Linux/TMDSCSK388: Problems with creating SD card for DM388 camera kit

Part Number: TMDSCSK388

Tool/software: Linux

Hello,

I have modified some configuration options and have compiled using 'make syscal all'. I am trying to write to the SD card as per the steps explained in http://processors.wiki.ti.com/index.php/IPNC_RDK_DM38x_,_DM8127#Boot_setup_for_custom_build.

Here is the script file as provided in the IPNC rdk software. ( I have not modified this script)

#!/bin/bash

        exit
fi

echo "All data on "$1" now will be destroyed! Continue? [y/n]"

if ! [ $ans == 'y' ]
then
        exit
fi

echo "[Partitioning $1...]"

DRIVE=$1

for i in `ls -1 $DRIVE?`; do
 echo "unmounting device '$i'"
 umount $i 2>/dev/null
done

dd if=/dev/zero of=$DRIVE bs=1024 count=1024

echo CYLINDERS - $CYLINDERS
{
echo ,9,0x0C,*
echo 10,,,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE

echo "[Making filesystems...]"

umount "$1"1

mount "$1"2 /mnt
tar zxvf $6 -C /mnt &> /dev/null
chmod 755 /mnt
umount "$1"2

echo "[Done]"
                     

In the script in Line 9:

for i in `ls -1 $DRIVE?`; do

 Is the  '?' required. I tried removing the '?' and I still have the same issue.

For some reason sdb1 and sdb2 are not created. However 'lsblk' shows '/dev/sdb'

Does anyone have a hand on this issue?

  • May I know which Ubuntu Version You are using to run the script ?

  • In reply to Bonthu Loka Nagendra:

    I am using Ubuntu 18.04 LTS with kernel (4.15.0-20-generic). I am running Ubuntu on VMWare.
  • In reply to DM learner:

    Just try to run the sfdisk command present in the script ( 26 line ) then you will come to why that script is not working
  • In reply to Bonthu Loka Nagendra:

    Thanks, Mr. Bonthu. A little reading into this and I see that since version 2.26 for sfdisk, the DOS(-D) and HEADS (-H) options are not supported.
    But how do I solve this? Is using an older version of Ubuntu the only solution?
  • In reply to DM learner:

    There are two solutions for that
    1.do sd-card partition manually and copy boot Image and root file system manually from the path they provided in the guide
    2.Downgrade the sfdisk version, it is under util-linux package and run the script with arguments
  • In reply to Bonthu Loka Nagendra:

    Super!! I will try this.

    Are you also working on DM388 applications. I have just begun working on this platform and would like to discuss and learn different solutions that can be implemented on this platform. Is there any other way of contacting you via email or blog?
  • In reply to DM learner:

    Instead of sfdisk we can add the following 4 instructions in your script and run it

    parted -s $DRIVE mklabel msdos
    parted -s $DRIVE unit cyl mkpart primary fat32 -- 0 9
    parted -s $DRIVE set 1 boot on
    parted -s $DRIVE unit cyl mkpart primary ext2 -- 9 -2
  • In reply to Bonthu Loka Nagendra:

    which part of the script should be replaced for this? should I remove sfdisk and replace it with these 4 lines?

    echo CYLINDERS - $CYLINDERS
    {
    echo ,9,0x0C,*
    echo 10,,,-
    } | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE
    

  • In reply to DM learner:

    Don't remove Just comment it and add those 4 instructions instead of that

    WIth the changes, I am able to create the SD card. However, when running the demo application,I am unable to see any video streaming using the web browser provided by TI. The same is the case using VLC media player. The application is highly unreliable and inconsistent . For the same configuration and setting, it works at times and it does not most of the times.

    Coming back to debugging the issue, after using your suggestions to create the SD card, I see the following  error messages:

    [   31.802341] autorun-usecase.sh[113]: umount: can't unmount /mnt/mmc: Invalid argument
    [   32.282362] autorun-usecase.sh[113]: mount: /dev/mmcblk0 is already mounted or /mnt/mmc busy
    [   32.367414] FAT-fs (mmcblk0p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
    [   32.826313] autorun-usecase.sh[113]: killall: dhcpcd: no process killed
    [   47.596835] autorun-usecase.sh[113]: TimeOut occure in boot_proc.
    [   47.600534] autorun-usecase.sh[113]: Program exit.
    [   51.705604] autorun-usecase.sh[113]: TimeOut occure in boot_proc.
    [   51.706623] autorun-usecase.sh[113]: Program exit.

    As suggested by some of the threads in the forum to resolve the 'time out in boot proc' error, i have done the following, though it did not help:

    1. delete sysenv file from '/mnt/nand/'

    2. Enable full feature option:  IPNC_CONFIG := FULL_FEATURE

    3.  Modified the option : DM388_MCTNF_ON := NO

    However, with all these changes as well, the application does not run consistently. 

    Do you have any ideas on this? 

    I hope TI takes notice of this and replies with a solution.
