Hi eduardofreitas,

Have you considered using a USB hub to connect both the keyboard and a 802.11 adapter to the USB OTG port?

I think that this setup should work since this is what we did for MicroZed at ARM TechCon 2013 in order to connect a keyboard/mouse + USB camera:

Thanks for your help. Looks like it is working the keyboard. But the dongle the xillinux doesn't recognize. Do I need to install some driver? It is this dongle I am using: http://www.ebay.com/itm/Nano-Mini-EDUP-150Mbps-Wireless-WiFi-USB-Network-802-11n-g-b-LAN-Adapter-Card-/121561712315

Thanks very much for every help.

Hello,

I suggest checking the log (i.e. "dmesg" on command problem or looking in /var/log/syslog) for what happens when the USB dongle is inserted.

But odds are that a driver needs to be installed. Note that the driver can be compiled natively on the board's processor. That is, treat Zedboard as a regular computer. The kernel headers are installed in the distribution.

Thanks in advance.

When check the log the give a error: Firmware rtlwifi/rtl8192cufw.bin not available. (when the USB dongle connect).

Do you know how can I fix?

After that, in the top in icon of connection will show all wifi networks or do I need to do something to show the wifi available?

Thanks very much for every help.

best regards,
Eduardo

Hello,

The error kind-of speaks for itself. The driver exists and was loaded, but the firmware file was missing. Odds are that if you Google for the desired file name, you'll find a copy of it. If you put this file as /lib/firmware/rtlwifi/rtl8192cufw.bin in your system, there's a good chance that the Wifi icon will appear on the desktop.

To make life easier for you: The "official" place for Linux firmware is this git repository:

http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git

The desired file can be found at

http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/rtlwifi/rtl8192cufw.bin

Thanks very much. That's error is now fixed.

I am sorry, but I am very new in linux. As you can see in the picture: http://s15.postimg.org/y76u5rvju/20150712_140946.jpg

The driver is install and the firmware are ok. But now there is nothing about wifi, how is it appear? How can I configure and show the wireless network to connect the board to internet?

Thanks for all support.

Best regards,
Eduardo
