[hide]Introduction
This article is for specific 2.6.37.y Linux kernel branch serie.
It is interesting read The Linux kernel article previously.
On this 2.6.37.y version, supported IGEP Processor Boards are:
- IGEP COM MODULE / ELECTRON (IGEP0030)
- IGEP v2 (IGEP0020)
The currently supported IGEP Expansion Boards are as follows:
- IGEP PARIS / BERLIN (BASE0010)
Older IGEP devices (Marvell wifi and NO wifi versions) - P/N: IGEP0020-RCxx, IGEP0030-RExx, IGEP0020-RF7x and IGEP0030-RG7x
Binaries: latest stable kernel version for older IGEP devices is: 2.6.37-11 (20151008)
Newer IGEP devices (TI Wilink8 wifi versions) - P/N: IGEP0020-RF6x, IGEP0030-RG6x
Binaries: latest stable kernel version for newer IGEP devices is: 2.6.37-11-wilink8 (20151008)
Platform | Kernel source | Compat Wireless source | zImage binary | Modules binaries | |
---|---|---|---|---|---|
IGEP00x0 | 2.6.37-11 (md5sum) | compat-wireless-wilink8-0 (md5sum) | zImage-2.6.37-11-wilink8.bin (md5sum) | modules-2.6.37-11-wilink8 (md5sum) |
Build kernel from sources
Download the latest stable version sources (same version/branch for all newer and older igep00x0 devices) and follow next steps:
wget http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-11/linux-omap-2.6.37-11.tar.gz tar xzf linux-omap-2.6.37-11.tar.gz cd [kernel version]
Configure Linux kernel for IGEP devices. IGEP is ARM architecture based device. For newer wilink8 wifi version, it should be used a new 'igep00x0_wilink8_defconfig' file. (patch)
make ARCH=arm igep00x0_wilink8_defconfig
Then build the kernel and kernel modules. The result will be an zImage file in arch/arm/boot directory. Execute:
make ARCH=arm CROSS_COMPILE=[your cross compiler] zImage modules
For example, if you are using IGEP SDK Toolchain (How to setup a cross compiler) then you should execute following cmdline:
make ARCH=arm CROSS_COMPILE=arm-poky-linux-gnueabi- zImage modules
You can install the kernel modules to your target rootfs
make ARCH=arm CROSS_COMPILE=[your cross compiler] INSTALL_MOD_PATH=[path to your target rootfs] modules_install
Download the Compat-Wireless version sources and follow next steps:
wget http://downloads.isee.biz/pub/releases/linux_kernel/v2.6.37-11/compat-wireless-wilink8-0.tar.gz tar xzf compat-wireless-wilink8-0.tar.gz cd compat-wireless-wilink8-0
Load (modify if it is needed) the environment file (setup-env-wl18xx-rmd):
source setup-env-wl18xx-rmd
Compile the Compat-Wireless modules:
cd compat-wireless-wilink8 make KLIB_BUILD=${KLIB_BUILD} modules
Install the compat-wireless modules to your target rootfs
make KLIB_BUILD=${KLIB_BUILD} KLIB=${ROOTFS} install-modules
