System setup¶

We must create three services on the device

init_system service¶

Create file /etc/systemd/system/init_system.service

[Unit]
Description=Init python script
After=network.target

[Service]
WorkingDirectory=/data/firmware/htdocs/python
ExecStart=/usr/bin/python3 /data/firmware/htdocs/python/init.py

[Install]
WantedBy=multi-user.target

lemcoplayer service¶

Create file /etc/systemd/system/lemcoplayer.service

[Unit]
Description=Application startup script
After=network.target

StartLimitIntervalSec=60
StartLimitBurst=5

[Service]
Type=simple
Restart=always
RestartSec=7
ExecStartPre=/bin/sleep 1
ExecStartPre=systemctl stop externalplayer
ExecStartPre=/bin/sleep 1
ExecStartPre=-modetest -M rockchip -w 57:zpos:1
ExecStartPre=-modetest -M rockchip -w 73:zpos:0
ExecStartPre=echo 0 >/sys/class/graphics/fb0/blank
ExecStartPre=-/data/firmware/htdocs/python/init.sh
#ExecStartPre=echo 0 > /sys/bus/usb/devices/3-1/authorized
#ExecStartPre=echo 1 > /sys/bus/usb/devices/3-1/authorized

[Install]
WantedBy=multi-user.target

externalplayer service¶

[Unit]
Description=Application external player script
After=network.target

StartLimitIntervalSec=60
StartLimitBurst=0

[Service]
Type=simple
Restart=always
RestartSec=7
Environment="GST_MPP_DEC_DEFAULT_IGNORE_ERROR=0"
Environment="GST_VIDEO_FLIP_USE_RGA=1"
Environment="GST_VIDEO_CONVERT_USE_RGA=1"
ExecStart=/data/firmware/externalplayer

[Install]
WantedBy=multi-user.target

Then execute:

systemctl daemon-reload
systemctl enable init_system
systemctl enable lemcoplayer
systemctl enable externalplayer
