Hello Guys,

 

I have iMX6 Quad processor and want to implement Secure Boot. I am using a bit oldversion of U-boot (2013) supplied by a customer. It doesnt support any of the Secure Boot features but I found a patch and made "imxotp" to work and run in u-boot. But the fuse map values that we get using the SRKTOOL provides it only for the "fuse" command. I tried to get the "fuse" patch to work with my version of u-boot but unfortunately I am not successful. Now, I want to know how to convert the "fuse" command values to "imxotp" values.

 

Here is the fuse command values and I am looking how I can get the "imxotp" values

 

hexdump -e '/4 "0x"' -e '/4 "%X""\n"' SRK_1_2_3_4_fuse.bin

0xD2B9E367

0x799AE094

0x89FCCE74

0x69BD3361

0x6E28049D

0x47BD0A4E

0x72DDAAF4

0xCFDADC0D

 

It goes like "fuse prog 3 0 0xD2B9E367" and "fuse prog 3 1 0x799AE094" ...

 

Thanks,

Satya
