Best regards
