Overview
The Linux kernel for the CompuLab CM-FX6 System-on-Module / Computer-on-Module provides support for on-board peripherals and abstracts the functionality provided by the hardware. Current support coverage is specified at O/S support coverage map page. CompuLab provides ready-to-run binary kernel images, and source code of the modifications and additions made to the Linux kernel to work properly with CM-FX6 modules.
Kernel command line
The Linux kernel for CM-FX6 is shipped with built-in command line parameters:
console=ttymxc3,115200 root=/dev/mmcblk0p1 rootwait
The default kernel command line defines primary console and root device.
Setting U-Boot bootargs environment variable overrides default kernel command line and can be used to set desired kernel parameters.
Building kernel for CM-FX6
Cross-Compiler
There are several options for cross-compilation toolchain setup. You can either compile your cross-compiler or use an already built cross-compiler. The cross-compiler should support the ARM embedded-application binary interface ("EABI")
- Pre-built toolchain:
- Tools for creating cross-compilers:
- Crosstool-ng: Builds a cross-compiler from source. Non-distribution specific.
- Crossdev: Gentoo's cross-compiler builder. Needs Gentoo.
U-Boot mkimage tool
U-Boot mkimage utility is required in order to create kernel images that can be loaded by the CM-FX6 bootloader. You can download prebuilt mkimage binary or build it yourself:
mkdir ~/tmp
cd tmp
wget ftp://ftp.denx.de/pub/u-boot/u-boot-latest.tar.bz2
tar -xjvf u-boot-latest.tar.bz2
cd u-boot-20xx.xx
touch include/config.{h,mk}
make tools
sudo install tools/mkimage /usr/local/bin
Getting kernel sources
There are two ways to get Linux kernel sources that can be used as a baseline for CM-FX6 kernel. You can create a copy of Linux git tree or download a snapshot and extract it. We assume that you have created /home/development/cm-fx6/kernel directory for CM-FX6 kernel development.
Snapshot download
- Download v3.0.35 snapshot with your web browser.
- Extract the downloaded archive linux-3.0.35.tar.bz2
cd /home/development/cm-fx6/kernel tar xvf /path/to/downloaded/linux-3.0.35.tar.bz2 mv linux-3.0.35 linux-cm-fx6
- This will create /home/development/cm-fx6/kernel/linux-cm-fx6 directory containing Linux kernel tree.
- Apply the CM-FX6 patch
cd /home/development/cm-fx6/kernel/linux-cm-fx6 patch -p1 < /path/to/cm-fx6-linux/kernel/linux-3.0.35-cm-fx6-6.4.patch
Git clone
- Install git version control system.
- Create a clone of Linux kernel tree
cd /home/development/cm-fx6/kernel git clone git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-cm-fx6
- Create a branch for CM-FX6 development. The CM-FX6 patches are generated vs. v3.0.35 tag (839cf7a236278ae358ff12141a168c0982fa0cd9 commit) in the linux-stable tree. It is recommended to use exactly the same baseline to avoid merge conflicts.
git checkout -b cm-fx6-dev v3.0.35
- Apply the CM-FX6 patch
cd /home/development/cm-fx6/kernel/linux-cm-fx6 git apply /path/to/cm-fx6-linux/kernel/linux-3.0.35-cm-fx6-6.4.patch
Building the kernel
export ARCH=arm
export CROSS_COMPILE=arm-none-linux-eabi-
make cm_fx6_defconfig
make menuconfig
make && make uImage && \
INSTALL_MOD_PATH=/home/development/cm-fx6/rootfs make modules_install
In the example above, the Linux kernel image (uImage) will be created in /home/development/cm-fx6/kernel/linux-cm-fx6/arch/arm/boot, and the loadable kernel modules will be installed into the /home/development/cm-fx6/rootfs/lib/modules directory.
When the CM-FX6 is booted with the kernel image created as described above and with networked root filesystem at /home/development/cm-fx6/rootfs/, the system will be able to load the kernel modules properly, thus avoiding module version problems.
Basic platform support
The CM-FX6 basic platform support is implemented in the arch/arm/mach-mx6/board-cm-fx6.c file of Linux kernel source tree. This file includes default setup of multi-functional pins, registration of the devices integrated in the CM-FX6 module and definitions of platform-specific configuration for these devices.
LCD, DSI, DVI, HDMI and LVDS support
CM-FX6 module can be used with five display interfaces: LCD, DSI, DVI, HDMI and LVDS. CM-FX6 Evaluation Kit is equipped with the Startek KD050 / Hannstar HSD050 LCD touch panel and it is used as the default video output device. LCD, DSI and DVI are sharing the same display interface (DI0) and therefore only one of them can be used at the same time. HDMI and LVDS use other display interfaces and therefore can be used at the same time with each other and with either DVI, DSI or LCD interfaces.
Image Processing Unit (IPU)
In the kernel configuration menu choose Device Drivers ---> MXC support drivers submenu and enable:

- Since TRULY MIPI WVGA Panel is not the default LCD, there is a special kernel command line argument required:
cm_fx6_lcd=truly
DVI
For the DVI interface to function properly, either LCD or DVI should be attached at the same time.
The following kernel parameter must be appended to the kernel command line:
video=mxcfb0:dev=dvi,1280x800M-32@50,if=RGB32
HDMI
In the kernel configuration menu choose Device Drivers ---> Graphics support submenu and enable:
- MXC HDMI driver support

In the default configuration the second frame buffer is routed to the HDMI interface. Therefore to use the HDMI on the second frame buffer, no special kernel arguments are required. For routing the first frame buffer to the HDMI interface, the following kernel parameter must be appended to the kernel command line:
video=mxcfb0:dev=hdmi,1920x1080M-32@50,if=RGB32
LVDS

LVDS0
In the default configuration the third frame buffer is routed to the LVDS0 interface. Therefore to use the LVDS0 on the third frame buffer, no special kernel arguments are required.
For routing the first frame buffer to the LVDS0 interface, the following kernel parameter must be appended to the kernel command line:
video=mxcfb0:dev=ldb,1366x768M-18@60,if=RGB666
LVDS1
In the default configuration the fifth frame buffer is routed to the LVDS1 interface. Therefore to use the LVDS1 on the fifth frame buffer, no special kernel arguments are required.
|
The LVDS1 port can't be routed to the first frame buffer using the kernel video parameter. |
Touchscreen controllers support
CM-FX6 Evaluation Kit has two separate touch screen controllers: Himax (HX8520-C/HX8526-A) (assembled on the DataImage LCD) and TI TSC2046 (on-board of the CM-FX6 module). The Himax is a multi touch capacitive touchscreen connected to the I2C1 bus of the CM-FX6 module. The TI TSC2046 is a resistive touchscreen controller conneted to the SPI1 bus of the CM-FX6 module. To use the TI TSC2046 controller, the resistive touchscreen must be connected to one of the interfaces on the SB-FX6 base board.
Himax touchscreen controller
In the kernel configuration menu choose Device Drivers ---> Input device support ---> Touchscreens submenu and enable:
- Himax touchscreen support

Controller–area network (CAN) support
The Flexible Controller Area Network (FLEXCAN) module is a communication controller implementing the CAN protocol according to the CAN 2.0B protocol specification [Ref. 1]. The CAN protocol was primarily designed to be used as a vehicle serial data bus meeting the specific requirements of this field: real-time processing, reliable operation in the EMI environment of a vehicle, cost-effectiveness and required bandwidth. The FLEXCAN module is a full implementation of the CAN protocol specification, which supports both standard and extended message frames. 64 Message Buffers is supported.
To enable CAN functionality of CM-FX6, the following dependencies must be met:
- CAN bus subsystem support enabled
- Raw CAN Protocol support enabled
- Broadcast Manager CAN Protocol support enabled
- Platform CAN drivers with Netlink support
- CAN bit-timing calculation enabled
- Support for Freescale FLEXCAN based chips enabled
CAN bus subsystem support
In the kernel configuration menu choose Networking Support submenu and enable CAN bus subsystem support. You can choose to either build it into the kernel or to compile it as a module. In the last case the module name will be can.
