After changing only a little in my Code, the Application always ends up in the Dummy_Handler();
the error occurs after that code:
if (xSemaphoreTakeFromISR(uart_irq, portMAX_Delay)) (selfwirtten code)
ldr r0, [r6]
movs r1, #0
mov.w r2, #4294967295
cmp ro, #0
if(prvISQueueEmpty(pxQueue) != pdFALSE) (out of the FreeRTOS/queue.c)
cmp.w r8, #0
from here it jumps into the Dummy Handler.
Unfortunately i have no clue what this error is related to? Could there be a memory fault?
Thanks in advance for any help.
