I'm using an imx6dl board with 1GB Ram and Android BSP

After running and updating register values after ddr calibration I flashed the new images but the board goes into panic and reboots.

 

this is the kernel command line

 

BOARD_KERNEL_CMDLINE := console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,fbpix=RGB32,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=448M galcore.contiguousSize=33554432 buildvariant=userdebug androidboot.selinux=permissive androidboot.dm_verity=disabled

 

when I change it to

 

BOARD_KERNEL_CMDLINE := console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,fbpix=RGB32,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=128M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=448M galcore.contiguousSize=33554432

 

the board boots but continuous prints are seen on the console.

 

is there anything else I need to change?
