TMS320F28388D: Changing Bootconfig pins with OTP Programming and DCSM.

Tool/software:

Changing Bootconfig pins with OTP Programming and DCSM.

I want to change bootconfig pin by programming OTP. (Default:GPIO72 GPIO84)
BMSP1:GPIO128 BMSP0:GPIO121

I successfully try this pins by changing EMU_BOOTPIN_CONFIG and EMU_BOOTDEF_LOW.

I couldn't directly change the values over Z1_OTP_BOOTPIN_CONFIG(0x78008) and Z1_OTP_BOOTDEF_LOW(0x7800C) address.

Is this settings enough the change bootconfig pins? Can i also need to program ZONE1 LINKPOINTER?

Best regards.

    HI Attila,

    You don't need to modify the LINKPOINTER. If using SysConfig you only need to select the boot modes and boot mode select pins. Note that this will program OTP(one-time-programmable) values so you can only program these settings once.

    Thank you,

    Luke
