TMS320F28388S: FLSEM Register

Part Number: TMS320F28388S

Hello Champs,

We set that F28388S CPU1 all flash sectors and CM all flash sectors are secured by DCSM Zone 1.

After setting FLSEM register to 0xA501, we found that the F28388S CPU1 flash can be erased and programmed but CM flash still cannot be erased and programmed.

Would you please kindly help? Are there any other registers that need to be set? Thanks!

Best Regards,

Linda

    Are you setting this from CPU1 or CM ? If only from CPU1 then please try setting this from CM when trying CM flash operation and see if that resolves the issue.
