STM32MP1 - MAC address

[jgauthier]

Greetings,

  I have a few STM32MP1 boards. One of which I have configures the OS on, and custom applications.

I copied the SD card and put it in another one.  The MAC address is the same. I read an STM article about the MAC address and "fuse sense 0 57 2" shows me the correct MAC address.  So it must be in software somewhere.  Where?

Hello @jgauthier ,

Yes this is a typical issue when we copy a SD card into another, it results in this MAC address error.

To tackle it, you will need to stop in U-Boot shell, and process an "erase env" to delete the config with the MAC address, and get a new one.

Hope it will help you,
Kind regards,
Erwan.
