Hi, I am trying to boot from sdcard using u-boot. The kernel used is linux-2.6.29-mini2440-20090708.tgz which came along the cd with my mini2440 board. I compiled and created a uImage. Following tutorial at http://mini2440.spaceopera.org/site/developmentenviroment/stepbystep/ind... I am able to boot linux. But I am unable to mount rootfs. Following the tutorial sdcard is formatted properly as mentioned in tutorial. This I am sure because after loading uImage and the File system uploaded by the author of tutorial everything works fine and I was able to get android up. Then i thought of using the kernel and root_qtopia.tgz which came along with the cd. I want to mention here that I just extract root_qtopia.tgz into ext3 partition in the sdcard. I am doubtful at this stage. I think I am missing something at this point. u-boot expects a jffs2 image.... May be I need to do some more steps to create jffs2 from root_qtopia content. Following is the error I get: U-Boot 1.3.2-mini2440 (Oct 6 2009 - 12:51:09) I2C: ready DRAM: 64 MB Flash: 2 MB NAND: 128 MiB Found Environment offset in OOB..
