Troubleshooting Embedded Linux Boot on Beaglebone Black

Hello guys:
I’m running into an issue.
So I’m doing this exercise that teaches one about the booting stages in Embedded linux. Board is Beaglebone black.
Task details:
Booting an image off the SD card.
Things i have done:
1. partitioned my SD card into BOOT(fat16) and ROOTFS(ext3).
2. In BOOT Partition i have copied the MLO file, U-Boot file, and UEvn.txt file into it.
3. In the ROOTFS, I have the necessary linux filesystem in it too. (mnt, proc, boot, etc)

Each time I try booting from the SD card, my boot process hangs:
Here’s the Log:
file0.jpgfile1.jpgfile2.jpg

    Yes it always hangs at [ 0.192668] jffs2: version 2.2. (NAND) (SUMMARY) οΏ½Β© 2001-2006 Red Ha
    Ok, i will try this and give feedback.

    Little reseach was suggesting I should disable initializing the NAND flash access on the uEnv.txt since I’m booting from SD card.

  2. ming_58391#0000

    Given I can see you are reading from the sd card – you can probably save disabling NAND until we have tried other things.

  3. ming_58391#0000

    This is all assuming you are reading from the SD Card – do you get `CCCCCCC` when booting without the SD card?

    I can see from the log that:
    – The BBB is reading u-boot
    – U-boot reads the kernel and the device tree
    – It boots the kernel (which at the 3.8.10 is an impressively old kernel!)

    One of the things I have seen like this is when the loading of the DTB overwrites the end of the kernel. Does it always hang after loading the JFFS with an incomplete line?
    `[ 0.192668] jffs2: version 2.2. (NAND) (SUMMARY) οΏ½Β© 2001-2006 Red Ha`

    In your uEnv.txt try either lowering the Kernel address (e.g. 80000000) or increasing the DTB address (e.g. 89000000)
