[ROM][Android9.0][RockPI 4A/B] Android P firmware released

#11

You may need to modify the source of systemui

#12

I am connected now, but this command does not work.

PS C:\adb> ./adb shell am start com.amazon.avod.thirdpartyclient/.LauncherActivity
Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.amazon.avod.thirdpartyclient/.LauncherActivity }
Error type 3
Error: Activity class {com.amazon.avod.thirdpartyclient/com.amazon.avod.thirdpartyclient.LauncherActivity} does not exist.

I have also a problem with playstore.
When I click the “Search function”
the search bar appears and disappears in a second

and kodi , installed from the play store,crashes directly aftervstart

Greetings

You need install it first.

Hi,
Can I get a root? And how can I do this?

#15

Radxa can built firmware with Magisk enabled.
Then you can patch your boot.img with MagiskManager(or a patched boot.img can be directly used for firmware image) to have root.

你好，请问编译的话如何编译？
这样编译出来的是TV版的
lunch rk3399_box-userdebug
make -j$(nproc)

如果我想编译成Tablet版的，是按下面这个方法么
lunch rk3399-userdebug
make -j$(nproc)
但是我编译之后，貌似启动不了，一直卡Android，是哪里做错了么

#18

Unfortunately the 9.0 P image does not seems to support the RasPi Cam (the 7.1 image did!). Hope, this will be added soon?

Has anyone tried to use an USB (UVC) camera with the 9.0 image?

#19


I will check.Thanks.

#20


lunch rk3399-userdebug, 我已经找到问题了,等我更新吧.

#21


现在没问题了,你更新试试

#22

多谢多谢多谢多谢，问题已解决🙏

#25

New version released.

#26

Hello,

why the support for 2560x1440 resolution is disabled? I have it on first start on the “erase” screen but it switch back to 1920x1080 after reboot. The May image was fine.

Regards.

#27

Hello,

another question. I must say the cpu runs very hot (with big heatsink) on android 9 compared to the linaro image. Is there is no power saving or something an the android 9 image?

Regards.

#28

Android 9 RK filters 2560x1440 by default.
Reference: /system/usr/share/resolution_white.xml
We will try to add in later versions.

#29

linaro image? Can you elaborate on it?
Do you think Android 9 is hotter than Android7(all other things being equal)?

#30

I was noticing some increased CPU load (and heat) from com.rockchips.mediacenter. Since I don’t use it, I just disabled it pm disable com.rockchips.mediacenter and temperature went down. Now idling at;

# cat /sys/devices/virtual/thermal/thermal_zone?/temp
36875
36250
2600

Edit for those trying to compare temperatures… that’s a Rock960C with a modified AB heat sink case, so it won’t be directly comparable to RockPi4: https://store.vamrs.com/collections/rock960/products/metal-case-for-rock960

@Lili :

I’ve been finding it to be a problem that the console disconnects early in the boot.

The kernel is configured to put the console on ttyFIQ0;

# cat /proc/cmdline

But there is no such device;

# ls /dev
__properties__ cg2_bpf         dri            graphics    iep         loop-control     network_latency    ptmx   rtc0      tty   uhid          vpu_service

block          cpuctl          fscklogs       i2c-0       keychord    memcg            opteearmtz00       rfkill socket    ttyS3 usb-ffs

Based on the u-boot configuration, it looks like it should be on 0xFF1A0000, which is ttyS2, so probably should be parameters as;
console=ttyS2,1500000n8 androidboot.console=ttyS2

#32

no worry, i will check this with some future power measurements because the feeling of heatsink says nothing but here are some snapshots of the temperature outputs:
