# This Doc explains how to boot Android on phyFLEX-i.MX6 RDK.
This is tested with SD-Card.

1) Take a 4 GB SD-Card.
2) Partition it into 3 part as follows.
	a) First partition of FAT filesystem with 200 MB of size. label it as boot
	b) Second partition of EXT4 filesystem with 2 GB of size. label it as rootfs
	c) Third partition of FAT filesystem with remaining size. label it as data
3) Copy the zImage to boot patition.
	Note: We assume that all the other bootable images barebox.img is flashed to SD-card/Nand earlier.

4) Extract the android_rootfs.tar.bz2 file to rootfs partition.

	Note: After extracting the file permissions may change.
		For android smooth boot the following permissions to be set for the files explained below.
		
		sudo chmod 644 /media/rootfs/init.*
		sudo chmod 644 /media/rootfs/ueventd.*
		sudo chmod 644 /media/rootfs/fstab.*

5) Keep the data partition Empty for this release.

6) Now Powerup the board and change the bootargs as follows.
	

console=ttymxc3,115200 androidboot.hardware=freescale androidboot.console=ttymxc3  init=/init vmalloc=256M  video=mxcfb0:ETM0700G0DH6,bpp=32 fbmem=10M,28M video=mxcfb1:hdmi,1280x1024M@60,bpp=32 if=RGB24 vt.global_cursor_default=0 consoleblank=0 board_mx6q_phyflex.csi0=none board_mx6q_phyflex.csi1=none ip=none root=/dev/mmcblk0p2 rootfstype=ext4 noinitrd rootwait mtdparts=n25q128:512k(barebox)ro,128k(bareboxenv),2M(splash),-(kernel);gpmi-nand:512k(barebox)ro,128k(bareboxenv),2M(splash),8M(kernel),-(root)


	To make the bootargs as above edit the variable in env/config file in the barebox as follows
	
	kernel_loc=disk

	rootfs_loc=disk

	rootfs_type=ext4

	kernelimage=zImage

	display=ETM0700G0DH6
	
	bootargs="console=ttymxc3,115200 vmalloc=256M"

	# The below are required for Android boot

	bootargs="$bootargs androidboot.hardware=freescale androidboot.console=ttymxc3 init=/init"

	bootargs="$bootargs video=mxcfb0:$display,bpp=32 fbmem=10M,28M"

	bootargs="$bootargs video=mxcfb1:hdmi,1280x1024M@60,bpp=32 if=RGB24"
