Dear all,

I'm working on a custom board based on an i.MX6 Dual Lite.
I've set a MAC address on OCOTP, and I can see it :

barebox@Main Board:/ devinfo ocotp0
Parameters:
  mac_addr: 70:82:0e:12:73:6f (type: MAC)
  mac_addr0: 70:82:0e:12:73:6f (type: MAC)
  permanent_write_enable: 0 (type: bool)
  sense_enable: 0 (type: bool)

The issue is that I can't get it from eth0 :

barebox@Chrysalis Main Board:/ devinfo eth0
Parameters:
  ethaddr: 00:00:00:00:00:00 (type: MAC)
  gateway: 192.1.1.100 (type: ipv4)
  ipaddr: 0.0.0.0 (type: ipv4)
  linux.bootargs: ip=0.0.0.0:192.1.1.46:192.1.1.100:255.255.255.0:::
(type: string)
  linux.devname:  (type: string)
  mode: static (type: enum) (values: "dhcp", "static", "disabled")
  netmask: 255.255.255.0 (type: ipv4)
  serverip: 192.1.1.46 (type: string)

My operating system's driver does not see it neither ...

Am I missing something?

Yes: https://barebox.org/doc/latest/devicetree/bindings/misc/fsl,imx-ocotp.html

Check the other i.MX board in arch/arm/dts for an example.

Many thanks !

Sorry for the noise...

Best regards,
Antoine
