CONFIG_USB-Build Support for Host-side USBĢ. 元.14.28_1.0.0-ga, 03/2015 has a useful section on the USB driver options, which helped me get it working, e.g.: 1. The i.MX 6 Linux® Reference Manual Document Number: IMX6LXRM Check USB ID line is not pulled low either by hardware or pin mux in device tree file.If the im圆 doesn't appear on USB during the second stage, and the message ' UTP: Waiting for device to appear' is shown on the debug UART, check the following:.With this tool you'll see the im圆 appear as vid=15A2, pid=0054 during the first stage (when transferring U-Boot, Kernel and File system), and then you'll see this disappear and reappear as vid=066F, pid=37FF during the second stage (when the mfgtool kernel is booted). Install and use USB View ( USBView - Windows 10 hardware dev) to see how the im圆 is appearing on the PC's USB bus. I've had a long and difficult struggle to get a working Mfgtool build from Yocto source (Fido) for custom im圆 hardware.
