Tomorrow, I will repartition my SD card to check once more if it works and in the meanwhile wait for your instructions. I have repartition the card more than once and always the same problem. At the moment I try the debug board to become more information about the kernel panic at the beginning of the boot sequence. Maybe then I have more a clue where to look. I will report if I have more informations. Happy bug finding and fixing. Alex ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: Bad Magic Number while booting from SD card with new uImage!
My Sandisk 8GB breaks also. Some times the partiton and format works and sometimes the card would not be recognized. Always after reboot the whole partion table is away. I also have an 8GByte Sandisk SDHC card and was having exactly the same problems until turning the SD clock on when the Freerunner is suspended. This has been incorporated in the kernels newer than the 4th of September. Since using kernels newer than this i have not had any problems with data corruption on my SD card.

I doubt I find this Amco thing here in UK so I will just buy a few 8MB ones. Just to know, how the SD is formatted? It is a vfat and u-boot use fatload? I am using vfat for uImage and ext3 for rootfs. Currently, rootfs cant be loaded because kernel panics on vfs drivers (or something) but the kernel has started to boot when I renamed it to uImage.bin ;-) I am going to repartition it to see if it will work. Should I go for a smaller rootfs patition instead of 982MB? Maybe 500 or 512MB.
