In case you have updated Kernel and uploaded changes to github, you have to update also meta-openrex. #SRCREV is the commit number, must be always changed for a new version Run set_ethernet run update_set_filename sata init tftp $" In case you boot from SATA, you can use these commands: In case you run OpenRex from SD card, switch on your OpenRex board, go to uBoot and run following commands: Gedit arch/arm/boot/dts/im圆qdl-openrex.dtsiĬp arch/arm/boot/zImage /tftp/im圆/zImage-im圆q-openrexĬp arch/arm/boot/dts/im圆q-openrex.dtb /tftp/im圆/im圆q-openrex.dtb The path may look like this:Ĭd ~/fsl-community-bsp/build-openrex/tmp/work/im圆q_openrex-poky-linux-gnueabi/linux-openrex/3.14-r0/git
#U boot source code#
Usualy the Kernel source code is located inside your build directory. Option 2: Find Kernel source code located inside your YOCTO project
Option 1: Get the Kernel source code from github
#U boot source download#
You can download it directly from github or you can edit the Kernel files in your YOCTO OpenRex project. You have two options to get the source code. Git commit -m 'Fixed SD card: CD and RW pin definition' //use a comment describing the changes
if you are happy with the differences, upload the changes to github in case differences are not what you expected or you find a mistake, you can use "git reset". Git diff origin/jethro //check if it shows correct differences " wants to upload also files which you have not changed, that's why I use "git add filename" based on the status command, add the files you would like to upload to github Git status //have a look what files were changed Git branch //check if you are on jethro branch Git checkout jethro //set the current active branch to jethro git remote set-url origin //run this if you get error, that "git://" is read only git remote add origin //run this if you get error about no origin Git remote -v //check the origin, should point to your github When you are happy with the new uBoot, run following commands to update uBoot github: Setenv serverip 192.168.0.37 //use your Linux host IP *Note: If you have updated environmental variables inside uBoot source code, after you reboot uBoot, you may want to run: In case you would like to update it manually, here are the commands: Switch on your OpenRex board, go to uBoot and run following command: *Note: If you get error like "lib/asm-offsets.c:1:0: error: bad value (armv5) for -march= switch", then run the "Select cross compiler" again (these are the commands "export CROSS_COMPILE=." and "export ARCH=arm") Reflash uBoot Gedit board/fedevel/m圆openrex/m圆q_4x_mt41j256.cfgĬp u-boot.imx /tftp/im圆/u-boot-im圆q-openrex.imx Gedit board/fedevel/m圆openrex/m圆openrex.c Here are the files what we normally edit: If you do not have any compiler installed (or you are not sure)Įxport CROSS_COMPILE=arm-linux-gnueabihf-Įxport CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/arm-none-linux-gnueabi.
