Hi,
Does anyone have suggestions on how to get a board out of bootloader mode beyond just the reset button?
I have a feather that I have been using for the last couple months with very few issues. A couple days ago after uploading some code to the board, I got no response in the serial terminal after pressing the reset button.
After much debugging it appears the board is stuck in bootloader mode (I can’t verify with the blue led since I had to remove it due to a previous issue of it not turning off - even though it would exit bootloader mode). A few notes on it.
- I’ll disconnect all power to the board
- When I try plug it back in I can run the zephyr-tools
newtmgr -c .... upload command and it will successfully upload to the board (no need to put it into bootloader)
- I have tried 5 different applications, including many of the basic sample applications
- Even after uploading the AT Client and disconnecting and reconnecting the board to the serial, it won’t display any output
- I have uploaded a program that I know connects to the hologram network automatically. After uploading the code and resetting the device, it doesn’t show up as connected in the hologram dashboard (e.g. the code doesn’t run).
Unfortunately I have no blue led anymore to test a simple blinky application. Mentioned in a previous post, but the blue LED wouldn’t turn off even though it would still exit bootloader mode (not sure if it’s related).
We have about 5 of these boards across our developers and they haven’t found any issues with our test code or device overlays. Might just a specific board issue.
