How can I modify the MAC address written on imx6 ROM?

[jackeyko]

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?

Hello,

 There are several options to configure the MAC : "the MAC address can be set through
the kernel command line, kernel device tree DTS file, OCOTP, or MAC registers set by
bootloader, such as U-Boot."

Have a great day,
Yuri
