For K22F120M board and MQX4.1 OS, I found if I set a breakpont in interrupt routine, once this interrupt be trigger, KDS will stop at this breakpoint, but at this time, any step (step in, step return, step over) will not work, even 'run' also will not work. the KDS console keep printting like this "Read 2 bytes @ address 0x0000060c (Data = 0xB408)"
.The same project in IAR enviroment , the same breakpoint at interrupt routine will work as normal.
Any one has the same problem ? Any idea about this ?
