Global variable problem (the program got stuck after just executing the assignment )

[ycgxy1650601]

HI:
    Software version: CodeWarrior 2.10   /    hardware version: mpc5606b borad

Problem: when I debug the program from step 1 to step 2 by single step debugging(see Figure 1),  the program got stuck.  The software interface is showed in figure 2 when the program got stuck.   I click the stop button,   then the software interface is shown in Figure 3.   I find the result that the pointer always point to  "00001020 e800 se_ B 00001020" after clicking the stop button.   I have tried many times, the result never change(PC 00001020 and 00001020 e800 se_ B 00001020).  The global variable currentprot is described in Figure 4.

Why the program got stuck after executing the assignment statement of global variable currentprot by single step debugging?

THANKS

Hello,

I find the result that the pointer always point to "00001020 e800 se_ B 00001020" after clicking the stop button. I have tried many times, the result never change(PC 00001020 and 00001020 e800 se_ B 00001020). The global variable currentprot is described in Figure 4.

The program is not stuck.

it just run into endless loop like while(1). uC is working correctly. Please check you source code.

best regards,
Peter
