ElectronAsh / spu_test

SPU debugging via AXI on MiSTer, for Laxer3A's PSX SPU core.

Easier method for installing the GCC ARM toolchain, as it sets up the paths for you.

It works fine for spu_test, but I'm not sure if the latest GCC ARM version may cause issues when compiling Main_MiSTer. (ElectronAsh).

sudo apt-get update
sudo apt-get install libc6-armel-cross libc6-dev-armel-cross binutils-arm-linux-gnueabi libncurses5-dev build-essential bison flex libssl-dev bc
sudo apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf

This is the older method. Please skip this for now if the above method works for you.

wget -c https://releases.linaro.org/components/toolchain/binaries/6.5-2018.12/arm-linux-gnueabihf/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz -C /opt
export CC='/opt/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc'
export PATH=$PATH:/opt/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin
export PATH=$PATH:/opt/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/lib

To compile spu_test...

arm-linux-gnueabihf-gcc spu_test.c -o spu_test

To copy spu_test to the MiSTer SD card root via ssh/scp, then execute spu_test...

./comp.sh

(replace the IP address in the comp.sh script with the IP from your MiSTer main OSD menu.)

The core MUST have AXI bridge support enabled, else running spu_test will likely crash the HPS, and it will self-restart after 10-20 seconds.
