AFC standby mode
When AFCv2 is inserted into AMC slot voltage measured on 12V power line (standalone mode connector J2) is 0.3V
After power cycle LED13 (PVADJ1 power indicator) light off and on again
after less than 1 second.
This time there is 1.1V on 12V power line.
I’m suspecting one of the power circuit that it’s powered from control pin with 3.3V
At the beginning I measured some nets connected to IC10.
- EN_FMC1_PVADJ and EN_FMC2_PVADJ is always 3.3V
- PVADJ2 is 0.5V in standby mode and 2.5V when board has power
- PVADJ1 is 0.3V after board is plugged in, 2.5V when board has power,
1.8V after turned off
