Accessing UCPD monitor via USB to UART bridge

[Marosh]

Hello,
I would like to ask a question, if it is possible to access UCPD monitor via USB-UART bridge? I am following tutorial AN5418, with nucleo G0B1RE and SNK1M1 shield. Everything works fine when I use st-link, but when using uart bridge I dont see the board in board selection of UCPD and can log data only to UCPD trace...

I have found out, that one can make it to work when one desolderes SB16 and SB15 from st-link on nucleo and connects LPUART to TX and RX of JP6. But is it also possible to make it work with USB-UART bridge from another vendor?

Thanks,
Marosh

Hi @Marosh 

Did you check _GUI_INTERFACE and _TRACE preprocessors? You should have tracer source files as well to enable tracer features.

Yes they are ticked in CubeMX according to the AN5418. The point is that using same software it all works when TX and RX fed to st-link and then from st-link to PC but it doesn't work when TX and RX are fed to uart-usb bridge from different vendor. It is rather a question of interest whether I am tied to using st-link or other variants should also work..
