Other Parts Discussed in Thread: C2000WARE

Hi Expert,

Customer writes a flag to 0x82000 as the below content, sometimes, it could not work and the content of 0x82000 is 0xFFFF.

Could you please help to review the software, and give the debug suggestions?

Thanks!

Best Regards

Ranya,

We should check oReturnCheck at each step and make it was successful before proceeding to next state. In the above snippet, the return status is not checked at any stage. That will give some idea if it failed during 'write'.
