Where can I get the build script of radxa rock 3a

Is there a mirror for ubuntu18? and with pre-built rknn-toolkit?

Followed this to a tee, twice on two different systems, and could not get it to work.

Also tried gnome-core to get wayland instead of plasma/KDE, and switched from lightdm to gdm3, but it seems that using xserver-xorg-core/bullseye does not work at all.

xserver-xorg-core/rockchip-bullseye at least allows it to work with the existing drives (removing the ld.so.conf.d entry).

This is a request and not a bug.

Request is for CLI version added to the RBUILD using standard Kernel Fully Preemptive Kernel (RT) option. So far my research indicates the kconfig option is PREEMPT_RT.

Research has indicated as of Version 5.10 of the vanilla Linux Kernel can be configured as a low-latency version as the mainline Kernel has accepted multiple merge requests from the Preempt-rt patch team.

This request is not for the Preempt-rt patches to be applied to the standard Linux Kernel. Just to enable the kconfig option PREEMPT_RT that the standard Linux Kernel has.

This is a request and not a bug.

All Linux Kernel debug options should be turned off to reduce random amount of response time and variations in response time behaviour of Linux Kernel should be separate request and linked to this request as in itself . Kernel debug code adds varied amounts of delay, at times significant delays, due to debug code added to Linux Kernel processing. Eliminating Linux Kernel debug code removes the varied and at times significant time the Linux Kernel takes to process and reduces the amount of data log to log files. As well the Linux Kernel will be smaller and take up less memory footprint.

If desired and makes sense a debug version of Linux Kernel can be included with option to boot the debug version of the Linux Kernel via the configuration file read at boot time that amongst other options contains any Device Tree files/overlays to be loaded.

This SBC was released 2021-08-25.... Yet still no actual GPU HW acceleration in any officially release RADXA images.
Is there a specific reason we have no GPU support?

Guys GPU and VPU of the ROCK-3A board don't work and graphic and video processings are performed on CPU that is highly loaded and at very low framerate
Seeed Studio claims that their device based on RK3568 model LinkStar-H68K supports GPU and VPU accelerations and supports 4K@60fps H.265/H.264/VP9 video decoding and 1080@60fps H.265/H.264 video encoding
I tried to run images for LinkStar-H68K on ROCK-3A but without success.
Could you integrate video acceleration in RCK-3A images or help me to run LinkStar-H68K images on my ROCK-3A?

No hardware accelerated video decoding and encoding and video cant pe played and written
I installed video codecs and VLC but there is no video acceleration obviously because there is no video driver
Without video acceleration board is completely useless
