Hi,

I want to use flexCan interrupt, and I debug it with S32 Debug Probe. The flexCan work in loop-back mode.

I set a breakpoint at can data sending function, I find the breakpoint cause a problem that the CPU can not enter recieve IRQ function.

When pause program, IFLAG1 and IMASK1 register BIT1 is '1'. it indicate the interrupt occur，but not execute IRQ function.

Hi VaneB,

chip: S32R45

S32DS version: 3.4

RTD version: S32 RTD AUTOSAR 4.4 Version 4.0.0

project: FlexCAN_Ip_Example_S32R45_M7

The FlexCan Project demo use polling to recieve data, i have modified it to use FlexCan receive interrupt.

When set a breakpoint at FlexCAN_Ip_Send() function, this problem occur; when no breakpoint, no problem.
