CubeMX deleted my usbpd_dpm_user.c · 2019-07-31

Hello there,I don't know if I can call this a bug, but it shouldn't happen at all.Thing goes like this: I have a STM32G071, I enabled UCPD1 and 2, also CMSIS, USBPD library in CubeMXI generated code for SW4STM32, I write my custom board code in usbpd...

Dear members,This is actually a follow up question to my last one STM32G071 UCPD library bug or my problem, but instead of digging deeper and deeper to an already well answered question, and probably out of topic too, I guess I better start a new one...

Hello there, I have a custom board with STM32G071CB for USB Type C PD Source, dual port, RTOS, configured with CubeMX 5.3.0, after writing code on usbpd_dpm_user.c and start debugging, I suspected there are 2+1 strange behavior so I hope somebody can...

You confirmed signal bits arrived the receiver correctly? If that's the case the only solution is to check the receiver code, you can also add a breakpoint in stm32f4xx_hal_spi.c line 697 and check the DR register by yourself when receiving in F413H....

Yes please, because you have three unknown parts in your situation, sender/wire/receiver, so it is better to isolate the no-problem part 1 by 1.

I don't see any problem in my eyes, I still suspect this is hardware problem because sending and receiving 1 byte shouldn't be that problematic. Please confirm if data is correctly put into the wire with a oscillator/multimeter/logic analyzer(one eas...
