Trouble Compiling MCUboot with USB Stack

Hello

I don't have a XIA board to test with, unfortunately. Could you try the USB ACM sample in Zephyr to see if the port appears then?

Hello Vidar,

Thank you for your reply. Indeed, if I add "CONFIG_MULTITHREADING=y" in my MCUboot overlay, the blinky project compiles well :)

Unfortunately, the xiao_ble is not recognized on my laptop (ubuntu 22.04), I don't see the LED blinking by the way. I pushed the reset button multiple times, but no effect.

I'm using tio to monitor the serial port. When I'm using the command to list all available serial devices, I get nothing.

I suspect that the xiao is crashing in loop. Do you have any clue ? I have replaced the original bootloader which was Adafruit bootloader by MCUboot, is it possible that the reset button is not functional now ?

Hello Robin,

To use the USB stack in MCUBoot, you must enable multithreading support. Add 'CONFIG_MULTITHREADING=y' to your MCUBoot overlay in: blinky_dfu_ota_bt_v1/blinky/child_image/mcuboot.conf to enable it.

Kind regards,

Vidar
