I am looking for the "Device Fuse Map" documentation for the i.MX93.
It is mentioned in the Edgelock secure enclave user guide, edgelock enclave hardware security module API, code signing tool user guide. The i.MX93 application processor reference manual contains a chapter on Fusemap, but does not specify more than the boot related fuses.
My expectation is that this fuse-map contains the locations of the SRK hash
and also explain the related bits on enabling secure boot and close the device.
My goal is to create a key-provisioning tool which runs under Linux on the target,
which is used to fuse the SRKS (due to not having access to the serial console or boot pins after manufacturing), but I want to be very sure that I am programming the correct addresses via the HSM.
Thank you.
Microsoft Edge seems not to support showing those attachments, so had to install Acrobat Reader.
Fuse map is an excel form which can be viewed by changing item from the left panel of i.MX93 application processor reference manual as shown below.
There are more information provided, such as SRK fuse, if you access to i.MX93 application processor security reference manual.
As the fuse information you require are SRK Hash and enabling secure boot, you can refer to the guide - secure_boot
