RTOS/OMAP-L138: I got an error when I run a create-sdcard-omapl13x.sh script.

Part Number: OMAP-L138


Tool/software: TI-RTOS

Hi Champs,

Could you please let me know what is to be substituted for sfdisk -D option?
I tried a SD card formatting according to a description below and got an error.

  o TI EP Wiki: Processor SDK RTOS BOOT OMAPL13x
    (processors.wiki.ti.com/.../Processor_SDK_RTOS_BOOT_OMAPL13x)

    - MMCSD Boot Mode

      - Formatting the SD Card

        sudo sh create-sdcard-omapl13x.sh <Drive Name>

The error messages was as below.

  $ sudo sh create-sdcard-omapl13x.sh /dev/sda
  [sudo] password for user:
  create-sdcard-omapl13x.sh: 4: create-sdcard-omapl13x.sh: [[: not found
  Un mounting all the partitions...
  umount: /: target is busy
          (In some cases useful info about processes that
           use the device is found by lsof(8) or fuser(1).)
  1024+0 records in

  DISK SIZE - 274877906944 bytes
  sfdisk: invalid option -- 'D'

I found that the sfdisk command version is v2.27.1 and it dose not provide the -D option as followings

  $ sfdisk -v
  sfdisk from util-linux 2.27.1

  $ man sfdisk

  NOTES
         Since  version  2.26  sfdisk  does  not  provide  the   --DOS,   --IBM,
         --DOS-extended, --unhide, --show-extended, --cylinders, --heads, --sec‐
         tors, --inside-outer, --not-inside-outer options.

I'm not sure how to avoid the error.

Regards,
j-breeze

    Hi,

    I am sure you did this, but can you double-check that /dev/sda is your sd card?? Usually this is the hdd.

    Also prior to executing the create-sdcard.sh can you try to delete its partitions & format it? Also try doing umount /dev/sdb before executing the script.

    Best Regards,

    I think you only have couple options.
    1) Edit the script file. Remove the "-D" from the sfdisk call. The "-D" seems to be for reserving space for a DOS MBR. I don't know enough about MBRs to figure out if there is an equivalent options on the new sfdisk. Try without the "-D" option and see if it works.
    2) Roll back sfdisk to 2.26.

    Hi Yordan,

    Thank you for your advice.

    I could recognize my sd card as /dev/sdb as below.

    Hi Norman,

    All options of sfdisk used in the script are not provided already. So, could you please let me know how to roll back sfdisk to 2.25?

    Not sure what you mean bye "not provided already". I suggest modify create-sdcard-omapl13x.sh line from
    sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE << EOF
    to
    sfdisk -H 255 -S 63 -C $CYLINDERS $DRIVE << EOF
    Run the script again. Test the SD Card. It might not matter if the "-D" is missing.

    Rolling back sfdisk depends on your linux host. I haven't worked with linux in a long time. I remember you have to look up how to use the package installer/uninstaller. You should be able to uninstall sfdisk and reinstall an older version.

    Hi,

    I modified the script as you told me and got an error below.

      sfdisk: invalid option -- 'H'

    -H is same as --heads. -S is same as --sectors. -C is same as --cylinders. So, what I wanted to say is that the sfdisk v2.27.1 dose not provide the -D / -H / -S / -C options

      $ man sfdisk

        NOTES
               Since  version  2.26  sfdisk  does  not  provide  the   --DOS,   --IBM,
               --DOS-extended, --unhide, --show-extended, --cylinders, --heads, --sec‐
               tors, --inside-outer, --not-inside-outer options.

    Hi Norman, Hi Yordan,

    I got the v2.25.2 util-linux package file (util-linux_2.25.2-6_amd64.deb) and installed it. Then I could run the script.
    Thank you for your support.

    However, I really hope that "Formatting the SD card from Windows PC" will be supported in the next release.

    Ah...I understand now. After reading up on sfdisk, the linux guys seem determined to remove any DOS concepts of C/H/S from all the partition utilities. Reducing the sfdisk command down to
    sfdisk $DRIVE << EOF
    might work. The values for C/H/S that sfdisk thinks it should use might be okay with the OMAP bootloader.

    A search of E2E forum would indicated that this is a recurring problem. TI does not seem aware of the problem with all their SD card scripts. The TI Wiki does not even note sfdisk version requirements.
