Now I need to bring the board alive over the latest kernel it may be possible to. I've managed to cross-compile 2.26.32 kernel using most of the options I could take from the existing 2.4.24 .config. I could also download the generated uImage to the board using u-boot 1.0.2. Uncompressed OK and then hung. I've checked on mailing lists that the 2.6 series works with dts (device-tree-sources). There are built-in make targets to generate images backward compatibles with ancient u-boot versions. Then I tried one of these targets to build a cuImage.xxx, but trying to boot from it also hangs. I guess there is no make target that correspond to EP852. Could someone point me some directions on what should I probably be missing (from the very start of the "default porting procedure") ? --0015174bec1c794bc3047ad6ac45 Content-Type: text/html; charset=ISO-8859-1 I work on a EP825 (MPC852T) based system running a 2.4.24 linux kernel (which I didn't bring up in first place).
