Linux: Upload the original YOCTO source code to github

Be sure you start with empty meta-openrex (no patches inside). Run this to get clean starting source code. Run this:

cd ~/fsl-community-bsp/ //run this command in case bitbake is not found, otherwise you don't have to run it

source setup-environment build //run this command in case bitbake is not found, otherwise you don't have to run it

cd ~/fsl-community-bsp/build/

bitbake -c clean linux-fslc-imx

bitbake -c compile -f linux-fslc-imx

bitbake core-image-minimal

We need to do a small correction for github. Delete the old .git:

cd ~/fsl-community-bsp/build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-fslc-imx/3.14-1.1.x+gitAUTOINC+327d5c9063-r0/git/

rm -rf .git

and edit .gitignore

nano .gitignore

Go on the end of the file and add following line (a folder .pc/ is added during applying patches and we dont want to have it in github):

/.pc/*

We need to upload the original YOCTO Kernel source code to github. Create a new repository and put it there.

cd ~/fsl-community-bsp/build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-fslc-imx/3.14-1.1.x+gitAUTOINC+327d5c9063-r0/git/

git init

git add .

git commit -m 'Initial version'

git remote add origin https://github.com/FEDEVEL/openrex-linux-3.14.git

git push -u origin master

I normally also create a branch:

git branch jethro

git push origin jethro

Change to the branch 'jethro':

git checkout jethro

Linux: How to add support for OpenRex (Or your custom board)

Very often, there are differences between software versions. Therefore, there are no general instruction how to add custom support into the software. You may need to figure out by yourself what everything has to be changed and added to support a new board. One of the ways how to do it, is to search for files with your reference board name. For example, in our case we look for "sabresd".

cd ~/fsl-community-bsp/build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-fslc-imx/3.14-1.1.x+gitAUTOINC+327d5c9063-r0/git/

grep -r "sabresd"

Here are the results:

Set the compiler:

export CROSS_COMPILE=arm-linux-gnueabihf-

export ARCH=arm

Try if you can compile linux without any changes:

make clean

make imx_v7_defconfig

make -j4 zImage imx6q-sabresd.dtb

Adding support for a new custom board

Edit: "arch/arm/boot/dts/Makefile" Find "imx6q-sabresd" and add:

imx6q-openrex.dtb \

This is how it will look

imx6q-sabresd-hdcp.dtb \

imx6q-openrex.dtb \

imx6q-sbc6x.dtb \

Edit: "arch/arm/boot/dts/imx6q-openrex.dts"

cp arch/arm/boot/dts/imx6q-sabresd.dts arch/arm/boot/dts/imx6q-openrex.dts

gedit arch/arm/boot/dts/imx6q-openrex.dts

Replace

#include "imx6qdl-sabresd.dtsi"

with

#include "imx6qdl-openrex.dtsi"

Edit: "arch/arm/boot/dts/imx6qdl-openrex.dtsi" You may noticed that imx6q-openrex.dts calls imx6qdl-sabresd.dtsi. Let's create it for openrex:

cp arch/arm/boot/dts/imx6qdl-sabresd.dtsi arch/arm/boot/dts/imx6qdl-openrex.dtsi

gedit arch/arm/boot/dts/imx6qdl-openrex.dtsi

You may need to have a look also inside "arch/arm/mach-imx/mach-imx6q.c". There is something about sabresd, but we don't need to edit it, at least not now.

Linux: Compile

That's it. Try to compile our new custom board:

make clean

make imx_v7_defconfig

make -j4 zImage imx6q-openrex.dtb

*Note: If you get error "piggy.lzo Error" just install lzop. Run "sudo apt-get install lzop".

The output files are located at:

arch/arm/boot/zImage

arch/arm/boot/dts/imx6q-openrex.dtb

Now the hard part. You will need to go through "arch/arm/boot/dts/imx6q-openrex.dts" and "arch/arm/boot/dts/imx6qdl-openrex.dtsi" files and correct them. Advice: After some changes always try to recompile, and check if you have not changed/removed something critical.

How to edit dts / dtsi files?

Go through the files, remove the peripherals you don't need and correct pin assigment. For example: Original

pinctrl_ecspi1: ecspi1grp {

fsl,pins = <

MX6QDL_PAD_KEY_COL1__ECSPI1_MISO 0x100b1

MX6QDL_PAD_KEY_ROW0__ECSPI1_MOSI 0x100b1

MX6QDL_PAD_KEY_COL0__ECSPI1_SCLK 0x100b1

>;

};

Go to our schematic and have a look where CSPI1_MISO is connected. You can see it's GPIO3_IO17. Go to arch/arm/boot/dts/imx6q-pinfunc.h and search for "GPIO3_IO17". You will find "MX6QDL_PAD_EIM_D17__GPIO3_IO17" ... we would like to work this pin in MISO mode, so select "MX6QDL_PAD_EIM_D17__ECSPI1_MISO" and paste it into dtsi file. It will look then:

pinctrl_ecspi1: ecspi1grp {

fsl,pins = <

MX6QDL_PAD_EIM_D17__ECSPI1_MISO 0x100b1

MX6QDL_PAD_KEY_ROW0__ECSPI1_MOSI 0x100b1

MX6QDL_PAD_KEY_COL0__ECSPI1_SCLK 0x100b1

>;

};

Do it for all the pins. If you are not sure where the pin from reference board is connected, search through reference schematic.

Linux: Useful stuff

Board related files

gedit arch/arm/boot/dts/imx6q-openrex.dts

gedit arch/arm/boot/dts/imx6qdl-openrex.dtsi

File where you can find default configuration:

gedit arch/arm/configs/imx_v7_defconfig

File where you can find pin names:

gedit arch/arm/boot/dts/imx6q-pinfunc.h

Linux: Try the compiled Kernel

Copy the files to /tftp directory

cp arch/arm/boot/zImage /tftp/zImage-imx6q-openrex

cp arch/arm/boot/dts/imx6q-openrex.dtb /tftp/imx6q-openrex-dtb

Now, be careful. It is important, that your uBoot environment variables are set correctly. If an important parameter is missing, something may not work (for example ethernet may not work or Linux will freeze at Starting Linux .....).

Here is example of uBoot parameters from working uBoot 2014. You may find them useful (they work also with uBoot 2015):

setenv baudrate '115200'

setenv boot_fdt 'try'

setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=${mmcroot}'

setenv mmcboot 'echo Booting from mmc ...; run mmcargs; if test ${boot_fdt} = yes || test ${boot_fdt} = try; then if run loadfdt; then bootz ${loadaddr} - ${fdt_addr}; else if test ${boot_fdt} = try; then bootz; else echo WARN: Cannot load the DT; fi; fi; else bootz; fi;'

setenv mmcdev '0'

setenv mmcpart '1'

setenv mmcroot '/dev/mmcblk2p2 rootwait rw'

setenv netargs 'setenv bootargs console=${console},${baudrate} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp'

setenv netboot 'echo Booting from net ...; run set_ethernet; run netargs; tftp ${tftp_dir}/${image}; if test ${boot_fdt} = yes || test ${boot_fdt} = try; then if tftp ${fdt_addr} ${tftp_dir}/${fdt_file}; then bootz ${loadaddr} - ${fdt_addr}; else if test ${boot_fdt} = try; then bootz; else echo WARN: Cannot load the DT; fi; fi; else bootz; fi;'

setenv script 'boot-imx6q-tinyrex.scr'

setenv set_ethernet 'if test ${ethaddr}; then; else setenv ethaddr 00:0D:15:00:D1:75; fi; if test ${ipaddr}; then; else setenv ipaddr 192.168.0.150; fi; if test ${serverip}; then; else setenv serverip 192.168.0.1; fi; if test ${netmask}; then; else setenv netmask 255.255.255.0; fi'

setenv spics 'CONFIG_ENV_SPI_CS'

setenv spidev 'CONFIG_ENV_SPI_BUS'

setenv stderr 'serial'

setenv stdin 'serial'

setenv stdout 'serial'

setenv tftp_dir 'imx6'

setenv uboot 'u-boot-imx6q-tinyrex.imx'

setenv update_fdt 'run set_ethernet; run update_set_filename; if mmc dev ${mmcdev}; then if tftp ${tftp_dir}/${upd_fdt}; then fatwrite mmc ${mmcdev}:${mmcpart} ${loadaddr} ${fdt_file} ${filesize}; fi; fi'

setenv update_kernel 'run set_ethernet; run update_set_filename; if mmc dev ${mmcdev}; then if tftp ${tftp_dir}/${upd_kernel}; then fatwrite mmc ${mmcdev}:${mmcpart} ${loadaddr} ${image} ${filesize}; fi; fi'

setenv update_script 'run set_ethernet; run update_set_filename; if mmc dev ${mmcdev}; then if tftp ${tftp_dir}/${upd_script}; then fatwrite mmc ${mmcdev}:${mmcpart} ${loadaddr} ${script} ${filesize}; fi; fi'

setenv update_set_filename 'if test ${upd_uboot}; then; else setenv upd_uboot u-boot-imx6q-tinyrex.imx; fi; if test ${upd_kernel}; then; else setenv upd_kernel zImage-imx6q-tinyrex; fi; if test ${upd_fdt}; then; else setenv upd_fdt imx6q-tinyrex.dtb; fi; if test ${upd_script}; then; else setenv upd_script boot-imx6q-tinyrex.scr; fi'

setenv update_uboot 'run set_ethernet; run update_set_filename; if mmc dev ${mmcdev}; then if tftp ${tftp_dir}/${upd_uboot}; then setexpr fw_sz ${filesize} / 0x200; setexpr fw_sz ${fw_sz} + 1; mmc write ${loadaddr} 0x2 ${fw_sz}; fi; fi'

In our case, I had to add following parameters to be able to boot Linux:

setenv fdt_addr '0x18000000'

setenv fdt_high '0xffffffff'

saveenv

To test our Linux (it will not fully boot up, we do not have file system yet), run:

tftp 0x10800000 zImage-imx6q-openrex

tftp 0x18000000 imx6q-openrex-dtb

bootz 0x10800000 - 0x18000000
