I am wondering whether Dexed could be ported to Circle, in order to recreate basically an open source equivalent of the TX802 (8 DX7 instances without the keyboard in one box).
## Usage
* Download from [GitHub Releases ](../../releases )
* Unzip
* Put the files into the root directory of a FAT32 formatted partition on microSD card
* Boot in Raspberry Pi 4
## Building locally
E.g., on Ubuntu 20.04:
```
git clone https://github.com/probonopd/MiniDexed
cd MiniDexed
# Recursively pull git submodules
git submodule update --init --recursive
# Install toolchain
wget -q https://developer.arm.com/-/media/Files/downloads/gnu-a/10.3-2021.07/binrel/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf.tar.xz
tar xf gcc-arm-*-*.tar.xz
export PATH=$(readlink -f ./gcc-*/bin/):$PATH
# Build circle-stdlib library
cd circle-stdlib/
./configure -r 4 --prefix "aarch64-none-elf-"
make -j$(nproc)
cd ..
# Build MiniDexed
export PATH=$(readlink -f ./gcc-*/bin/):$PATH
cd src
make -j$(nproc)
ls *.img
cd ..
# Get Raspberry Pi boot files
cd ./circle-stdlib/libs/circle/boot
make
make armstub64
cd -
# Make zip that contains Raspberry Pi 4 boot files
mkdir -p sdcard
cp -r ./circle-stdlib/libs/circle/boot/* sdcard
mv sdcard/config64.txt sdcard/config.txt
rm -rf sdcard/config32.txt sdcard/README sdcard/Makefile sdcard/armstub sdcard/COPYING.linux
cp ./src/*img sdcard/
zip -r MiniDexed_Raspberry_Pi_4.zip sdcard/*
```
