For the working one, I can enter commands through cutecom, and ifconfig ecm0 responds correctly
Otherwise, with the other I cannot enter any command
just this line loop:
swi-mdm9x28-wp user.err kernel: [49.040354] wait\_for\_irsc\_completion: waiting for IPC Security Conf.
Like the boot steps are not finished and give me no access to the board

Suggest you downgrade to fw R9, and then use “swiflash -m wp77xx -r” to erase user app partition.
Please see here

> First of all, the command should be “swiflash -m wp76xx -r” instead of “swiflash -m WP76xx -r”. Next, I found that it is not working on R13. But in case you first downgrade to R12, it works!

I can’t download the R9 version:

Seems the whole source website has problem.
I cannot even download r12.

…
I also found these logs on the broken one:

I found the R11, downgrade my board, and I managed to use the swiflash -r command which erased the board
After that I can connect by ssh 🙂
Mangoh should correct swiflash -r option for the new release
