Mainline kernel (via Precomposed Configurations) For details, you can refer to our manual build howto. Now you can compile the kernel and modules. Note: You need to select both "Inventra Highspeed Dual Role Controller" and "NOP USB Transceiver Driver" before the required "Allwinner (sunxi)" option ( CONFIG_USB_MUSB_SUNXI) becomes available. USB Gadget functions configurable through configfs

Inventra Highspeed Dual Role Controller (TI, ADI, AW. The RNDIS gadget with configfs requires a number of menuconfig options being enabled: (Instructions below were tested on A20 with kernel 5.9.0.) The configfs approach allows you to configure the device dynamically from user-space.Thereby, additional configuration needs to be done to bring up the gadget compared with precomposed configurations.
