Hi everyone :
I have a PD (power delivery) function on the imx8mp board.
chip use ptn5110 (cc-logical) with nx20p3483uk (pd-switch)
but now, summary as below, I got my wave-form like this
from partition schematic 'VBUS PD-in' is my typec PD plug-in side
it will rise to 20V; on the other hand, 'VCHG PD-out' is the output side
that will be affected by EN_SNK from ptn5110, I have no idea why pull low EN_SNK
in my wave-form, does anyone suggest that I modify my BSP (driver code to issue EN_SNK low in tcpci.c), or does the hardware design needs to be modified.
