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.
=> fuse prog 0 708 0xa295fc11
Best Regards,
-Mike
Hello,
i.MX8M RM contains fusemap chapter, in particular in Table 6-43 (Fusemap Descriptions)
of i.MX 8M Dual/8M QuadLite/8M Quad Reference Manual, Rev. 2, 08/2019, UNIQUE_ID
fuse is located in Fuse Address offsets (0x410 and) 0x420. To get the values -
read the bank 0, words 1 and 2.
fuse read 0 1
fuse read 0 2
As for the General Purpose fuse registers - some of them are reserved, in any case we cannot
not guarantee them for free using.
Regards,
Yuri.
