Write the MAC-Address into the OTP-Register 64/65 with the command line

Wed Sep 11, 2019 5:25 am

Hello everyone,

i asked the same question in the german Raspberry Pi-Forum, but nobody there can help me:
https://forum-raspberrypi.de/forum/thre ... schreiben/

I´m looking for a possibility to write the Mac-Address into the OTP-Register 64/65 with the command line.
I found the Following solution with the config.txt:
https://www.raspberrypi.org/documentati ... /README.md
https://www.raspberrypi.org/documentati ... otpbits.md
https://www.raspberrypi.org/forums/view ... p?t=231700

Write:
program_mac_address=xx:xx:xx:xx:xx:xx
in the config.txt works fine.

However, I need the input from the command line, or with a possibility about Python I would be happy too.
With the program vcmailbox I can only describe OTP register 36 to 43 as I understand it.

Do you know a way how I can write the OTP register 64/65 over the command line?

Greetings
Dominik

You can't - there is no mechanism for that on the Compute Module.
