Android5.1.1-2.1.0-ga: kernel boot issue on SABRESD EVK

[klauswang]

I download android 5.1.1_2.1.0 core images from this link. Then , I use MFG tool(For android5.1.1) to program i.MX6Q image to my imx6q sabresd evk. When I reboot the device, android cannot boot successfully and show the following message.

Android OS for i.MX Applications Processors|NXP

I want to know whether someone also have this issue.

Hi, Weidong, Saurabh & Philippe,

   Thanks.

   I think it maybe a hardware problem in my EVK to casue boot issue. When I port android 5.1.1 to my custom board, it works well.

[weidong_sun]

Hi,

    I burned & tested the version of android BSP  on iMX6Q-SabreSDP board for 2 times, System can normally boot.

Regards,

Weidong

Hi, Weidong,

    I test android4.4.3 and android5.0.0 core image, system can normally boot. But when I use MFG tool program image to emmc or SD card, it cannot boot, and show error message: NULL Pointer.

  The Android in my SABRESD EVK is 4.4.3. Then I use MFG tool to program 5.1.1 image to emmc. Could u help to check whether it has something to do with this?

[saurabh206]

Hi Klauswang

Have you verified your fstab settings is correct for SDCard or eMMC boot?

Thanks

Saurabh

[klauswang]

Hi, Saurabh,

  The Image Package is provided by NXP i.MX android website. And I could see mmcblk3 is use form kernel message(I use emmc boot, and remove SD card for slot 3). So I think the fstab settings is correct.

The version of evk is "MCIMX6Q-SDB version: SCH-27516 Rev B5" .   Could u help me to check whether this EVK (version: SCH-27516) can support android5.1.1?

[ZeeFrench]

This might not be the same since I tested with i.MX7 but if before the crash, you got error messages with "init: cannot find '/system/bin...." the provided system.img is not in the new raw format now required by Android 5.1. If that's your case, you need a linux machine, install simg2img : sudo simg2img system.img system_raw.img.

My 2 cents, Philippe.

[klauswang]

Thanks, Philippe. I have checked i use the right ramdisk. The problem you meet is not the same with me. My problem is that when Android boot , system show "NULL pointer."
