Hi Hans
Thanks for your help so far?
So I checked the mainboard by
- supplying 3V3 from a linear regulator - CPU runs (can connect putty)
- installing the 3V3 SMPS board then applying 12V to the switched +12V line - runs OK so the 3V3 SMPS is good
- supplying 5V from linear regulator - with a voltage divider to feed ADC_5V - as you can see the measured 5V is looking good but the processor still detects an error - see screenshot
Ideas how to bypass that so I can complete checks ?
Regards
Rick
