Hi all! I was following instructions from http://eewiki.net/display/linuxonarm/iMX233-OLinuXino in order to get mainline kernel to boot off of my olinuxino micro board.
I have created two partitions on my SD card: Device Boot Start End Blocks Id System /dev/sde1 2048 67583 32768 53 OnTrack DM6 Aux3 /dev/sde2 67584 7829503 3880960 83 Linux and installed everything as per instructions. However on boot this is what I get on console: HTLLCLC U-Boot 2013.10-dirty (Jan 05 2014 - 19:38:28) CPU: Freescale i.MX23 rev1.4 at 454 MHz BOOT: SSP SD/MMC #0 DRAM: 64 MiB MMC: MXS MMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: Net Initialization Skipped No ethernet found. Hit any key to stop autoboot: 0 mmc0 is current device SD/MMC found on device 0 221 bytes read in 149 ms (1000 Bytes/s) Importing environment from mmc (uEnv.txt)... Checking if uenvcmd is set ... Running default loadzimage ... MMC0: Data error with command 18 (status 0xf0302020)! ** ext4fs_devread read error - block => I couldn't find anywhere what "ext4fs_devread read error - block" means. Found message origin in ext4fs_devread() function in u-boot source after some time but I really can't get my head around on what it means just by reading code. I suspect it doesn't like block sizes or something, not sure. So I changed second partition to ext2 (instead of ext4) an changed env parameters to instruct uboot that it is ext2 partition, nothing changed. Then I changed source header file include/configs/mx23_olinuxino.h and removed #define CONFIG_CMD_EXT4 from it hoping it will remove ext4 support. I also changed hardcoded env parameters in same file from mmcrootfstype=ext4 to mmcrootfstype=ext2. Recompiled u-boot, dd it to sd card, rinse and repeat, got exactly the same response on console you see above. I give up for today after 3 hours of battling with it. I plan to make 3 partitions: amtrak, vfat (for kernel) and ext4 (for rootfs). But if ext4fs_devread persists to complain (and I apparently haven't removed it from code) I don't think it would work either. What is going on? Can anyone give me some pointers what to do next? Thanks, Nidal. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
