Anbernic RG35XX H Test program

For Knulli OS at the moment, a testprogram to learn making programs for the Anbernic RG35XX H. Currently using the Knulli sysroot but not any docker. I dont really like to use docker.

Support for stock os might also be cool.

Building

Tricky, basicly I got the knulli toolchain and instead of doing this the docker way, we extract and change PATH and point everything to it to compile our program, seems to work. might be dangerous. Here be hacker dragons.

wget -c -O aarch64-buildroot-linux-gnu_sdk-buildroot.tar.gz https://github.com/knulli-cfw/toolchains/releases/download/rg35xx-plush-sdk-20240421/aarch64-buildroot-linux-gnu_sdk-buildroot.tar.gz

tar -xzf aarch64-buildroot-linux-gnu_sdk-buildroot.tar.gz

then go set some variables:

export PATH=/home/codeasm/games/anbernic/SDK/knulli-sdk/build/aarch64-buildroot-linux-gnu_sdk-buildroot/bin:$PATH
export SYSROOT=/home/codeasm/games/anbernic/SDK/knulli-sdk/build/aarch64-buildroot-linux-gnu_sdk-buildroot/aarch64-buildroot-linux-gnu/sysroot

export CC="aarch64-buildroot-linux-gnu-gcc"
export CXX="aarch64-buildroot-linux-gnu-g++"
export AR="aarch64-buildroot-linux-gnu-ar"
export LD="aarch64-buildroot-linux-gnu-ld"
export STRIP="aarch64-buildroot-linux-gnu-strip"
export PKG_CONFIG_PATH="$SYSROOT/usr/lib/pkgconfig"
export PKG_CONFIG_SYSROOT_DIR="$SYSROOT"

Yes, I use a script for this, might publish, need to research if any of the above is actually needed.

run this to build:

make CC=$CC CXX=$CXX AR=$AR LD=$LD STRIP=$STRIP PKG_CONFIG_PATH=$PKG_CONFIG_PATH PKG_CONFIG_SYSROOT_DIR=$PKG_CONFIG_SYSROOT_DIR VERBOSE=1

For other distro's, I asume you need their well respected SDK/Toolchain, as they may link differently to stuff.

Installing and Running

Copy the TestApp to the /userdata/roms/tools/Tester folder (create the Tester folder) and copy TestApp.sh to /userdata/roms/tools/ After you rescan for new games and apps, it should show up as TestApp. Now just run the program, quit by pressing and releasing button 11/16 (F) on the Anbernic RG35XX H.

An installer and easier instalation would be cool. TBD.

helpfull extra commands:

scp TestApp root@192.168.2.19:/userdata/roms/tools/Tester/
scp Tester/Tester.sh root@192.168.2.19:/userdata/roms/tools/TestApp.sh

without security turned on, the password is linux for the root user. Check the security page under system settings to see the root password if you enabled more security (which you should).

Todo

• Replace the original m8c square box with anything else
• Make whatever object will be there, react to the joystick input
• color, textures
• Audio
• Replace or get permision for the included fonts.

Thanks

• laamaa - Jonne Kokkonen for your m8c code I butchered and basicly took as a SDL2 template.
• jamesMcMeex - James, Thanks for your H700 fork, which I adapted for this project. Your code worked seamlessly on both the stock OS and Knulli OS.
• knulli - Thanks team behind Knulli, for your amazing handheld distro, which is based on Batocera. It makes the handheld so much cleaner to run and play games on. And lets not forget about the toolchain you folks publicly share too.
• Trash80 for their awesome music, and apparently font. Hope for now its ok I kept the font in the sources.
• acmeplus - development help how to launch an application and revealed it was a user error, not SDL2 lib issue
• chrizzo-hb - Christoph Greulich at the Knulli Discord for suggestions where to look for to properly start my app.
• And any other people in my life who support me, or find me a bit annoying. Thanks for sticking with me and replying to my silly questions or messages.
