Hi, TI Team.

I use EARM version 9.60.3 and SDK version 9.11.

When attempting to debug using EWARM, an error occurs. (See details below)

Please let me know how to resolve the issue.

Hello,

How are you generating the CRC for the CCFG in IAR?

This error indicates that whatever CRC that is in the CCFG does not match what's being calculated by IAR. This means that the CCFG CRC doesn't match what the contents should be.

Hi, Nima.

Thanks for the reply.

After conducting our own research, we found that the error was resolved by following the method outlined in the link below.

This method seems to be a kind of patch, but is it a solution guaranteed by TI?

Best Regards.

Hi,

Yes that would be a solution. We don't have the ability to control IAR's integration of our tools, so using the IAR version stated in the release notes of the device with any needed patches would be required.

Best,
