Android-14 on JH7110

[Peter Yoon]

Now JH7110 can boot-up to Home with Android-14.

Build & Flashing guide is at https://github.com/android-risc-v/device_arv_jh7110

Switched default branch to arv-14,  arv-master is reserved.

Some ART changes are cherry picked from AOSP main branch as shown at :

Is there a way to disable building on Car related packages for now? 

Thanks.

I have not faced such error on building arv-14.

If it's my case, I will try build with fewer -j<n> numbers. It will continue build at 98%.

[Chang Rebecca Swee Fun]

Thanks, that works for me.

Build updated to android-14.0.0_r17 (UQ1A.231205.015)

Hello,
I tried booting Android 14 on a Starfive VisionFive2 board. When booting, I don't get graphics and I don't get an IP address.
I'm interested in which kernel I should use and if there has been an update in the meantime?
I used the following kernel:  GitHub - android-risc-v/kernel_arv at arv-6.4_vs

[Chang Rebecca Swee Fun]

Hi Nikola,

You can try out the prebuilt binary by Peter from: sig-a...@lists.riscv.org | Android-14 on JH7110

For kernel, you can build from https://github.com/android-risc-v/kernel_arv/tree/arv-6.5 . Peter has ported the required patches into this 6.5 branch. It has the HDMI driver available to enable your HDMI display if you have any.

For IP address, i think it could be potential issue because i don't get any IP address on my VisionFive2 board either.

Hope this helps.

Regards,

Rebecca

Hi Rebeca,
Thank you on answer.
When I transfer all images and use following kernel  GitHub - android-risc-v/kernel_arv ,  I have this error in kernel log:

Hello, 

Can we use ADB over USB and has anyone tried it yet?

Thanks.
