fsl-sdcard-partition.sh is giving error File partition-table.img not found

[msingh1920]

Hi Sir,

I am using iMX8M Mini and Android AOSP Source code for Android 9.0.

I have downloaded the AOSP and successfully able to built it using steps given in Android user guide Rev. P9.0.0_1.0.0-ga, 01/2019 .

I checked my =>  /out/target/product/evk_8mm/    Directory and I can see all the output files there. 

Now i want to flash these output files in my sdcard and test the build images.

for that i am following the steps given in 5.1.1 Storage partitions of Android user guide Rev. P9.0.0_1.0.0-ga,

As per the steps when i am trying to execute fsl-sdcard-partition.sh file I get error saying =>

File partition-table.img not found. Please check. Exiting

Below Command I am executing =>

sudo ./device/fsl/common/tools/fsl-sdcard-partition.sh -f imx8mm /dev/mmcblk0
imx8mm bootloader offset is: 33
File partition-table.img not found. Please check. Exiting

NOTE : - My sdcard is 16GB and I connected my sdcard to my laptop using sdcard adapter and i can see it as /dev/mmcblk0 .

NOTE - In /out/target/product/evk_8mm/ directory also there is fsl-sdcard-partition.sh script and when i try to execute from there also then also i get similar error.

 sudo ./out/target/product/evk_8mm/fsl-sdcard-partition.sh -f imx8mm /dev/mmcblk0
imx8mm bootloader offset is: 33
File partition-table.img not found. Please check. Exiting

Note : - I checked /device/fsl/common/tools/   directory as well as   /out/target/product/evk_8mm/ directory also and I can see partition-table.img file there along with partition-table-7GB.img and other files.

When I run file command on partition-table.img i get below msg =>

file partition-table.img
partition-table.img: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,1), end-CHS (0x3ff,255,63), startsector 1, 27262975 sectors, extended partition table (last)

there is no symbolic link or anything...

because of this error i am not able to flash build images on my sdcard and got stuck here.

Please help me why i am getting this error and how to solve it.

Thanks & Regards,

Now I am able to use  fsl-sdcard-partition.sh script properly..

But after running the script i am getting below error -

Using gdisk and parted i corrected my sdcard and reformatted it but still i am getting same error.

When i independent run the gdisk command i get this msg =>

sudo gdisk /dev/mmcblk0

Partition table scan:
  MBR: protective

  APM: not present
  GPT: present

Found valid GPT with protective MBR; using GPT.

Command (? for help):

But when i run fsl-sdcard-partition.sh i get same error as posted above...

I reformatted and corrected GPT of my sdcard multiple time but same error i am getting again and again.

NOTE : - I am using 16gb sandisk ultra micro sd card and connecting my sdcard with my laptop using sdcard adapter.

Any Suggestion or Idea how can i solve this issue? or why this issue is coming ?

Thanks & Regards,

Hello,

This could be related to the device node you're using since the script runs using /dev/sdX,

Could you try using an SD reader?

And run the command:

sudo ./fsl-sdcard-partition.sh -f imx8mm -c 14 /dev/sdX

X is the disk index from 'a' to 'z'

-c 14 because you're using a 16GB SD Card

Hope this helps,

Best regards,
Aldo.

Hi Aldo Gutierrez,

Thanks for your reply.

Your suggestion was very helpful and now i am able to flash images into SDCARD. using card reader.

But i have few doubts -

1. In my first comments as i mentioned when i try to run fsl-sdcard-partition.sh it gives error saying -

    "File partition-table.img not found. Please check. Exiting"
    even though the file is present there. 

   I solved it by making all the files in the directory executable and some how it works but i am still now sure what can be

   proper solution to this problem. sometimes it work sometimes not.

2. As you mentioned in your commends - sudo ./fsl-sdcard-partition.sh -f imx8mm -c 14 /dev/sdX

   there is no partition-table-14GB.img files created in my directory...  I copied and renamed the partition-table.img to
   partition-table-14GB.img file. So is it the proper way of creating partition-table-14GB.img file ?? or AOSP itself create this
   file during build ? In Android user guide documents no where it is mentioned about partition-table-14GB.img files.

3.  I am able to flash the images on SDCARD and it is working fine. but by default it flashed images for HDMI support.

     But if i want to flash files which support MIPI-DSI display then how can i do this ? 

    I mean to say -> the fsl-sdcard-partition.sh script by default uses  vbmeta-imx8mm.img and dtbo-imx8mm.img files.

    but if i want to use vbmeta-imx8mm-mipi-panel.img and dtbo-imx8mm-mipi-panel.img files which is needed for
    MIPI-DSI display support then how can i do that using this fsl-sdcard-partition.sh script ?

    Thanks & Regards,

    Maneesh

Hi Maneesh,

1.- I have tried on my side and works properly, please try changing the owner of the file to nobody.

2.- No, sorry that was my mistake, I took the i.MX6 as an example and forgot about the default for the i.MX 8MM is 16GB, so don't worry about it, and sorry for the confusion.

3.- the Easy way should be renaming the files, i.e.

vbmeta-imx8mm.img > vbmeta-imx8mm1.img  (to avoid deleting the file)

vbmeta-imx8mm-mipi-panel.img > vbmeta-imx8mm.img

Hope it helps,

Regards,

Aldo.
