Hello - I'm writing a simple usart console application using RTX with MDK-ARM v3.20 on an MCBSTM32. The code ends up in either MemManage_Handler or HardFault_Handler when setting an event via isr_evt_set in the interrupt that services the USART. I get the same result when running the MCBSTM32\RTX_Traffic example, which is similar to my application. Is there anyone out there running this example successfully? Thanks -
