data abort error in sys_selftest

Other Parts Discussed in Thread: HALCOGEN, TMS570LS0332

Hi,

I am using the TMS570LS0332, CCS6.1 and halcogen 4.1.

I have a program on a custom board that I have been using without issue. However, I now get a data abort when running the system selftest on the line

ramread = tcramA2bit;

I can't figure out what is causing the error or how to get around it.

Any thoughts?

Hi David,

This data abort is intentionally generated as part of verification of the ECC checking mechanism. The data abort handler has code to identify an intentional abort from an unintentional one.

Thanks.

I swear that I had been getting a data abort right after main and I was trying to track it down, I guess I went too far.

The abort seems to have disappeared from my main code for now though, so all is well.
