Hi Igor, 

   Thank you for getting back to me. I might not have been clear earlier. I had a look at both the documents you sent. However, now that i have blown the SRK0 fuse, the problem that I am currently facing now is that my SD card is unable to boot (which is expected since i blew the SRK0 fuse). I tried changing my CSF file (as I cannot use IMG1_1_sha256_2048_65537_v3_usr_crt.pem and CSF1_1_sha256_2048_65537_v3_usr_crt.pem to sign and authenticate the image) to the one that I pasted above and it still does not work. I am unable to find a solution in the document you sent earlier. Could you kindly advise me on this issue?

Regards, 

Dheeraj

Hello,

  The revoked SRK should not be used more. Therefore it is needed

to sign (and write) the images again with one of the rest SRKs.

  SRK may be selected at boot time through an Install SRK CSF

command.


Have a great day,
Yuri
