I'm using nRF Connect SDK v2.2.0 and the central_bas sample project with MCUBoot in serial recovery to implement a firmware update functionality for a custom board. I got it to run on my board and got output via UART. Also mcumgr commands like "image list" were working fine.
Yesterday I came back into office after a break and everytime I send "image list" to my board, I get an NMP timeout.
Now I tried the sample project on an nRF5340DK but I got the same result. If I change my configuration so that mcumgr works via UART (CONFIG_MCUMGR=y and CONFIG_MCUMGR_SMP_UART=y) it works perfectly fine. The used connection string for mcumgr is:
mcumgr conn add nrf53 type="serial" connstring="dev=COM5,baud=115200,mtu=512" mcumgr -c nrf53 image list
Was there an update to the SDK or nRF Connect for VS Code that broke some functionality? Can anyone reproduce this issue?
Best regards,
Alex
