imx8 quad eth0 and eth1

[SoftMicro]

We have a custom board using an Apalis i.mx8 Quad Max running Android 10

We are trying to use both eth0 and eth1 ports on the custom boards using 2 x KSZ9131 phy's. We can bring up individual phy's OK (ping etc) but cannot bring up and use both phy's.

apalis_8qm:/ # ifconfig eth1 up

I am using this dhcpcd set up in init.rc -

service dhcpcd_eth0 /system/bin/dhcpcd -ABKL eth0 eth1
class main
disabled
oneshot

service iprenew_eth0 /system/bin/dhcpcd -n eth0 eth1
class main
disabled
oneshot

Has anyone used both eth0 and eth1 with i.mx8 and Android 10?

Is the second ip address the issue?

Thank you.

Hi,

@Rita_Wang 

I have EthernetDual but it's some missing network interfaces to work with Android 13. I cannot get it to build yet. Some interfaces from NetworkUtils error.

Can you send me  EthernetDual(2).tar ?

Thanks.

Hello @Rita_Wang ,
we are working on a custom board based on IMX8MP, where in we plan to use dual Ethernet on android 11. Could you please share me - 0001-android-device-nxp-dual-ethernet.patch and EthernetDual(2).tar

Thank you in advance.

Hello @Rita_Wang , @SoftMicro 

I'm using imx8qm on custom board with Android 12 and I'm having the same issue where the host is unreachable when pinging from eth0 and eth1.
I could find the 0001-android-device-nxp-dual-ethernet.patch but I can't get the EthernetDual(2).tar

Could you please share this tarball?

Thank you!

[Rita_Wang]

I share you by the email, please have a check.

[sig0912]

Thanks for sharing.

I just tried it but there are some missing network interfaces to work with Android 12. I cannot get it to build yet. Some interfaces from NetworkUtils are now deprecated for Android 12 and I'm now looking at the NetworkScore instead which seems to be the one to use.

I don't really do app like that so I'm a bit lost with the java files. Could you please explain what I should change to make EthernetDual package compatible with Android 12?

Thank you

[Rita_Wang]

 I email to you, please have a check.

[SoftMicro]

I got your email with no content!

[Rita_Wang]

Have you got the 0001-android-device-nxp-dual-ethernet(4) and EthernetDual(2).tar I share to you?

Hi @Rita_Wang ,

Could you share these 2 packages with me?

Now I am also tring to use 2 ethernets on Imx8mm with android 9. And I am searching any useful information.

Thanks

Chad

hI B45499, we are facing the same issue. Can I get these 2 files from you?
It will be very helpful.

[Rita_Wang]

Dear @vedantteksun ,

I email to you, please have a check. These patches are for the i.MX8MP, the method is the same, you can refer to.

Wish you have a nice day

Best Regards

Rita

[SoftMicro]

I can't access "NXP Office365 portal" to get these files. Can you email these directly or post here.

Thanks

[Rita_Wang]

@SoftMicro This patch is for the i.MX8MP, for the i.MX8QM you can refer to

[SoftMicro]

Thank you so much b45499. I will try this out when I return from vacation in a week.

This fixed the issues, thank you
