Hello everybody,

few months ago I asked about the presence of the internal MAC addresses (for both the Ethernet interfaces) into the iMX93 fusemap:

Since there are these prebuild MAC addresses, I want to read them using Uboot on my custom board. I tried to read in this way:

Now, I know by reading another forum (https://community.nxp.com/t5/i-MX-Processors/IMX93-OCOTP-Permissions/td-p/1858945/page/2) that maybe I haven't the permissions:
