I'm looking at AN2606, section 65.1 and it looks like UART 4 can NOT be used by the bootloader to load FW into the part. Can someone confirm that is true?

I have a few boards using an STM32L4 part.Some of the boards are working as expected, but others are not. The ones that don't work reach a timeout in the SystemClock_Config() function call. Specifically, they time out in the while loop at line 558 of...

I have a strange issue here. I'm trying to do a short, blocking, UART transmission.I have a 23 byte uint8_t array ( MSG ) that I construct before calling the HAL_UART_Transmit() function to send the data. (SLAVE_MSG_SIZE = 23, UART is a pointer to th...
