TMS570LC4357: OTP memory map

Part Number: TMS570LC4357
Other Parts Discussed in Thread: UNIFLASH

Hello,

Is there a document that describes the customer OTP memory map?

In the technical reference manual I see the Customer OTP banks but I know the AJSM key is at the beginning of bank0.

I would like to know what address range I can use to store information without conflicting with some other modules.

Thanks,

Martin

    Hello Martin,

    If you write to program the customer OTP, make sure you do not unintentionally write to the AJSM locations (0xF0000000-0xF000000F) or you will lock the part. You can write data starting at address 0xF0000010.
    The size of customer OTP for each flash bank is 4k.
    You can use CCS and uniflash to program the customer OTP. The Customer OTP can not be erased.
