Android11 build for CM3 Problem

Hi:
I refer to the website “https://wiki.radxa.com/Rock3/Android11”.Problems when Building the kernel.
arch/arm64/Makefile:203: recipe for target ‘rk3566-rock-cm3io.img’ failed
make: *** [rk3566-rock-cm3io.img] Error 1

Please provide more log with make -j1 command.

I used to follow “Use all-in-one build script” {
1 source build/envsetup.sh;
2 lunch rk356x_rock_cm3_r-userdebug;
3 ./build.sh -UACKup}, so the previous error occurred.}
But,Now With build cmd “make -j $(nproc)”,Build is OK! Thanks!

arch/arm64/Makefile:203: recipe for target ‘rk3566-rock-cm3io.img’ failed occured
make: *** [rk3566-rock-cm3io.img] Error 1
How can I respond?

Continue to compile AOSP, and follow the instructions to make images and follow-up steps.
