Thanks Shivani and Yuri,
Is there a unique ID in the fusemap that we can read?
Also - can we use the _GP registers listed on page 850 of the RM: HCOTP_HW_OCOTP_GP10 etc to store some data specificaly for our software?
Also - I'm finding that the addressing from the blog link above is not working with the version of uboot that I have.
