Linux/J6EVM5777: Problem with IPv6 over USB NCM interface

Alan Lee73

Part Number: J6EVM5777

Tool/software: Linux

This question is a continuation from a previous thread on IPv6 issue on Android OS --> https://e2e.ti.com/support/arm/automotive_processors/f/1020/p/657820/2447091#2447091

We are still using 6AM.1.3-P1 but I recently tested 6AO.1.1 for a possibility of migrating to the latest OS.

I have flashed the pre-built binaries from TI and did a simple ping6 test using the TI Jacinto 6 board and my laptop using a crossover ethernet cable as was done previously.

I'm still not able to ping using IPv6 between the devices.

It does work, however, when I use a shared access point in between.

But I need it to work over a direct connection which eventually will be used for CarPlay USB NCM communication using IPv6.

I wonder how you were able to verify this problem was fixed with the internal version before 6AO build was released by TI.

Thanks,

Alan

Hi Alan,

I will try on 6AO.1.1 and update you. Last time I tested when O MR1 was private.

Did you try this on Ethernet port which was automatically brought up by Android?
(Android brings up one of the two Ethernet ports by default at boot time)

Yes. I used eth0.

Hi Alan,

I see the same behavior as you on 6AO.1.1 release.
Direct connection ping6 doesn't work, but through a network it works.

Will double check the private build once gain.

Hi Alan,

I was unable to find the private builds. I have to check if some one else in team has.

Have you tried posting this behavior on any Google forums?

No. I have not tried posting to Google forum as I don't know what changes TI is making to the vanilla AOSP.

Which forum do you suggest I post this to?

Also if you do find the old private build and IPv6 works, are you going to try to figure out what is different between the two builds?

Thanks,

Alan

Hi Alan,

For the most part we don't touch any common AOSP code , we add TI HAL layers to AOSP code base.

Here maybe?

HI Vishal,

I think if there is nothing you can do on this problem and would defer to Google to handle the issue, we can close this.

Thanks,
Alan
