I.MX6 Ultralite pullups PORn to +SNVS Internally with weak 100k Pullup Resistor
Our PMIC PF3001A7 PORn output its open drain
So the SoC pullups this line
If i place the Agilent U1257B multimeter or Scope probes over SoC POR_n Testpoint the Soc Resets!
I also Added external 10k pullup to SNVS but This till ocurs
Perhaps Probe Capacitance ...
