@anon39001862 Hi. Does it support Vulkan 1.2 or 1.3?
And how can I unpack this img file? I tried to use imgRePackerRK_107h_test.zip, but it says Unsupported ChipID.
the images are in gpt format so you can flash them just with a dd or etcher etc
Why would you want such an old kernels version.
Android 12 is based on 5.4 and we are about to enter the 6.0 series. Back porting all the Arm and Rockchip changes is quote time consuming. Android 12.1 is running a newer kernel.
who said i want a old kernel version ?
rk3566 is 4.19 downstream and works for me
and 5.10 works etc
and go ahead with mainline i wont stop you
hello, can you share how to download android12 sdk source code for 5B?
Dears I got myself an Intel 7265 WF/BT card as listed/recommended under wiki.radxa.com/Rock5/hardware/wifi. This works well under Linux by placing Intel’s firmware blob from wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7265-ucode-25.30.14.0.tgz under /lib/firmware and reloading iwlwifi kernel module. I noticed wifi is not working for me using any of the Android builds for this board. Can anybody point me in the right direction the best way to go about this? Can I avoid manually building Android, instead, placing above mentioned firmware from Intel (which is for Linux) under something like \system\etc\firmware\wifi or persist location? Presumably having root access (haven’t tried) or adb?
