在公司拿到了一个测试用的板子，tb96-ai + rk3399pro.
[toybrick@toybrick]~% cat /proc/device-tree/compatible
rockchip,rk3399pro-toybrick-96ai-linuxrockchip,rk3399pro
系统是fedora28.
设置ssh
连入键盘和鼠标, 编辑/etc/ssh/sshd_config, 将
#Port 22
取消注释, 然后
sudo systemctl enable sshd
设置不启动GUI
为了减少CPU占用嘛.
systemctl set-default multi-user.target
要恢复的话
systemctl set-default graphical.target
设置shell自动登录
系统在登录后才会连接wifi，不知道为啥。
设置shell自动登录：参考stackchange
编辑/etc/systemd/logind.conf, 将#NAutoVTs=6改为NAutoVTs=2.
然后运行
systemctl edit getty@tty1
, 输入
[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin toybrick --noclear %I 38400 linux
启用getty@tty1.service:
systemctl enable getty@tty1.service
然后重启.
mirror设置
配置文件在/etc/yum.repos.d. 文件参考github.
编辑/etc/dnf/dnf.conf, 在最后加入fastestmirror=1.
软件升级
升级系统： fedora wiki。 只支持跨两个版本，所以我升级到了fedora 30. (不知道会不会break原本的驱动和库
当时存储还不够(16G存储), 我删掉了~/.cache, python package, qtcreator才升级完成.
首先刷新一下:
sudo dnf upgrade --refresh
然后重启.
安装dnf-plugin-system-upgrade:
sudo dnf install dnf-plugin-system-upgrade
下载升级软件包:
sudo dnf system-upgrade download --releasever=30 --allowerasing --skip-broken
升级前需要先将locale设置为en_US, 不然会出现终端方块的情况.
sudo localectl set-locale LANG=en_US.utf8
升级:
sudo dnf system-upgrade reboot
安装软件
sudo dnf makecache
sudo dnf install vim ncdu zsh tmux qtcreator -y
chsh -s $(which zsh)
qtcreator是之前卸载的.
设置防火墙
针对ftp服务（vsftpd）：
sudo firewall-cmd --add-port=21/tcp
sudo firewall-cmd --runtime-to-permanent
查看允许的端口
sudo firewall-cmd --list-ports
参考：fedora文档
其他
查看开机启动时的错误:
systemctl --state=failed
待解决
iwd无法使用
查看iwd启动程序:
systemctl cat iwd
是/usr/libexec/iwd.
运行时的错误:
[toybrick@toybrick]~% /usr/libexec/iwd
DES support not found
No CBC(DES3_EDE) support found, certain TLS connections might fail
No Diffie-Hellman support found, WPS will not be available
No keyring restrictions support found.
No asymmetric key support found.
TLS based WPA-Enterprise authentication methods will not function.
Kernel 4.20+ is required for this feature.
The following options are missing in the kernel:
CONFIG_CRYPTO_USER_API_SKCIPHER
CONFIG_ASYMMETRIC_KEY_TYPE
CONFIG_KEY_DH_OPERATIONS
CONFIG_CRYPTO_ECB
CONFIG_KEYS
CONFIG_CRYPTO_CBC
CONFIG_CRYPTO_DES
CONFIG_CRYPTO_DES
CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE
CONFIG_PKCS7_MESSAGE_PARSER
CONFIG_X509_CERTIFICATE_PARSER
CONFIG_PKCS8_PRIVATE_KEY_PARSER
The following optimized implementations might be available:
CONFIG_CRYPTO_DES3_EDE_X86_64
CONFIG_CRYPTO_DES3_EDE_X86_64
好像没有办法升级内核.
