Hello!
New to this forum, I have a 820-02016 board which cannot turn on.
This one does 5.135V ~275mA for a short time, then goes down to ~100mA before shutting down and starting the cycle anew (USB-C multimeter).
Measured the mentioned points:
PP3V8_AON_VDDMAIN - ~3.8v
PPBUS_AON -12.3V then 12.0V and going down during reset
PPVDD_SOC_S1 - ~0.67v
PP1V8_S2 - ~1.8v
PP2V5_AWAKE_NAND - 2.5v
PP1V25_S2 - 1.22v
PP3v3_S2_UPC - 3.28v
PP5v_S2 - 5.2V
PP3v3_UPC0_LDO - 3.25v
PP3v3_UPC1_LDO - 3.25v... -
