I am trying to build kernel and rootfs for my imx233-maxi board. Basically I am having problems with setting up wifi drivers. I followed the instructions for realtek Wifi usb dongle but that didn't worked perhaps due to a conflict in kernel versions (The prebuild kernel is 2.6.35-6 and the kernel source is 2.6.35-8). So I am compiling kernel using the instructions in the imx233-maxi user guide.
Now I have successfully compiled the kernel and i can see the some images in tmp/deploy/images. Listing shows me the following files.
core-image-minimal-imx233-olinuxino-maxi-20121201105306.linux.sb

Which file should I be copying in the sdcard?
Also in which directory is the built rootfs image?
Root file system is separate from the kernel and its modules.
You can keep the already in use "root file system" with the new kernel and its modules.
