Hi,

I need to store bd_addr (48 bits) or more of data on the i.MX6 OTP fuses.

And we find the related documentation in the reference manual.

Chapter 45 On-Chip OTP (OCOTP) Controller:

Can I used all "RESERVED" registers to store our customization data?

Thanks,

Peter

Hi, I have the same question. Have you found the answer? Where did you store the data on uFuse?

I don't think so. You can use GP1,GP2 to store data.

Specially for your mac address,you can use MAC0,MAC1 to store.

I would not recommend using GPR1 or 2 for general data storage.  These locations are used by the i.MX6 ROM code.

Can you advise on any other OTP fuses for storing customization data then?
