Hello
I want to burn eFuse. I use Secure Provisioning Tool. I activated OTFAD ve Authentication.
Tool burns SRK efuses.
But it cannot burn KEK efuse. I see it is burned. But when i try to read with JTAG, they are 0x00000000 value. Also OTFAD cannot run. Only, Authentication image runs. Encrypted image cannot run.
Hi @samet-san
My apologies for the delayed response.
I tested OTFAD on my end using SPTv10 and i.MX RT1170.
I can run an encrypted image ( I took evkbmimxrt1170_mcuboot_opensource.s19 from SPT sample images) If I do not pull-up SW2 as stated in the below table the decryption of the image will not be done.
Are you not missing pulling the related boot_cfg pin on your board?
Below my OTFAD test settings.
Thank you!
Diego
