RED 15W not booting - sample of console log ?

Hi,

i have a Sophos RED15W from Nov. 2019, that is only showing this log on the Console Port.
LED´s show (Power, Router,Internet, Tunnel = green ; System = red).

NAND boot...
Second program loader running in sram...

Can someone from the Community post or send me a sample of a normal uboot / console log during power on?

I will try to solder the JTAG/CPU Port to the PCB and hook up some JTAG Tools for debugging.
Maybe i can bring this device back to live or install OpenWrt ...

That would be great.

Thanks

Jürgen
