Hello everyone!
I'm new to OpenWrt and very excited to use it. 
Because this will be my first time using OpenWrt I have some newbie questions.
The hardware I want to use:
Raspberry Pi Compute Module 4 4GB RAM, 16GB Flash, WLAN + BT
WaveShare Dual Gigabit Ethernet 5G/4G Base Board
Later adding:
LTE modem / SIM card
Would you be so kind and give me a hint which packages/drivers I need? Where can I read something about it?
At first I need to follow the instrucions by Waveshare. I can use the eMMC version, but is this good in terms of backups? I think a backup of an sd-card is easier, what would you recommend?
Do I then need other packages?l
Packages I found out I could need are:
- usb-modeswitch
- kmod-mii
- kmod-usb-net
- kmod-usb-wdm
- kmod-usb-serial
- kmod-usb-serial-option
- kmod-usb-serial-wwan
Thank you a lot!
