その他情報 †
セットアップ †
- まずはフラッシュストレージの消去から
- Minimal イメージをインストールしたので、ユーザがrootしかいない
groupadd -g 1000 firefly
useradd -g firefly --uid 1000 firefly
mkdir -p /home/firefly
vim /etc/passwd
# rewrite shell from /bin/sh to /bin/bash
visudo
# rewrite admin to wheel
addgroup wheel
usermod -aG wheel firefly
nmcli dev wifi connect xxxxxxxx password xxxxxxxxx
- 当然xxxxは適切なものに置き換える
- ここからはSSH接続で
sudo chown -R /home/firefly
sudo mkdir /mnt/sdcard
blkid
sudo vim /etc/fstab
sudo dpkg-reconfigure tzdata
sudo dpkg -i rclone-*
sudo apt update
sudo apt install tmux git ccache cmake build-essential openjdk-17-jdk-headless libx11-xcb-dev python3-dev python3-pip cron opencl-headers ocl-icd-opencl-dev strace
sudo apt upgrade
pip3 install numpy
秘密鍵/公開鍵 †
OpenCL対応 †
- OpenCL対応
- 発売と同時に焼きこまれたイメージには、OpenCL対応のドライバが入ってない
- で、公式っぽいアカウントから出てる身元不明のドライバを入れてみる（自己責任でね！良い子は真似しちゃダメだよ！）
$ git clone git@github.com:rockchip-linux/libmali.git
$ cd libmali
$ cmake .
$ make
$ sudo make instal
- 全部インストールするのは怖かったので、libOpenCL.soだけ差し替えてみた（自己責任でね！良い子は真似しちゃダメだよ！）
$ git clone git@github.com:rockchip-linux/libmali.git
$ sudo rm /usr/lib/aarch64-linux-gnu/libOpenCL.so
$ sudo cp -p libmali/lib/aarch64-linux-gnu/libmali-midgard-t86x-r13p0-wayland.so /usr/lib/aarch64-linux-gnu/
$ cd /usr/lib/aarch64-linux-gnu/
$ sudo ln -s libmali-midgard-t86x-r13p0.so libOpenCL.so
- soだけ差し替えればOpenCLは動く
- ただし、手元でビルドするためには、openclのヘッダやpcファイルが事実上必須
$ sudo apt install opencl-headers ocl-icd-opencl-dev
Firefly の libmali を使っても、ERROR: The DDK is not compatible とかエラーメッセージが出た場合の対処 †
- どうやら、インストールしただけでは/dev/mali0のパーミッションの問題でGPUにアクセスできなくなるらしい。
- もともと使えなかった
- →libmaliを差し替え
- →使える
- →再起動
- →使えなくなる
- という流れだった。
- 使えたときは、OpenCVのテストプログラムの表示が

- と書いて再起動すれば良いらしい
$ sudo vim /etc/udev/rules.d/99-mali.rules
$ sudo reboot
- 他のライブラリの配置も追々追従しよう
