Hi,
I try to use the uart 1 and the the edge port module IRQ1 in input interrupt.
My 2 codes are good separately.
But when I use both then the detection of the IRQ1 functions one time.
The UART functions at 115200bauds and IPL = 2 and all ICR are different, I use asm_set_ipl before before modify all IMR.

Someone can help me?
thanks,
Best regards

Yohan
