Hello
I'am working on an project with 8 timers (APP SYSTM_002) and the timers work "ON_SHOT" in a time range of 850us up to 2000us. I have also two interrupts from UART Rx FIFO. After a while (between 5min and 120min) the programm go's into the exception "BusFault_Handler". My question is from where is this exception startet or is this a stack overflow problem?

Thank's for help!
