Multiple Ethernet Port in u-boot

Dear NXP,

 

I am working on T4240RDB-64B machine.

I am using 8 Ethernet Port and able to ping single port at the time by using ethact command.

I want to configure multiple Ethernet Port support. And the u-boot version is 2016

I am following this thread but, I not get anything from that.

Can u-boot support more than one ethernet port?

And I checked the u-boot code and by default u-boot code will support the Single Port only.

I needs to know, is there any possible to make multi port support ?

Thanks & Regards,

VinothS,

As it was explained above, both u-Boot and Linux support multiple network
interfaces, however, the approach is significantly different. Linux
has a full-feature IP network stack which allows a very wide range
of network related operations to be done. You did not specify
what exactly you want to do, thus the answer is, unless you want to
do something fundamentally incorrect from IP networking standpoint,
there should be a way to do that under Linux.


Have a great day,

u-Boot is only a bootloader. You should not expect a full-feature
IP stack functionality from it. u-Boot does support multiple Ethernet
interfaces, but you can use them one at a time. If you connect more than
one Ethernet link to a u-Boot-controlled box, and all links are active,
you have to specify which link to use by assigning a value to  "ethact"
environment variable. If anything above that is desired, e.g. membership
in more than one IP subnet, packet forwarding, advanced diagnostics,
the suggestion is to boot Linux or another OS with a full IP stack
implementation.


Have a great day,

Not sure what exactly feature you are asking about. If you are not familiar with LInux networking, study this.

Hope this helps
