How to make the customer am335x board both wired and wireless network work simultaneously ?

[daemo...@163.com]

I built a cutomer board based on beagle bone black but added the wl1835 for wireless. I hope the customer board can use both wired and wireless network simultaneously.

Now I can boot the linux with wired network well. But when I add the wireless overlay in uEnv.txt in RED as below.

#Docs: elinux.org/Beagleboard:U-boot_partitioning_layout_2.0

.....................

The board booted  with wrieless network well but there was no eth0 interface anymore.

After I commented the RED line in uEnv.txt the eth0 interface showed again and work well. 

Could someone tell me what I should do to make both wired and wireless network work simultaneously ?

Thank you very much.

That's expected as teh "BeagleBone Green Wireless" doesn't have an
ethernet port..

So you'll need to fork:

BB-BBGW-WL1835-00A0.dts

and remove this section:

https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-BBGW-WL1835-00A0.dts#L143-L148

Hi Robert Nelson

Thanks for your help. 

I cloned the bb.org-overlays source code and tried to build a new dtbo file. I failed. 

When I tried to build the single dtbo file I got the error as below.

When I tried to build all dtbo files I got the error as below.

Would you like to help me to figure it out? Or maybe you can send me the new BB-BBGW-WL1835-00A0.dtbo file to daemo...@163.com.

Thank you very much.

Do it on the Beagle..

Hi  Robert Nelson

Thanks for your response.

I build the new dtbo file on Beagleboard successfully. But when I use this dtbo file on booting I got the error as below.

I could find the eth0 interface in linux but it couldn't work. And the wlan0 works well.

Would you like to help me to figure it out?  Thank you very much.

[daemo...@163.com]

Hi  Robert Nelson

I figured it out. 

Due to the uart3 conflict with the eth0. The uart3 section should be removed from BB-BBGW-WL1835-00A0.dts.

I removed the line 36 and line 143-148 "fragment@2" and line 178-186 "fragment@4" and made the new dtbo file.

It works well.  Thank you very much.
