TTY not created after connecting to serial port (SAM-BA)
Making sure that the board is connected via USB this can be verified by running
$ lsusb
This sould give an output of all the USB devices you have connected. The Bus and Device values can differ from system to system. The rest of the information is important:
Bus 002 Device 002: ID 03eb:6124 Atmel Corp. at91sam SAMBA bootloader
If this is not the case then you have not configured the hardware correctly. Verify the jumper settings on the board and then unplug the USB cable and reinsert it.
Also make sure that the usbserial module is running. For that enter
$ lsmod | grep usbserial
You should get a line like this in the output
usbserial 35048 0
If the module is missing, Install it. If the module is already associated to some other Controller, say
usbserial 36720 1 pl2303
You need to unload the module first. Once it's already loaded, then doing it manually has no effect. Adding the module manually has to be done before you plug the board in. So....try rebooting :)
The usbserial module has to be added manually (before plugging in the board with):
modprobe usbserial vendor=0x3eb product=0x6124
Now ttyUSB* should be successfully created and can be verified using:
ls -l /dev/ttyUSB*
