I also try use the example dcsm_security_tool.

I try flash the .out to the board and use the On-Chip Flash window to modify the Z1-GRABSECT1 from 0x0AAAAAAA to 0x0AAAAAA5.

Then click the program, but the failed info shows as below.

I guess it maybe ECC problem? But I did find how to fix this.

I also tried to modify the Syscfg to generate the .out which config the Flash sector 0 and Flash sector 1 to secure Zone1.

When flash the .out to board,also failed.

Hi W Z,

If you've already programmed Z1-GRABSECT to a custom value, you won't be able to reprogram it, you will need to update the linkpointer and program your desired values in a new zone select block.

Thank you,

Luke

It depends on your security requirements for your application. If you have any questions about what protections are offered by DCSM I can clarify those.
