RM48L952: Bootloader in OTP memory?

Troy Erickson

Part Number: RM48L952

Hello All,

I would like to implement a small bootloader and was curious if it was possible to place the bootloader in one of the small OTP memory sections? I have seen previous TI micro controllers support this feature but am thinking the RM48L952 does not since it's not mentioned anywhere. 

Thanks!

    Hi Troy,

    The answer is no. The OTP is meant for one time program only. The size of customer OTP is 4k. You should only store data, not your application program in customer OTP.

    If you write to 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.
