前回noteの続き

Cortex-R5の実行が目的であるが、よいサンプルはXilinxのQEMUにある。以下のURL

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/822312999/Building+and+Running+QEMU+from+Source+Code

にしたがってまずチュートリアルを実行できることを確認する。

環境

WSL 2, Ubuntu 22.04.2 LTS

QEMUのビルド

cd $WORKSPACE
git clone https://github.com/Xilinx/qemu.git
cd qemu
git checkout tags/xilinx-v2023.1
git submodule update –init dtc
mkdir build
cd build
sudo apt-get update
sudo apt install libglib2.0-dev libgcrypt20-dev zlib1g-dev autoconf automake libtool bison flex libpixman-1-dev build-essential gdb ninja-build
../configure --target-list="aarch64-softmmu,microblazeel-softmmu" --enable-fdt --disable-kvm --disable-xen --enable-gcrypt
make -j16

QEMU devicetreeのビルド

cd $WORKSPACE
git clone https://github.com/Xilinx/qemu-devicetrees.git
cd qemu-devicetrees
make

examplesのDL

cd $WORKSPACE
git clone https://github.com/Xilinx/qemu-ug-examples

examplesの実行(bare_metal_r5)

cd $WORKSPACE/qemu-ug-examples/BareMetal_examples/bare_metal_r5
./test.sh $WORKSPACE/qemu/build/aarch64-softmmu $WORKSPACE/qemu-devicetrees/LATEST/SINGLE_ARCH

結果

Hello WorldHello Test Passed
Successfully ran UartPsv Hello World Example

examplesの実行(bare_metal_r5_zynqmp)

cd $WORKSPACE/qemu-ug-examples/BareMetal_examples/bare_metal_r5_zynqmp
./test.sh $WORKSPACE/qemu/build/aarch64-softmmu $WORKSPACE/qemu-devicetrees/LATEST/SINGLE_ARCH
