Same MAC Address

[alanb2121]

I have to MatrixTV's and see they both have the same MAC address. I assume the OS is not getting the MAC value from the hardware? What is the best way to change the MAC address?

Thanks

MAC in hardware is all the same... easy to change though

ifconfig eth0 hw ether 00:28:C7:0A:42:A2

But how do you make it persistent through boots?

[updatelee]

Put it in the network startup script.

Thanks, so what is the script called? Where is it located?

[updatelee]

unsure, cant rem. I dont use matrixtv anymore. its in /etc either init.d or system or something to that effect.

try

grep -r eth0 /etc/*

see what comes up, it'll look like ifup or ifconfig

I wasn't able to find anywhere where I could set the MAC address using an exisitng conf file. In the end I added the following line to /usr/bin/licd_pre.sh

/sbin/ifconfig eth0 hw ether 00:00:00:00:00:05

I'm not familiar enough with Systemd so this seemed like a good alternative.

Really the MAC address on the NIC should be unique for each MatrixTV. I assume TBS are using a cheap no brand NIC interface.

[updatelee]

They are using an ar8035 nic.

There is a way to set it perminitly in u-boot but I've never bothered.

Hi All

Really sorry for this ,Please write an email to our support#tbsdtv,we will assign a MAC address to you like our DVB cards.
And then you can use this command in u-boot
such as
imxotp blow --force 22 0xABC02A1B The last four byte
imxotp blow --force 23 0x0022 The first two byte

After write ,you can not change it any more,so please enter the right MAC address.

Thanks

Kind Regards
