Hi, I have tried the instructions at http://wp.angstrom-distribution.org/?page_id=53 for building two example Yocto-based Angström images but I can't get the resulting files to boot up.
I have used this information to partition a 4GB SD card: https://code.google.com/p/beagleboard/wiki/LinuxBootDiskFormat Recent fdisk versions use LBA-only partitioning by default and because of SSD alignment and GRUB2 space requirements, the minimum sector where the first partition can start is 2048. Fortunately, the "-c=dos -u=cylinder" options can be used to switch back fdisk to DOS-compatible mode. I copied MLO, u-boot.img (renamed to u-boot.bin) and uImage (kernel 3.2.28) to the FAT32 partition in that order, syncing and remounting the partition between copying the files, just to make sure MLO and u-boot.bin are placed correctly first. These are the only lines I get when booting: ----8<----8<----8<----8<----8<----8<----8<----8<----8<---- Texas Instruments X-Loader 1.4.2 (Nov 10 2009 - 13:11:00) Reading boot sector Loading u-boot.bin from mmc ----8<----8<----8<----8<----8<----8<----8<----8<----8<---- I have an older, correctly bootable image and I used the MLO/u-boot.bin files from there on my newly partitioned and reformatted SD card with the new kernel. Now, at least it loads u-boot and the kernel, but the kernel stops. I got these lines in minicom: ----8<----8<----8<----8<----8<----8<----8<----8<----8<---- Texas Instruments X-Loader 1.4.2 (Nov 10 2009 - 13:11:00) Reading boot sector Loading u-boot.bin from mmc U-Boot 2009.03 (Jun 05 2009 - 16:39:37) OMAP3503-GP rev 2, CPU-OPP2 L3-165MHz OMAP3 Beagle board + LPDDR/NAND DRAM: 128 MB NAND: 512 MiB In: serial Out: serial Err: serial Board revision Ax/Bx Die ID #2ef40004000000000403a1f302015023 Hit any key to stop autoboot: 0 OMAP3 beagleboard.org # boot reading MLO 19928 bytes read HW ECC selected NAND read: device 0 offset 0x0, size 0x4dd8 19928 bytes read: OK Total of 19928 bytes were the same MLO NAND OK reading uImage 4335504 bytes read ## Booting kernel from Legacy Image at 80300000 ...

How can I use the newly built MLO/u-boot files? Should I somehow reset the board before I can do that? 2. I tried the kernel with different console=ttySn,... settings, nothing produced kernel messages. I suppose it doesn't boot. 3. The Angström bitbake process doesn't produce plain *.sdcard files like the one for Freescale. Why? Thanks in advance, Zoltán Böszörményi _______________________________________________ Angstrom-distro-users mailing list Angstrom-distro-users@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-users
