Sequans Firmware Update Fails

Re: Sequans Firmware Update Fails

I'm also having problems updating the modem on a FiPY to NB-IoT, using the direct UART method as I don't have the board with the SD card. Please can someone suggest how to fix this or update the documentation if this method of updating is no longer supported.

Good news, I got this to work by commenting out the code in sqnsupgrade.py which I assume tries to retrieve the modem crashdump (the two occurrences in the __run method).

I guess the crashes on my modem were longer than the 100 byte assumption in the code.
