TMS320F28388D: Modify the boot pin using the dcsm_security_tool project

Part Number: TMS320F28388D


Hi,

I use the dcsm_security_tool project to modify the boot pin,

The configuration of dcsm_security_tool.syscfg is as follows:

The configuration of dcsm.asm is as follows:

Problem: After I Debug this project, I find that the modification is not successful as expected, I look at the memory 0x78000, found that it is not modified correctly. This problem is not necessary, some boards can be modified, some can not, and some boards can be repeated after many times.

    Hello,

    Could you try enabling the PER LINKPOINTER section as well? The .asm file you have generated will fail to program since LINKPOINTER3 is commented out while JLM_ENABLE is being programmed.

    Note that this will program your first zone-select block with some security settings. If you don't wish to use security, you can leave all memory sections as unsecure. You will not be able to program the PER LINKPOINTER block with different values later unless you update the linkpointer.

    Thank you,

    Luke
