CCS/TMS320F280049: SFR dump data in register exported files is changed.

Hitoshi-san,

What is SFR in this context?

Do I understand that the CLA, CLB and DMA registers shown on the left of slide 3 exist in one export but not in another export?  (are they missing or different values).

Is this consistent - i.e. does it always occurs with the same registers?

Is anything running on the device?  Some peripherals will continue to execute when CCS is halted if they are setup for free run.  

Is the CPU halted in the same place each time the registers are exported? 

Is the debug context the same (i.e. C28x vs CLA)

Hitoshi-san,

Can you help explain what they are comparing?

Are they doing the following?

1) Halting the 28x core

2) exporting the registers

3) waiting a bit (while still halted)

4) exporting then again

5) comparing the results  

The differences shown in the screen capture are related to CLA and CLB.  The CLA can run independently from the C28x core.  Is the CLA also halted?  I will likely have to send this over to the C2000 team.

Regards,
John
