Since the PIN of STSPIN32F0 is not enough, it is implemented to view log messages using PA14 (SWD_CLK) as UART.

Since the PIN of STSPIN32F0 is not enough, it is implemented to view log messages using PA14 (SWD_CLK) as UART.

But after that, I can't download it, so please inquire.

​

1. Could you explain that re-download the MCU in this state?​

2. I don't have any PIN, so if there is a way or example to use PA14 as a UART and download it again, I would like to ask if it is possible to share.

PA14 is used for SWD. If you've repurposed it for another use, you can't connect with SWD. You can boot up into the bootloader or use Connect Under Reset to recover the chip.
