IMX93 OCOTP Permissions

[Jarbo]

Hello,

I am working with an IMX93 and I am trying to record the MAC fuses (0x4ec and 0x4f2), the problem I am encountering is that it is giving me a permissions error and I cannot find OCOTP_LOCK to be able to record these fuses, could you please help me?

Thank you so much!

PS: NVMEM_PATH = "/sys/devices/platform/soc@0/47510000.efuse/fsb_s400_fuse0/nvmem"
