Found a bit of an odd issue when switching from MSI (with a 160Mhz sysclock) to HSE (also with a 160Mhz sysclock).We're using the HAL_UART and its giving a error callback with a zero value uart->ErrorCode.The cause of it seems to be in the library HA...

I know what is going on, but I don't know why it is more prevalent with HSE. The 10ppm vs 1% accuracy of the two clocks is likely part of it.The USART is picking up a NE on the protocol from the other device. if (huart->ErrorCode != HAL_UART_ERROR...

Normally I'd agree, and I'd have already done it.But we are using JTAG/JLINK and debugging via the Marus cortex Visual Code plugin - assuming I can get the early version of cortex live watch I have to accept the memory location (not so far) I would b...
