TMS320F28388D: Changing Bootconfig pins with OTP Programming and DCSM.

Part Number: TMS320F28388D
Other Parts Discussed in Thread: SYSCONFIG

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
