Re: [Gumstix-users] Booting from MMC (Micro SD) using OE builds

[arm_555 <ar...@pe...>]

Hi, 

    I follow this page on how to boot a Verdex from microsd
(http://www.gumstix.net/User-How-To-s/view/User-How-To-s/Booting-from-microSD/SD/MMC/110.html)
I'm trying to download kernel from
www.sakoman.net/oe/mmc-boot/kernel-mmc.tar.gz and rootfs from
www.sakoman.net/oe/mmc-boot/rootfs-mmc.tar.gz but the link seem to be
broken. Anyone know where I can download the kernel and rootfs files from? 

Thank you, 

     Arm
