iMX6Q board restart again and again

[hongxingyu1982]

Hi guys

I use mfgtools download boot.img, recovery.img, system.img, u-boot-6q.bin, userdata.img to my target iMX6Q board. After downloading successfully, I am trying to boot the iMX6Q board, but it will not finish boot. It stops displaying to the console after "Freeing init memory:252K", and then restart, and so forth.

But if I download the others four image except userdata.img, it will boot ok.

Attachment is the log, could you help me to solve this issue ?

Thank you very much!

Best regards

Hongxing

which BSP are you using?

please check the partition, size are created properly and your images not exceed the size of the partition.

You can try to create the partition and 'dd' the images to each partition manually.

HI jimmy

Nice to meet you !  Thank you for your reply.

Yes, it seems the partition error.

Now I used iMX6Q as target board. I use 8G eMMC, and have tried "BOARD_USERDATAIMAGE_PARTITION_SIZE := 6189744128#5.9G", and used the mfgtools to download the userdata.img to my target board, but it can't boot. I had changed "BOARD_USERDATAIMAGE_PARTITION_SIZE := 6189744128#5.0G", 4.5G, 4.0G, 3.5G, 3.0G, 2.5G, 2.0G, all of them can't boot.
As I changed the ""BOARD_USERDATAIMAGE_PARTITION_SIZE := 1189744128#1.1G, it is OK.

Could you give me some clues?

By the way, I set BOARD_SYSTEMIMAGE_PARTITION_SIZE := 534773760.

Thanks

which BSP and which MFGtool are you using?

[hongxingyu1982]

Hi Jimmy,

Our project is based on i.MX6 Quad with imx6_android_kk4.4.2_1.0.0-ga_core_source_bsp, and the MFGtool is Mfgtools-Rel-13.01.00_ER_MX6Q_UPDATER\MfgTool2.

Thanks

Different BSP has different MFGtool.

Please use this

i.MX6Q|i.MX 6Quad Processors|Quad Core|NXP    

i.MX 6Family Manufacturing Toolkit for kk4.4.2_1.0.0 (REV KK4.4.2_1.0.0) i.MX 6Family Manufacturing Toolkit for kk4.4.2_1.0.0.  GZ (194.5 MB) IMX_6_MFG_kk4.4.2_1.0.0_TOOL

Hello jimmy

Thank you very much!

I had download the tools, and unzip it. it is Mfgtools-Rel-13.01.00_ER_MX6Q_UPDATER\MfgTool2.exe. But It seems the same as I used before.

So is it the root cause ?

[jimmychan]

So, have you modify the mksdcard-android.sh to match your partition size?

[hongxingyu1982]

Hi JImmy

The partition size of mksdcard-android.sh is as blew:

#!/bin/bash

# partition size in MB
BOOTLOAD_RESERVE=8
BOOT_ROM_SIZE=8
SYSTEM_ROM_SIZE=512
CACHE_SIZE=512
RECOVERY_ROM_SIZE=8
VENDER_SIZE=8
MISC_SIZE=8

So how do I modify it? Could you show me more details.

Thanks

For the partition details, please read the Android User Guide Section 4.4.1 Storage partitions.

Then you can modify the size base on your needs.

Jimmy, the copy and past layout is not very clear, I have capture the screen and upload it. please check.

It seems the same as mksdcard-android.sh.

[jimmychan]

the mfgtool (ucl.xml) execute 'fdisk' with the script 'mksdcard-android.sh' to make the partition on your storage. So you can modify the partition size in the script if needed.

Jimmy, the Android User Guide Section 4.4.1 Storage partitions is shown below:
