Help needed [Oops] while flashing a sercomm na930

Hello

I'm messing around with a sercomm na930. I can see that it is supported since a while, but it doesn't work on my side. The only OpenWrt versions that works are the 17-ish (), and some generic firmwares, but not the sercomm na930 specific.
Here is the stack trace when I try to flash the firmware fia TFTP :

Any help on this would be appreciated :smiley:
thanks

Could you post the complete boot log to get a bit more context where this is crashing?
