Made this bsp/sdk because the beta wich is on the site don't makes a image wich you can flash and boot from sd/emmc
and while mainline is cool a working bsp/sdk makes it more complete for me
I looked how raxda and firefly made their bsp/sdk and made a custom one for the Quartz64
used some scripts of them and adjusted so they work to build a image
Most sources are from rockchip and the just 2 or 3 comes from other sources (from firefly: rawimg script, qsetting and camera_engine_rkaiq package)
So i tried to keep it some kind rockchip original and those packages were not on the rockhcip site or other open places so if it is a problem i can remove them
The bsp/sdk builds a buildroot ,debian or yocto distro wich you can flash on a sd/emmc or rockchip images to do it the difficult way
the hardest part was to get the right revisions to make some packages work
The bsp/sdk has 2 kernel options kernel 4.19.19 or 5.10.66 from rockchip sources
the 4.19 is common used kernel for the rk3566/68 bsp/sdk kernel and it has
working hdmi,lan,usb,wifi,gpu and npu
inside this SDK you will need to include this header to dts file
