I know one can use "echo" command to write MAC address to HW_OCOTP_MAC0 via sysfs.

 

But another question is :   MAC address is 48-bit ,however,  each fuse block is 32 bit.

 

All examples that we found is "echo 0x10234567 > /sys/fsl_otp/HW_OCOTP_MAC0" , cannot found 48-bit version.

 

Is separate MAC address to two part, first part (i.e. first 16bit) burn to HW_OCOTP_MAC0 and rest part burn to HW_OCOTP_MAC1 ?

 

Thanks for kindly help!
