Hi,
I have a board with i.MX 6UltraLite (MCIMX6G2CVM05AB) and a LAN connection by the PHY transceiver KSZ8081RNBIA-TR of Microchip.
I see the MAC address changes every time a reset the board. So I need some explanation:
- Is the i.MX 6UltraLite who generates the MAC address?
- Is there a way to have a univoque value for the MAC address?
Best regards,
Andrea
Hello @AndreaB-17
If you want an unique MAC address you can burn the fuses:
21B_C620 -> Value of OTP Bank4 Word2 (MAC Address) (OCOTP_MAC0)
21B_C630 -> Value of OTP Bank4 Word3 (MAC Address) (OCOTP_MAC1)
You can do it in U-boot with fuse prog.
Best regards.
Salas.
