video tell kernel/driver which
resolution/depth and refresh
rate should be used or tell
kernel/driver not to register a
framebuffer device for a
display device.
video=mxcfb0:dev=ldb,LDB-
XGA,if=RGB666,bpp=32
or
video=mxcfb1:dev=hdmi,
1920x1080M@60,if=RGB24
,bpp=32
or
video=mxcfb2:off
To specify a display
framebuffer with:
video=mxcfb<0,1,2>:dev=<l
db,hdmi>,<LDB-XGA,xres x
yresM@fps>,if=<RGB666,R
GB24>,bpp=<16,32>
or
To disable a display device’s
framebuffer register with:
video=mxcfb<0,1,2>:off
vmalloc
vmalloc virtual range size for
kernel
vmalloc=256M vmalloc=<size>
androidboot.console The android shell console,
should be same as console=
androidboot.console=ttymxc
0
To use the default shell’s job
control, like Ctrl-C to
terminate a running process,
you need to set this for
kernel.
fec_mac Setup the FEC mac address fec_mac=00:04:9f:00:ea:d3 On some QWKS/EVB board,
the SoC does not have MAC
address fused in, so if you
want to use FEC, please
assign this parameter to
kernel.
cma CMA memory size for
GPU/VPU physical memory
allocation
cma=384M It is 256M by default
androidboot.selinux
Argument to disable selinux
check and enable serial input
when connecting a host
computer to the target
board’s USB UART port.
Please refer below link for

androidboot.selinux=disable
d
As since Android Lollipop 5.1
CTS requirement: serial input
should be disabled by
default. Setting this argument
enables console serial input,
which will violate the CTS
requirement.
Setting this argument will
also bypass all the selinux
rules defined in Android
system.
Recommend to set this
argument for internal
