BIIIIIIIIIIIIIIIG THANKS to Adrynalyne over at PPCGEEKS for compiling this guide! Sorry I forgot to post my gratitude where it is due.
Part 1
Installing GNU/Linux
Not sure why my first post was deleted as it does pertain to the Droid, But its all good.
First, you will need GNU/Linux. Use any distro you like, but for ease, Ubuntu will work fine. Unless you plan on making a dual boot or using it as a main OS, wubi will be one of the easiest ways. It will install Ubuntu onto your Windows partition in a folder of its own. Uninstall is easy as well, you can do it from the control panel. You can also do this under a VM, but wubi is going to be easiest to set up.
Getting Ubuntu

Then, burn the iso to a CD. To install with Wubi, simply start the setup on the CD from within windows. Follow the directions and you are on your way to installing Ubuntu. When you reboot you will be presented with the choice to boot Windows, or Ubuntu.
Part 2
Setting up Git and kernel source
Getting the kernel source will be done by using this code below. You can literally copy and paste it from here into the ubuntu terminal.
Code:
mkdir -p ~/kernel/droid
cd ~/kernel/droid
git clone git://android.git.kernel.org/kernel/omap.git
git clone git://android.git.kernel.org/platform/system/wlan/ti.git
git clone git://android.git.kernel.org/platform/prebuilt.git
This does take a bit.
The next part is to set git to the version of kernel we want to use. In this case, we will want the latest Eclair source, as its the only kernel that works on ESE53+.
Code:
cd ~/kernel/droid/omap
git checkout --track -b android-omap-2.6.29-eclair origin/android-omap-2.6.29-eclair
cd ~/kernel/droid/ti
git checkout --track -b eclair origin/eclair
cd ~/kernel/droid/prebuilt
git checkout --track -b eclair origin/eclair
Part 3
Configuring kernel options (like tethering and overclocking)
First, lets setup the build environment.
Code:
cd ~/kernel/droid/omap
export ARCH=arm
export CROSS_COMPILE=~/kernel/droid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
make sholes_defconfig
Kernel configuration happens a few ways. You can use menuconfig (gotta install ncurses dev tools)
Code:
cd ~/kernel/droid/omap
make menuconfig
or the more advanced method of modifying the .config file.
The .config file is a hidden file in the ~/kernel/droid/omap. I wil attach mine. Here is where much of the kernel config takes place.
Other more advanced things, such as overclocking, take place in the ~/kernel/droid/omap/arch//arm/mach-omap 2 directory.
To overclock, check out the board.sholes.c file, specifically this part:
Code:
static struct omap_opp sholes_mpu_rate_table[] = {
{0, 0, 0},
/*OPP1*/
{S125M, VDD1_OPP1, 0x20},
/*OPP2*/
{S250M, VDD1_OPP2, 0x27},
/*OPP3*/
{S500M, VDD1_OPP3, 0x32},
/*OPP4*/
{S550M, VDD1_OPP4, 0x38},
/*OPP5*/
{S600M, VDD1_OPP5, 0x3E},
};
Speeds are shown/set here, as well as voltages. I haven't messed with this too much yet. This is also linked to the file omap3-opp.h, where the speed settings are defined. I believe most must be editted.
Code:
/* MPU speeds */
#define S600M 600000000
#define S550M 550000000
#define S500M 500000000
#define S250M 250000000
#define S125M 125000000
Enabling the 600mhz mode (and the fifth cpu slot?) requires modifcations to the clock34xx.c file. I will upload mine.
To tether, you will need to enable netfilter and iptables stuff in the kernel. Most of this stuff is NOT in .config, but you can add it. It only requires three lines to enable it, but then the questions that come during compilation are annoying, long, and make it easy to make errors. The .config file I loaded has this already, but I will list the sections as well. These get added to .config. Be careful not to duplicate sections.

When you are done configuring your .config file, BACK IT UP. Each time you setup the build environment, it erases it and makes a default copy. Just watch the prompts and when it does that, replace the new .config file with your own.
Part 4
Compiling kernel and wifi driver
Ready for this? While still in the omap directory (~/kernel/droid/omap)
Code:
make
Now watch the initial prompts. Sometimes it once again nukes your .config file. I have no idea why. So just hit ctrl-x and cancel the compile, and then put your .config file back and make it again.
Now for the wifi.
Code:
cd ~/kernel/droid/ti/wilink_6_1/platforms/os/linux
export ARCH=arm
export CROSS_COMPILE=~/kernel/droid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-
export HOST_PLATFORM=zoom2
export KERNEL_DIR=~/kernel/droid/omap
make
The driver will be located under ~/kernel/droid/ti/wilink_6_1/platforms/os/linux.
Put it on your sd card for safe keeping. You need to build this driver, every time you recompile the kernel.
Part 5
Packaging kernel
Make a new directory under your home folder called bin. Log out and back in to get it into your path.
Attached is a zip file of two files you need. Copy mkbootimg into your bin folder, and boot.img-ramdisk.gz into the ~/kernel/droid folder.
To package the kernel into a boot.img file:
Code:
cd ~/kernel/droid
[Only registered and activated users can see links]
File will be located in ~/kernel/droid folder. Copy this to your sd card.
Part 6
Flashing kernel and hosing your phone
You cannot do this from within Android, so reboot to recovery mode.
You will also need adb setup for this. In SPRecovery, go to mount options and mount the sd card.
Code:
adb shell
flash_image boot /sdcard/boot.img
Reboot.
Once back up (assuming you booted), install the wifi driver.
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
busybox cp /sdcard/tiwlan.ko /system/lib/modules/tiwlan.ko
sync
reboot
Thats the main meat of it. Many things can be added and modified that go beyond this tutorial. The sky is the limit.
