Following the steps in How to Creat A Bootable SDcard http://www.gumstix.org/create-a-bootable-microsd-card.html,
I got my own SD card.But it doesn't work!
The problem may be
u-boot.bin: the boot loader uImage: the Linux kernel I don't know specially "uImage "files stand for ,and use "uImage-2.6.21-r1-gumstix-custom-verdex.bin" .Does it correct? why it fails to work?
