Currently my trace32 has curious problem. Flash download is fine, but when I have set breakpoint, T32 doesn't stop there. I have confirmed code works fine, but trace32 doesn't stop. I have two pod(?) for ARM7/9, 9. both has same problem on ARM7 and ARM9 board. And for external memory CPU, instruction is not displayed correctly after running board once. 1st and 2nd byte is same and 3rd and 4th byte is same. I am having problem in woking for this. Please let me solve this problem. Thanks.

Try increasing your memory wait states (but I don't think it was that). But as has aleady been said asking Lauterbach is the way to go here. tim

Hi man, I never have worked with a satisfatory debugger. It's easier you able a trace (/var/log/messages for instace) and probe the bug visually. I never work with trace32. If you prove that it is good, I'll use it too. Have a nice day.

I have tried both BP in flash and RAM. I have tried on-chip BP and H/W bp isn't set.

Do you mean it isn't reached? Are you setting the BP at a source line or at an ASM line? If the former, I would guess that you are suffering an 'optimisation' quirk. tim
