Other Parts Discussed in Thread: Z-STACK, CC2538

HI Ti,

I am using Zstack 1.2.2 with IAR ARM 7.30

I got following error couple of times in past and I don't know what does it mean. Can you clarify please?

Project build and complies Ok.

If you use unmodified Z-Stack example, do you still have this problem?

Not when building. But when I hit Download and debug I get this error.

Do you use IAR EWARM 7.30.4?

Try to remove and reinstall Z-Stack. Build SampleLight and debug it to see if you still have this problem.

SampleLight doesn't have this error.
What is root cause for this error? Is it a HW or SW issue? Is it serious? BTW I am not using TI Dek Kits.

I never see this error on my environment. I suspect this is HW issue. Are you sure your CC2538 PCB is good? If you use Flash Programmer 2, can it detect your CC2538 HW?
