== Summary ==
This tutorial will take you through the basic steps to get the 2.6.31 Kernel (LF-Linux-2503-20110602-1237.tar.gz) loading on your Didj. This will only deal with the kernel, and will be set up to run completely from SD, rootfs included.

== Hardware needed ==
[[LeapFrog_Pollux_Platform:_Console_Access| Console Access]]

== Kernel Configuration ==
Here we will configure the kernel for compiling, currently if you are using Lightning Boot 1.4 to 2.1 there is a problem with the bootloaders framebuffer and where the kernel is loaded. Two ways currently around this, create a kernel < 2mb or boot it manually with uboot and a lower address. This tutorial uses the < 2mb method, which is easy to achieve after all the modules for things Didj doesn't have are removed.

After getting your build environment set up, we'll load a default config file:
make lf1000_ts_defconfig

Next edit .config, you can do this with a text editor, or make menuconfig, this is all one line:
CONFIG_CMDLINE="mem=14M mlc_fb=0x00E00000,0x01200000 root=179:02 rw rootfstype=ext3 rootdelay=1 debug=1
init=/sbin/init console=ttyS0,115200 ubi.mtd=Brio ubi.mtd=prg_Brio ubi.mtd=Cartridge ubi.mtd=EXT ubi.mtd=prg_EXT"
ubi.mtd=prg_Brio ubi.mtd=Cartridge"

You will also need to disable a few things, such as Touch Screen, Acellerometer, Camera, USB Host, etc. You can check the example config file for all the options.

Next we need to change the Mach Type in '' /linux-2.6/arch/arm/tools/mach-types '' the number has changed to 2028 - but the boot loader only knows about 1235:

#zir2412 MACH_ZIR2412 ZIR2412 1235
didj MACH_DIDJ DIDJ 1235
...
...

#didj MACH_DIDJ DIDJ 2028

Also edit arch\arm\mach-lf1000\include\mach\mlc.h
#define MLC_MAJOR 251
#define MLC_LAYER_MAJOR 250
This will enable the mlc driver to work with /dev/mlc

Then just run the install script
./install.sh

zImage will be found in the path defined with $TFTP_PATH in your Environmental Variables

Two ways currently around this, create a kernel < 2mb or boot it manually with uboot and a lower address. This tutorial uses the < 2mb method, which is easy to achieve after all the modules for things Didj doesn't have are removed and we've set a couple of things up like tux boot image.
-After getting your build environment set up, we'll load a default config file:
+Unpack your sources to a suitable dir, download the mes_sdhc.c explorer/didj updated mmc driver from the link in the software needed section, copy it to linux-2.6/drivers/mmc/host overwriting the original version.  This enables the sd0 port to be enabled at boot time for the didj and explorer.
-  make lf1000_ts_defconfig
-You will also need to disable a few things, such as Touch Screen, Acellerometer, Camera, USB Host, etc. You can check the example config file for all the options.
+Now download the lf1000.c JFFS2/Partions Enabled file from the software needed section, copy it to linux-2.6/drivers/mtd/nand/, this will allow us to see and mount the didj partitions once we've got the kernel booted.
