Ethernet adress in startup script

Hi,

in which file should I enter the ethernet adress that eth0 goes up and running?

I tried /mnt/emmc/init.sh but I think that some other task will force it down. I can see that wifi.sh will work perfectly and the board goes to wlan.

But I would like to use eth0 instead than wlan. I'm not sure which is correct place to put ifconfig configuration lines. Any idea?

If you have it defined, use this for the command. Could you provide more information of what you wish to do?

Hi,

ifconfig is the command, but in where you should enter this to get board boot with this argument every time?

I did followed instructions from https://se.mathworks.com/matlabcentral/fileexchange/66004-avnet-minized-support-package-for-simulink

There are advised how to connect wlan or eth0. The wlan will be started every time when board is rebooted. But problem is where to declare eth0 (usb ethernet) parameters. If I reboot the minized, all the typical configuration files are re-written.

It seem like most of all the files and directories are rewritten during boot up process. But is there a way to add own custom script for example to bring usb ethernet up?

This mathworks example works if you dont boot the board again, but normally with this process you will boot the board again each time when you download new software/hardware. So this example is not very handy. But how to make usb ethernet adress permanent?

A cron script could reconfigure as you wish. Check out this where it says @reboot.
