I'm trying to add wireless usb support to my imx233. My card is and EnGenius with chipset rt2870. I have selected the driver in kernel config:
Device drivers ->Network Device Support -> Ralink driver support -> Ralink rt2800(usb) support
It builds correctly and the USB is detected in the im233, so I see the wlan0 interface with iwconfig. The problem comes up when I try to set the link:
iwconfig wlan0 up
and i get:
rt2800usb 1-1.1:1.0: firmware: requesting rt2870.bin
rt2870.bin is not found, but I think that it is not being built. Do you know what's happening?
