==Create System Image==

===Host System Requirements===
At least Debian 12 (bookworm) or Ubuntu 22.04. with Memory >= 16GB and disk space >= 100GB.

===Build Debian/Ubuntu system image (mainline kernel)===
Check README in https://github.com/photonicat/rockchip_rk3576_linux_mainline for building system image.

===Build OpenWRT===
====Host System Requirements====
Debian 11 (bullseye) or Ubuntu 20.04, other distributions may work but not tested.

====Compiling Requirements====
Please a NORMAL USER, not root

On Debian/Ubuntu systems, install the packages:
<pre>
sudo apt update

libpython3-dev qemu-utils rsync scons squashfs-tools subversion swig texinfo uglifyjs upx-ucl unzip \
vim wget xmlto xxd zlib1g-dev
</pre>

====Get repo files====
Get repo files from Github (non-root user):
<pre>
git clone https://github.com/photonicat/rockchip_rk3568_openwrt.git
cd rockchip_rk3568_openwrt
</pre>

===Config build target===
Run the command below:
<pre>
./scripts/feeds update -a
./scripts/feeds install -a
cp ./configs/photonicat2_base_defconfig .config
</pre>

===Build system image===
Run the command below:
<pre>
make
</pre>
The output path is <code>bin/targets/rockchip/armv8/</code>, system image will be named like <code>photonicatwrt-25.02.0-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat2-squashfs-sysupgrade.img.gz</code>

===Edit your menuconfig (Optional)===
<pre>
make menuconfig
</pre>

save and re-run build process again.

IPKs will be under: <pre>bin/targets/rockchip/armv8/packages/</pre>

===Build your own package, modules on OpenWRT (Optional)===
Use <pre>make menuconfig</pre> to select <pre><M> package_name</pre> for your desired package(s).
If you want to include your own packages to system image, see OpenWRT official documents https://openwrt.org/docs/guide-developer/packages for help.

===Install pcat-manager-web on OpenWRT (Optional)===
If you want to use original Web management tool, you should change the port used by luci to 8080, edit /etc/config/uhttpd on device, change
<pre>
list listen_http '0.0.0.0:80'
list listen_http '[::]:80'
list listen_https '0.0.0.0:443'
list listen_https '[::]:443'
</pre>
to
<pre>
list listen_http '0.0.0.0:8080'
list listen_http '[::]:8080'
list listen_https '0.0.0.0:8443'
list listen_https '[::]:8443'
</pre>

Then install pcat-manager-web on device:
<pre>
cd /tmp
wget https://dl.photonicat.com/repos/photonicatwrt/photonicat2/volatile/pcat-manager-web_2.0.1-27_aarch64_generic.ipk
opkg install pcat-manager-web_2.0.1-27_aarch64_generic.ipk
</pre>

Reboot your device to apply changes.

==Flash system images to the onboard eMMC==
Prepare update tools and files:
<pre>
git clone https://github.com/rockchip-linux/rkdeveloptool.git
cd rkdeveloptool
sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf
aclocal
autoreconf -i
autoheader
automake --add-missing
./configure
make
wget https://dl.photonicat.com/images/photonicat2/RK3576_MiniLoaderAll.bin
</pre>

Refer: [[Photonicat_快速上手#4G/5G版本按键功能定义]] to enter the firmware update mode, use A-to-A cable to connect USB OTG port to PC, and use the command below:
<pre>
gunzip photonicatwrt-25.02.0-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat2-squashfs-sysupgrade.img.gz #Replace file name with the one you get indeed.
sudo ./rkdeveloptool db MiniLoaderAll.bin
sudo ./rkdeveloptool wl 0 photonicatwrt-25.02.0-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat2-squashfs-sysupgrade.img
sudo ./rkdeveloptool rd
</pre>

==How to modify your own version of kernel for OpenWRT==
Compile <code>rockchip_rk3568_openwrt</code> with above steps.

Modify:
*DTB: https://github.com/photonicat/rockchip_rk3568_openwrt/blob/master/target/linux/rockchip/files/arch/arm64/boot/dts/rockchip/rk3576-photonicat2.dts
*kernel patches: (we need to add/ modify your version of kernel patches into this dir and recompile): https://github.com/photonicat/rockchip_rk3568_openwrt/tree/master/target/linux/rockchip/patches-6.12

Recompile and done.
