BUILD CUSTOM SDK

[Randomuser]

Thank you for this. It makes things much more straightforward.

Is there a chance you could write a similar guide how to build a custom Android image?


Also, if we are cloning the entire sdk with repo tool does this mean the 35GB Linux BSP/SDK file is essentially useless/outdated?


Also, it failed on my Ubuntu 20.04 with:

Code:

Running build_uboot succeeded.
Skipping build_loader for missing configs:  RK_LOADER_BUILD_TARGET.

Does anyone know how to proceed? I searched for Quartz_defconfig, but it is not in any subdirs.

Edit: I can answer my own question for anyone having the same issue.

It seems the file: 

Code:

device/rockchip/rk356x/pine64-rk3566-ubuntu.mk

Has this line:

Code:

export RK_KERNEL_DEFCONFIG=Quartz64_defconfig

it needs to be changed to this:

Code:

export RK_KERNEL_DEFCONFIG=Quartz64_linux_defconfig

Then it proceeds with kernel build.
