I'm using i.MX6 SOLO SOM. And I'm trying to fuse the SOM by using the below command.
CFG4: (eMMC fuse)
echo 0x4060 > /sys/fsl_otp/HW_OCOTP_CFG4
echo 0x10 > /sys/fsl_otp/HW_OCOTP_CFG5
When I fused CFG4 and read I get the same value which I was written. But when I fuse the CFG5 and read I get the wrong value.
$ echo 0x10 > /sys/fsl_otp/HW_OCOTP_CFG5
$ cat /sys/fsl_otp/HW_OCOTP_CFG5
These issue only occurs in 10 out of 100 SOM in a same slot.
Hoping for better guidance.
Thanks and Regards,
