TMS320F28034: CRC not generated successfully at address 0x840

Cherry Zhou

Hi team,

Here's an issue from the customer may need your help:

Flash self-test using STL library found CRC not generated successfully at address 0x840, and Enable CIO function has been disabled.

Could you help check this case? Thanks.

Best Regards,

Hi,

The issue has been resolved but here's a new condition, when doing single step debug it causes the 0x840, CRC value to be cleared, so it is always FALSE.

Thanks and regards,

Cherry

Cherry,

Can you confirm if program is run (no single step) then 0x0840 is correct/has a value? Since this monitoring the data read bus, and single stepping inserts ESTOP0 instruction inline, I suspect that this may corrupt the CRC calculation.

Best,
Matthew
