Hello, I am using USB -FS and it seems conflict with UART-1, VBUS pin PA9. I am using STM32H743VIT6 100 PIN, and UART -2 I am using for debugging but it does not work, Why? For the previous UART -1 runs fine for debugging, STMcubeProgrammer i am using

Hello,

Every time I am using UART -1 of the same controller and its works fine, but for now I am using USB -FS and for that VBUS pin I am using for the VBUS sensing,

Wher, this VBUS Sense pin conflict with the UART-1 which is the PA9 pin of the STM32H743VIT6100-pinn package controller.

So that i used UART-2 for the debugging, but its not works, Why so,

I am using STMCubeProgrammer for the same. and it has the latest version,

the error messages are, Read errors Timeout error, in the STMCubeProgrammer, Not able to load the code also and the controller also not goes into the boot mode, where i have checked all physical connections, and rechecked with UART-1 then it gets works fine, But not works for the UART-2.

Give me solutions on the same.

On which pins are you using UART2?
