booti fails to initialize and run android

[oussama]

I've using android 4.4.2/imx6. I've installed boot.img and system.img in sdX1 and sdX5. I do not using the recovery.img.

I've set the bootargs to  'console=ttymxc0,115200n8 earlyprintk vmalloc=400M  video=mxcfb0:dev=ldb,LDB-AM-800480STMQW-TA1,if=RGB666 ldb=sin0 init=/init androidboot.console=ttymxc0 androidboot.hardware=freescale'

Then I tried to boot with booti mmc0

The kernel boots successfully as you can see here:

U-Boot > booti mmc0

booti mmc0

kernel   @ 10808000 (4047468)

ramdisk  @ 11800000 (499651)

kernel cmdline:

  use boot.img command line:

  console=ttymxc0,115200n8 earlyprintk vmalloc=400M  video=mxcfb0:dev=ldb,LDB-AM-800480STMQW-TA1,if=RGB666 ldb=sin0 init=/init androidboot.console=ttymxc0 androidboot.hardware=freescale

No gpc device node -9, force to ldo-enable.

Power: using LDO mode!

Using machid 0x1308 from environment

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

But then, it fails to init the system

Hi oussama

seems you missed to add kernel parameter "root" (indicates the

location of the root file system). Please check attached

Android_User's_Guide.pdf 5.4.2 Kernel command line from

IMX6_KK442_100_ANDROID_DOCS

also you may wish to try more new android 4.4.3

MX6_KK443_200_ANDROID_SOURCE_BSP
