I found something in an old baseline release document....

2014-05-23 GAA30782GAA

First baseline for GECB Computing Core V2 (AxA26800AVPx)
Not compatible for GECB Computing Core V1 (AxA26800AMLx)
Changes:
• For GECB CC V2 only

(You can have the doc if you want to...)

I think it is a lost cause, the V2 core was definitely not designed to work on V1 software. The only option must be to get the correct IO board from Otis...
