Hi Guys,
My Ultra 96 just died, I was stepping through with the debugger and noticed the fan stopping.
All lights out, and now won't power up.
I have tested the PSU and that is fine.
Anyone any ideas?
Cheers
Andy

Reviving this thread since I have the same problem, just with an Ultra96-V2. Reading 12.1 V on VIN, 3.32 V on 3V3_PRI, 0 V on 5V0. Curiously, I'm also reading 0 V on the KILL_N input to the ON/OFF controller and the same for the EN output of it (which is obviously why the 5V regulator does not turn on). Has anybody looked into if this might be a design flaw, particularly regarding the ON/OFF controller circuit? What can I do to bring my board back to life?
Also, does anyone know where to find the datasheet for the SLG4G42480V ON/OFF controller? Google tells me nothing beyond that it's probably manufactured by Dialog and distributed by Avnet...
