What are the OTP(fuse memory) locations available for user to program user data into IMXRT1052?

Hi,

We are using IMXRT1052 in our application. We want to program some data into OTP(fuse memory) locations of the processor. We went through the reference manual of IMXRT1052 and found that many of the OTP(fuse memory) is used by hardware or is reserved for future use.

We also found that there are few general purpose fuse register mentioned in the OTP map(fuse memory map) which are,

1] 32-bits General Purpose Fuse Register 3
2] 32-bits General Purpose Fuse Register 1
3]32-bits General Purpose Fuse Register 2
4] 32-bits Software General Purpose Fuse Register

Could you please confirm that we can use these general purpose fuse registers to program user data into OTP(fuse memory)?

Hi @bhagatpsb ,

Thanks for your interest in NXP IMX RT series. I'd like to provide you the support.

1. You are right. GP1 GP2 GP3 can be used for (General Purpose Customer Defined Info).

2. But SW_GP1 SW_GP2 can not.

Hope it helps!

Best regards,
