In the pin list fails to identify the QSPI NCS pin candidates, I had to review schematic

PG6 QSPI_BK1_NCS, PC11 QSPI_BK2_NCS / SDIO_D3

Could do a better job of identify USART3 with the VCP pins in the list. USART3 mentioned once only

    + same about C0316-DK.

    The UM could explain better how to use the VCP on ST-LINK vs. external (BT) UART.

    Hello @Pavel A.​ ,

    Please check UM2969 chapter 7.2 CN2 connector and chapter 6.5.3 for VCP and UART description on HW side.

    Could you please tell us what you expect as "explain better how to use the VCP on ST-LINK vs. external (BT) UART". What are the missing details?

    Thank you.

    Thank you Kaouthar for replying. I don't have a BT adapter referenced in C0316-DK docum and want to use USART1 TX & RX via VCP of the included ST-LINK-mods. But TX from STM32C0 doesn't go out. The schematic shows some interconnection of the USART1 pins with the "BT" connector. One of DIP switches also can be related.

    Or I'm using the wrong USART or pins.

    So I'd appreciate if clear instructions for this usage were included in the user guide.
