To change the MAC address, I had MAC Writh the following instruction as below:

 

[Mac Address Command for MFG Tool] --> MAC Address : 00:01:6F:01:FF:FF
<CMD state="Updater" type="push" body="$ ls /sys/fsl_otp ">Showing HW_OCOTP fuse bank</CMD>
<CMD state="Updater" type="push" body="$ echo 0x6F01FFFF > /sys/fsl_otp/HW_OCOTP_MAC0">write 0x6F01FFFF to HW_OCOTP_MAC0 fuse bank</CMD>
<CMD state="Updater" type="push" body="$ echo 0x0001 > /sys/fsl_otp/HW_OCOTP_MAC0">write 0x0001 to HW_OCOTP_MAC1 fuse bank</CMD>
<CMD state="Updater" type="push" body="$ cat /sys/fsl_otp/HW_OCOTP_MAC0">Read value from HW_OCOTP_MAC0 fuse bank</CMD>

 

 

I understand that it is can not be changed again if the address was used once,
Is there any way to translate them into instructions?
