2.2.9

Linux kernel

This section provides the detailed information and process for building the kernel images.



Open a terminal window and change the directory to yocto setup path.

$cd ~/<path to iwg15-release-bsp>/iwg15-release-bsp/



To setup environment build path, execute the below command. This is required only once on switching of

every new terminal window.

$MACHINE=imx6qdl-iwg15-q7 source setup-environment build_iwg15



To compile the Linux kernel, execute the below command.

$bitbake linux-iwg15



To change the Linux kernel configuration, execute the below command.

$bitbake -c menuconfig linux-iwg15



To re-build Linux kernel from scratch, execute the below commands.

$bitbake -f -c compile linux-iwg15



After the successful compilation the zImage will be placed in below path.

~/<path to iwg15-release-bsp>/iwg15-release-bsp/build_iwg15/tmp/work/imx6qdl_iwg15_q7-poky-

linux-gnueabi/linux-iwg15/4.1.15-r0/build/arch/arm/boot/



The dtb files will be placed in below path.

~/<path to iwg15-release-bsp>/iwg15-release-bsp/build_iwg15/tmp/work/imx6qdl_iwg15_q7-poky-

linux-gnueabi/linux-iwg15/4.1.15-r0/build/arch/arm/boot/dts/



The binary files are listed below

zImage

dts/imx6*-iwg15m-q7*.dtb



Refer the BINARY PROGRAMMING section to update the Linux kernel binary.



Refer the Device tree source description section for device tree source code organization.

2.3

BSP Standalone compilation

Yocto can be used to extract and build the u-boot source/ linux kernel source. The following steps will help to build

the u-boot source code / linux kernel directly for iW-RainboW-G15M-Q7 platform.



Before compiling the source code cross compiler should be installed to “/opt” directory of host machine if it

is not present.



Refer the Cross-compiler build section to install the cross-compiler.
