TMS320F28377S: How to enable Flash Protection for code Locking

Hi Fabio,

I believe Uniflash will automatically unlock the DCSM using the passwords you've provided in the CSMPSWD GUI. Can you reset Uniflash and attempt to read the flash without your custom passwords specified?

Thank you,

Luke

I just try this, but memory flash is always accessable

Have you secured flash memories via the GRABSECT OTP locations? Or did you only program custom CSM passwords? You must configure the GRABSECT fields to secure the flash.

Thank you,

Luke

Thank you Luke. I configured GRABSEC and the memory is secure. 

I used FlashBoot. When I Program flash the FW starts in correct way but if I reset the board the FW doesn't start.

Probably problem is in the boot option... 

if you reset the device and flash boot is enabled the debugger won't be able to connect. If you are testing with a debugger connected can you use wait boot instead?
