EVM335X Linux NAND boot freezes at "Freeing init memory: 248K"

Other Parts Discussed in Thread: TPS65910, DA8XX, TMP275

Hi, I've tried flashing the am335x-evm on-board NAND chip and tried to boot the AM335X EVM it but fails ding the process (log file pasted in below).

- I installed Ubuntu 12.04 and SDK-5.06. Made a clean build to get all files - MLO, u-boot.img, uImage and ubi.img (with installation example version of base tisdk root fs).  the ubi.img is created with mkfs.ubifs and ubinize utilities.

- I then booted the board from SD card and enter U-boot mode. Use U-boot 'nand write' to flash the files in the following order: MLO, u-boot.img, uImage and ubi.img.  All writes are OK.  Version: U-Boot SPL 2012.10

- I ran nandboot and the NAND boot did load the kernel from the NAND flash and started the kernel, however, it stopped after freeing some init memory and not giving me the expected login.

 I attached the uart log to this message. Any assistance or insight as to  why the boot process stalls would be greatly appreciated.

Also, I powered off the board and removed the SD card. Set SW 3 to NAND boot i.e. switch 2 and 5 are set to ON. Then power on the board, uart channel only writes one line and then stopped:

U-Boot SPL 2012.10 (Jan 22 2013 - 13:38:40)  

 Any help to find out what I did wrong, or, some steps I am missing?

Maybe to  take a step back, it would be helpful to have known working images of MLO, u-boot.img, uImage and ubi.img for the am335x-evm board to test with?  is this something that can be supplied?

Best Regards,

John

    I don't know the reason for your boot failure, but on your question concerning availability of pre-built images - they are available.  Look at your SDK installation and you will find pre-built images for MLO, U-Boot and uImage in folder \board-support\prebuilt-images.

    Regards.

    Thanks for the pointer to the pre built images.  I will give those a try.  Here's some further information on whats been done/tried so far:

    Right out of the ti am335x evm shipping box, I followed the Linux SDK 05.06 guide and,


    - downloaded and created VM Ubuntu 12.04 Linux host on my Windows XP computer

     

    - downloaded and installed ti-sdk-am335x-evm-05.06.00.00 into Ubuntu 12.04

     

    - run setup script OK

     

    - installed MTD-UTILS v1.5 to Linux host

     

    - untared the arago-base-tisdk-image-am335x-evm.tar.gz

     

    - run create SD card script to create a bootable SD with the freshly untared base target filesystem

     

    - on the bootable SD, 'boot' folder contains MLO, u-boot.img and uImage files copied from the 'boot' folder of the base target filesystem.

     

    - the bootable SD's 'rootfs' folder contains the base target filesystem.

     

    - use mkfs.ubifs -r [base targetfs dir] -F -o ubifs.img -m 2048 -e 126976 -c 1580 and then

     

    - use ubinize -o ubi.img -m 2048 -p 128KiB -s 512 -O ubinize.cfg to create an ubi.img

     

    - my ubinize.cfg has:
    [ubifs]
    mode=ubi
    image=ubifs.img
    vol_id=0
    vol_size=192MiB
    vol_type=dynamic
    vol_name=rootfs
    vol_flags=autoresize

     

    - copy the ubi.img to bootable SD card's 'boot' directory.

     

    - booted the evm board successfully with the SD card.

     

    - re-boot the board with the SD card and enter U-boot mode.

     

    - flashed MLO, u-boot.img, uImage, and ubi.img all successfully to the NAND flash on the evm board

     

    - at U-boot, type 'run nandboot' (or 'nand_boot', depending on which version of U-boot is using: 2011.09 or 2012.10)

     

    - nand read is OK and Linux kernel runs OK until it reached the following line then it hang there.

    As a further update.  I tried the pre built images.  Same result.  System hangs after Freeing init memory.  What's confusing is the images work fine from SD card.  Images are successfully programmed into the nand flash. Kernel boots but appears to never get past the init process.

    Your issue is being investigated.  Expect some additional feedback early next week.

    Regards.

    There has been some signficant progress made on this issue...below is an update:

    What I figured out is that I made some changes to a couple 'Makefile'  and did a clean build of Linux kernel. With the new kernel (EABI is still on) image and a new ubi.img created from base rootfs tar file, I flashed them all to the NAND.

    Then start with SD boot to u-boot mode, remove the SD card from the slot and I can run 'nandboot' to boot the kernel and roofs! It no longer hangs at 'free memory'.  I think this indicates that NAND boot is ready to go on my board.

    However, I then tried to power off the board, set SW3 switches to 'NAND' boot mode i.e., Switch 2 and 5 are on. Power the board on and it now hangs with only one line displayed:

    'U-Boot 2012.10 (Jan 30 2013 - 19:03:52)'

     I've pasted in my environment settings below.  Any idea why it might be hangin here?

    Can you clarify what is flashed to SD card and what to nand?  From your discription it sounds like only Linux image and FS are in nand.

    Hi, jschipp,

    I'm currently investigating your issue. I'll post an update by tomorrow.

    Meanwhile would you please give an answer to Tommy's question:

    The following is all programmed to NAND flash:

    MLO, u-boot.img, uImage, and ubi.img all programmed successfully to the NAND flash on the evm board

    Hi John,

    I managed to successfully flash MLO, u-boot.img, uImage and ubi.img to NAND and then boot them entirely from NAND by following the steps below.

    I'm using Ubuntu 12.04 with ti-sdk-am335x-evm-05.06.00.00 and MTD-UTILS v1.5.

    # cd ti-sdk-am335x-evm-05.06.00.00/

    1. Create bootable sd card using the pre-built images (MLO, u-boot.img and uImage) located in ti-sdk-am335x-evm-05.06.00.00/board-support/prebuilt-images/ :
    # ./bin/create-sdcard.sh

    2. Remove all contents from rootfs partition on the sd card:
    # sudo rm -rf /media/rootfs/*

    3. Copy and untar the arago-base-tisdk-image-am335x-evm.tar.gz file system to the root partition of the sd card:
    # sudo cp ./filesystem/arago-base-tisdk-image-am335x-evm.tar.gz /media/rootfs/
    # cd /media/rootfs/
    # sudo tar xvf ./arago-base-tisdk-image-am335x-evm.tar.gz
    # cd -

    4. Create a ubinize.cfg file with the following contents:
    [ubifs]
    mode=ubi
    image=ubifs.img
    vol_id=0
    vol_size=192MiB
    vol_type=dynamic
    vol_name=rootfs
    vol_flags=autoresize

    5. Create ubifs.img and ubi.img from the target filesystem located in /media/rootfs/
    # sudo mkfs.ubifs -r /media/rootfs/ -F -o ubifs.img -m 2048 -e 126976 -c 1580
    # ubinize -o ubi.img -m 2048 -p 128KiB -s 512 -O 2048 ubinize.cfg

    6. Copy ubi.img to the /boot partition of the sd card (the pre-built images MLO, u-boot.img and uImage are already there) :
    # cp ubi.img /media/boot/

    7. Shut down the EVM board and be sure that the SW3 switches are set to boot from SD card. Please refer to AM335x_U-Boot_User's_Guide and please note that "ON" is labeled on the wrong side of SW3 boot mode switch (check the picture in the link). You may also want to check Table 26-7. SYSBOOT Configuration Pins from the AM335x TRM - there you can see what would the boot sequence be with the different SW3 configurations. Also please note that the SW3 contains sysboot switches from 0-7 (0 is the leftmost and 7 is the rightmost).
    If these switches are not set correctly, then maybe this might be causing the issues.

    8. Start the EVM board and boot to U-Boot from the SD Card. In U-Boot run the following commands (marked in bold black color in the log below) to write the images from the sd card to NAND:
    (please check the NAND Layout from the AM335x U-Boot User's Guide)

    9. Shut down the EVM board and be sure to set the switches on SW3 correctly to boot from NAND (refer to the links from step 7.)

    10. Remove the SD card and start the EVM board. Here is what the log messages look like when the board successfully boots entirely from NAND:

    Miroslave,

    Thank you for the very detailed instructions and outputs.  I followed your instructions exactly and confirmed NAND booting is now working correctly.  Thank you for all your help.

     

    Best Regards,

    John

    My 2 cents to the  's  artwork:

    If your U-boot includes USB mass storage support (it does, from the PSP05.06), you may flash the NAND within seconds

    - from USB flash drive

    - from uSD card inserted in the USB-attched card adapter.

    First, place to the root directory of your card (uSD or USB stick) the files: MLO, u-boot.img, uImage, ubi.img

    Then copy-paste to the U-boot prompt the following 5 command lines, one by one:


    usb start; fatls usb 0

    mw.b 82000000 ff 2000000; fatload usb 0 82000000 MLO

    cp.b 82000000 82020000 20000; cp.b 82000000 82040000 20000; cp.b 82000000 82060000 20000

    fatload usb 0 82080000 u-boot.img;fatload usb 0 82280000 uImage;fatload usb 0 82780000 ubi.img

    nand erase.chip; nand write.i 82000000 0 2000000

    Hi, I followed the instructions of this post. My filesystem does not charge in VFS. Bellow is showed the log in boot process and my environment variables.
