Contents
Downloads
- PlatformX 1.0 Release from sourceforge.net
- MSB2 Patches from msp/system/kernel available here
- iMote2 Toolchain (either the normal handheld.org toolchain or perferably the Mainstone version with an updated version of binutils
- the 2.6.14 linux kernel available from kernel.org
Steps
Extracting all the Images
-
Assuming you placed the platformX release, patches, and kernel in the same directory you could extract them all using the following commands:
<bash>tar zxf linux-2.6.14.tar.gz
tar zxf SG2Release-1_0.tgz
tar zxf msb2_patches.tgz</bash>
Patch the kernel
-
First we apply the SG2 release patches then we apply our MSB2 patches:
<bash>cd linux-2.6.14
echo "Applying SG2 Patches"
patch -p1 < ../SG2Release-1_0/src/patch-2.6.14-sg2-10
echo "Applying MSB2 Patches"
patch -p1 < ../msp-linux-2.6.14-pxa-mmc.patch
patch -p1 < ../msp-linux-2.6.14-uart.patch
patch -p1 < ../msp-linux-2.6.14-sd-detect.patch</bash>
Configure the kernel
-
At this point you can either use the normal SG2 configuration or apply the msb2 standard configuration. Be sure to add your toolchain to your path, if you've installed it in /usr/local/arm/3.4.3_binutils you could do something like this:
<bash>export PATH=/usr/local/arm/3.4.3_binutils/bin/:$PATH
export ARCH=arm
export CROSS_COMPILE=arm-linux-</bash>
- export ARCH=arm
- export CROSS_COMPILE=/usr/local/arm/3.4.1/bin/arm-linux-
- export PATH:=${PATH}:/usr/local/arm/3.4.1/bin/
SG2 Configuration
-
<bash>export ARCH=arm
export CROSS_COMPILE=arm-linux-
make stargate2_defconfig
make oldconfig</bash>
MSB2 Configuration
-
<bash>export ARCH=arm
export CROSS_COMPILE=arm-linux-
cp ../msp-linux-2.6.14-config ./.config
make oldconfig</bash>
RNDIS (Windows XP) Ethernet Gadget Configuration
-
If you'd like to be able to connect the iMote2 to a Windows XP host instead of a linux host you can use the RNDIS patch to add Windows XP support to the kernel. Download the patch from here to your build directory. Note, that this patch currently compiles support into the kernel and not as a module.
<bash>export ARCH=arm
export CROSS_COMPILE=arm-linux-
cp ../msp-linux-2.6.14-config ./.config
patch -p1 < ../msp-linux-2.6.14-winXP-rndis.patch
make oldconfig</bash>
Compile the kernel
You can then build the kernel as you normally would or perform any additional steps you want to before building. Note that if you are using the Mainstone tools instead of a 3.4.1 toolchain installed in /usr/local/arm/3.4.1 you will need to edit Makefile.platx and comment out the export lines at the top. <bash>...
... </bash>
<bash>mkdir ../kernel make zImage make modules make modules_install cp -a arch/arm/boot/zImage ../kernel/ cp -a modules/lib/modules/2.6.14_r1.0/ ../kernel/ </bash>
