Jelly bean 4.2.2 patch - Testing with SD Card

[santoshkadam]

Hi,

I am having a iMX.6 SABRE MCIMX6Q-SDP board. On this board - I am have compiled 4.2.2 source code with the patches from freescale. I would like to test this on my board. When I created the SD Card using the "fsl-sdcard-partition.sh" script. I have made necessary changes to the SW6 switch so that the board boots from SD Card.

Please note that I have applied the patch-- that changes the fstab.freescale and vold.fstab as advised in the Android_User_Guide.PDF . Section3.3.2

When I plugin the card, and try to boot - the boot procedure is stuck at the following lines...

=====

mxc_asrc registered

mmc0: new high speed DDR MMC card at address 0001

mmcblk0: mmc0:0001 SEM08G 7.39 GiB

mmcblk0boot0: mmc0:0001 SEM08G partition 1 2.00 MiB

mmcblk1: mmc1:e624 SU16G 14.8 GiB (ro)

==============

I have attached a complete log with this mail. Can someone share some pointers for investigation?

Regards

Santosh.

1. Which fsl-sdcard-partition.sh did you use? seems to be two, one on the manufacturing tool and the other in the android source code. Please you the one on the android source code.

2. Always add '-f' so after partitioning, images are flashed into the SD.

3. I had the same issue as you, but with the SD DEMO image. Seems that in order to boot the SD demo image, the board should have an Android system on eMMC :smileysad: Know issue and It will be fixed.

Hi,

I have tried using the fsl-sdcard-partition.sh and I think, it still has some issues. I worked out this using the fastboot method of downloading the bootloader, and the images. This has worked for me and I am able to boot the android 4.2.2 latest sources. This issue can be considered as closed.

thanks for your pointers.
