Hi all. I have a mini6410 board, and I trying to run Debian from a SD but I can't do it. I'm following this tutorial. http://code.google.com/p/mini2440/wiki/Emdebian Steps I do. - Install OS with deboostrap. - Create a EXT3 partition in the SD - Copy SO to SD - Copy zImage(included in the DVD) to SD (/) - Upload u-boot_sd to the NAND. The problem... I don't know how to tell U-boot how to boot the system from the SD using the zImage of the SD. I had lucky in a test where I used a zImage on the NAND and the file system of the SD. in that test the second stage of debootstrap finish succesfully. I tried to do the same again but always I got a message error mounting the SD on /r. How can I install Debian on a SD and boot from it? żUsign superboot how I can setup the parameters of uboot? In all tutorials(mini2440) always I see the setenv command to config de boot args, but, in superboot how can I do it? I used the option S of superboot to set parameters like: console=ttySAC0,115200 noinitrd root=/dev/mmcblk0p2 rootwait=4 rw init=/bin/sh. That it's the right way? I'm new in embebed systems and it is a little dificult to me. Thanks :) PD: Sorry for my english, I speak spanish.
