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

No gpc device node -9, force to ldo-enable.
Power: using LDO mode!

Uncompressing Linux... done, booting the kernel.
But then, it fails to init the system
