Hi,
I have been studying on arm based qq2440.
In the sbc's cd, there are linux kernel-2.6.13 and arm-linux-gcc-2.95.3 toolchain. And also other toolchains,but i want to use this one.

In fact, there are ready images for downloading, but unfortunately they have missing qualifications, namely some of them doesn't recognize usb hardwares and some of them doesn't recognize touch screen and the language of them is Chinese.

So I have to build a new image.

I have tried to build according to the following the steps below:
-tar linux kernel
-commit the arch and cross-compile settings for arm
-make mrproper
-make menuconfig
and set the attributes for my sbc according to the pdf in cd
-make

Yes, the image has been built.But unfortunately, the system has still unrecognized the usb.

Why?

Thanks.

If you get any diagnostic messages, check them carefully. See if there's general problem with the USB subsystem or there's a problem simply with one single driver. I hope that's the second option. In that case you need to review make menuconfig and check carefully if the right usb drivers are choosen and that they do compile and make their way to the image.
