Hi,
We would like to use 128bit unique hardware identifier on the i.MX 8M Plus processor.
In "Table 6-35. Fusemap Descriptions" of i.MX 8M Plus Applications Processor Reference Manual (IMX8MPRM, Rev. 1, 06/2021), shows UNIQUE_ID in multiple places:
- The lower 64bits [63:0] are located at Fuse Address 0x410~0x430.
- The upper 64bits [127:64] are located at Fuse Address 0xE00~0xE10.
It seems that the lower 64bits are exposed as /sys/devices/soc0/serial_number in Linux, but I cannot find a way to read the upper 64bits.
We use yocto/hardknott.
Thanks,
tamo2
