How to modify default routing table on STM32MP157 with OpenSTlinux

[yclin]

Hi,

I'm new of linux.

Now I have two network interface on my board, end0 for ethernet & en1u2i4 for 4G modem.

The ethenet(end0) is directly connected to my PC only for development that I can use ssh to connect my board.

And I want the other connection transfered by 4G modem(en1u2i4), so I use "route del default" to delete the first rule of the routing table.

 

That will work. But I need to do this everytime the board boot up.

Are there settings can be modified in the system? Or should I write a script to do "route del" command with a startup service?

Thank you.

Hi @yclin,

Indeed, you can write a script to do the commands that you need to configure your network interfaces.

Maybe (I haven’t tested it) you can also use the configuration files as explained in the https://wiki.st.com/stm32mpu/wiki/How_to_configure_ethernet_interface STM32 MPU wiki article, and in the official documentation of systemd-networkd that is referenced in this article (https://www.freedesktop.org/software/systemd/man/latest/systemd.network.html).

Hope this information helps.

Regards,

JC.
