The NXP/Freescale Vybrid BSP (since V2.4 Beta 1) and the i.MX BSP (since V2.5 Beta 2) use the USB Gadget ConfigFS to configure the USB peripheral port. Linux NXP/Freescale Vybrid/i.MX7/i.MX6ULL/i.MX6/i.MX8/i.MX8X based Modules This prevents you from updating the bootloader over this mechanism. Note that ums currently can only export the user area of an eMMC but not its boot areas. Assuming you have our regular BSP installed on an eMMC based SoM the following block devices will also appear and possibly mounted: $ lsusb On the host connected to the SoM you will now see the following USB device. UMS: LUN 0, dev 0, hwpart 0, sector 0x0, count 0x1d5a000 Note that with CTRL+C you can abort the operation and regain control over U-Boot. The following exports the eMMC on SoMs with an eMMC or the SD card on the SoMs with raw NAND. This common U-Boot version configures the USB peripheral device identification using the Toradex vendor ID and product ID. Since BSP V2.4 all modules use the same U-Boot version 2015.04. Both USB functions conform to standardized USB classes. With recent versions we successfully tested ums (User Mode Storage) and dfu (Device Firmware Upgrade).
U-Boot's CONFIG_USB_DEVICE config symbol allows for U-Boot to provide USB peripheral mode support. While it is still a good starting point, for newer BSP versions some commands may be obsolete or not working anymore. Warning: this article has been written with our BSP Layers and Reference Images for Yocto Project 2.8 in mind. 1d6b:0104 Linux Foundation Multifunction Composite Gadget). For better out-of-the-box experience the standard images typically use the default Linux USB product/vendor ID (e.g. While it is possible to use the driver delivered with Windows a custom inf file still needs to be provided. CDC ACM for Microsoft Windows) even for standard USB classes.

Some platforms need device dependent and certified drivers (e.g. 0x4000 + 12 = 0x400c (the product identifier is the first 4 digits of the Toradex Product Number, e.g. The USB Product ID is the sum of an offset of 0x4000 and the hexadecimal representation of the product identifier, e.g. Toradex has its own vendor ID (0x1b67) and assigns a product ID for each Colibri and Apalis product which you as a customer can use too. USB peripheral devices need a vendor and product identification. Depending on the Linux kernel version provided by our BSP a different level of USB peripheral functionality and API is available. Later in Linux 3.10 a similar functionality also landed in the upstream kernel which now allows configuring USB gadgets through configfs (the USB Gadget ConfigFS).

The Android variant of the Linux kernel added functionality allowing easy switching between USB functions using sysfs. The Linux USB gadget drivers received increasingly more attention and have evolved over time, especially since Android appeared. Traditionally the USB function had to be chosen at Kernel compile time (e.g. This API abstracts the USB peripheral controller hardware as well as offers hardware neutral routines which allow to implement USB functions (e.g. On Linux USB peripheral mode is supported through the Gadget API.

On Apalis modules a full OTG port (USBO1) is provided which makes use of the OTG ID pin using the USBO1_ID signal to determine its role and additionally the VBUS pin using the USBO1_VBUS signal to determine the actual connection status thereof allowing suspending the USB complex if not connected.

On the other hand VBUS is also connected to the Colibri USBC_DET signal (usually via a diode) allowing driver software to monitor and subsequently change the role. If a USB Micro-B OTG cable is used (which connects the ID pin to ground) the circuit on the carrier board automatically enables driving +5V onto VBUS in order to provide power to USB devices as required by a host. By default the port is in peripheral mode. On Colibri modules the client port (USBC) is usually connected to a dual-role capable controller. The dual-role controllers often also support the OTG (On-The-Go) specification which defines a host negotiation protocol allowing two devices to negotiate for the role of the host. However, embedded systems often have multiple USB controller supporting host or peripheral roles or supporting both roles on a single controller (dual-role controller). Most PCs support USB host mode exclusively. The bus can only have one USB host connected all other devices need to be in USB peripheral mode.

The USB (Universal Serial Bus) standard specifies two roles USB host and USB peripheral (also known as USB function, USB peripheral device or sometimes just USB device).
