STM32WL5MOC End Node example no debug messages

[matteverze]

Hi,

I was testing the End Node example on a custom board equipped with a STM32WL5MOC module. However, I changed only the UART from UART2 to UART1 in platform settings. I also activate the DMA. However, I can get only "APPLICATION_VERSION: V1.3.1" on the UART terminal and no other messages. Someone knows why?

Thanks.

Matteo

Solution find. It is necessary to enable the interrupt line of the UART. Hint: change also Preemption priority of the USART interrupt and DMA to 2 otherwise the hw timer won't work anymore,
