USB-OTG on Zedboard running Arch Linux


Hi, I'm running Arch Linux (https://archlinuxarm.org/platforms/armv7/xilinx/zedboard) on Zedboard and I'd like to use the OTG-USB as a host, but my Zedboard doesn't seem to detect the device plugged in (I've tried a USB flash drive). What are your suggestions? I've followed the instructions on http://zedboard.org/sites/default/files/documentations/GS-AES-Z7EV-7Z020-G-V7-1.pdf , but Zedboard just won't see the device.

It could be the device tree, can you provide the node for the USB controller?

I'm not familiar with the archlinux docs and images you are using, so I can't really say off the top what is wrong. You could use the Petalinux BSP (which includes pre-built images) from Xilinx as an example of a working linux system with USB host. That could help you pinpoint what is wrong in the archlinux image.
