What causes SRC to send Hard Reset during charging?

CZubi.1 · ‎2020-04-22

I am working on a SNK device. Power negotiation goes well, an explicit contract is reached. Charging starts. Sometime into charging, SNK gets a Hard Reset. What could cause a SRC to send a HARD RESET during charging?

Dear @CZubi.1 ,

Could you please provide a .cpd trace from your issue? Further information available in the following link: https://wiki.st.com/stm32mcu/wiki/USB_Power_Delivery_overview#Specific_tools.

I have a look at the log... Could you please indicate your HW Setup? STM32 + TCPC component? which is your ST MCU?

Hi Yohann,

MCU is STM32F030CC + PTN5110 TCPC
