TS-7970 USB Device

From embeddedTS Manuals

This SBC includes support to act as a USB peripheral to another system. Remove the "CON EN" jumper to disable the on-board USB serial debug port and connect the USB device port (P1 connector) to the CPU's OTG port. The CPU port is strapped to only act as a USB device. Several devices are compiled into the default kernel. Other devices can be compiled into the kernel by following the compile the kernel section.

USB Serial

modprobe g_serial use_acm=1

This will create the device "/dev/ttyGS0". See the kernel documentation for more information:

USB Ethernet

modprobe g_ether

This provides a "usb0" network interface. This driver simulates an Ethernet network connection between the host PC and the i.MX6.
