Why is Arduino not defined in Linux?

Question

linux

So I connected arduino uno to Radxa Rock (soldier, core 3.0.36+)
Dmesg:
[ 3.089004] usb 2-1.4: new full speed USB device number 5 using usb20_host
[ 3.192434] usb 2-1.4: New USB device found, idVendor =2a03, idProduct=0043

[ 3.192816] usb 2-1.4: SerialNumber: 8543830313335190C192 It is
necessary that the Arduino serial port appears in /dev. On a computer, it looks like ttyACM0, but here I don’t even see it:

How to find it then?

Answer 1

means there is no firewood for the series. look on a large PC with the lsmod command what driver is needed - and look for / collect it for Radxa Rock

Answer 2

I would read detailed instructions for setting up Arduino in Linux
