microsoft / surface-duo-oss Goto Github PK

Hello

I build the kernel for a Surface Duo 2 and could flash it successfully. Unfortunately, touchscreen shows no response (mice attached over usb-c is working, also the other stuff). What am I missing?

Thanks.

Edit:

Originally I had more problems, because i built QGKI (= no HW working). Now I changed to GKI and only got touchscreen not working.

Edit 2:

Rebuilt and works now.

Running repo sync on a 2021 kernel revision branch causes the following errors:

Then causes a later error:

Do you have a recommended development board？
It seems that only the source code of the kernel can be found on GitHub. Do you open-source the whole Android system?

After following the directions, none of the files created boot through fastboot boot <filename>. I don't want to flash as there's no recovery boot.img if the device doesn't boot, besides boot_b. Is there a step I'm missing to make a bootable kernel?

Error 2 occurs during build/build.sh:
home/repo/kernel/msm-4.14/scripts/selinux/genheaders/genheaders.c:18:0: home/repo/kernel/msm-4.14/security/selinux/include/classmap.h:32:2: error: #error New capability defined, please update COMMON_CAP2_PERMS.

Looking into classmap.h shows that CAP_AUDIT_READ is undefined in classmap.h and its included resources: linux/socket.h and linux/capability.h

The issue does not occur after commenting out lines 31 to 33 in msm-4.14/security/selinux/include/classmap.h

Hello,

I am trying to build a bootable kernel for the surface duo 1 using this guide. So far the building process completes without any errors and produces an Image file, dtbo.img, some *.ko files as well as a few *.dtbo artifacts.

When flashing with Anykernel3 for example (or boot.img via mkbootimg.py), the device seems to boot, but does not have hardware support. It is stuck at "phone is starting" and restarts after a few moments. I guess drivers are missing somehow.

How can I add these pls? I had a similar experience when building for SD2 QGKI, but there it could be solved by just building the GKI version.

Thanks in advance!

Best regards
