AW: i.MX6ul USB serial downloader and Barebox

[Patrick Schneider <patrick.schneider@bhtronik.de>]

Hi Sascha,
thanks for the reply.
It seems that I am lacking something in the usb configuration. I am always getting:

couldn't find an available UDC
usbgadget: No such device

$ fastboot devices -l

Delivers nothing on my windows host side.
Before I proceed, wouldn't it be also possible to just plug a usb-stick and copy rootfs and barebox.bin from there?
Unfortunately

$ usb

Also doesn't recognize my plugged in usb-stick.
The USB port functions normally under linux itself. 

Regards,
Patrick
