QorIQ SDK v2.0-1703 Documentation

Gettings Started-> Essential Build Instructions:

-> Install SDK 2.0

Note: To avoid a long time build, you can install the source ISO and the cache ISO in the same installation folder.

1. Mount: (On Ubuntu/Mint to mount ISO is sufficient to click on the iso file)

QorIQ Linux SDK v2.0 SOURCE.iso

QorIQ Linux SDK v2.0 PPC64E6500 Yocto Cache.iso ( precompiled builds)

2. As a non-root user, install Yocto Project

run install from sdk source mounted dir

• cd <sdk source mounted dir/
• ./install

run install from yocto cache mounted dir to the same installation dir

• cd <yocto cache mounted dir>
• ./install

->Install SDK V2.0-1703

Install the incremental update SDK-V2.0-1703.tar.bz2

Untar the file in your preferred temporary dir:

tar -xjf /home/roby/Scaricati/QorIQ\ Linux\ SDK\ v2.0-1703.tar.bz2 cd <temporary dir>

Launch install ( when requested give the same installation dir )

./SDK-V2.0-1703/install

->Set Up Host Environment

With linux Mint the python default version is 2.7 as requested ( to verify your default python --version )

Install needed gnu/linux packages relatad to your distro

->Set Up Poky

cd <installation dir>  ( cd QorIQ-SDK-V2.0-20160527-yocto/ )<br>
. ./fsl-setup-env -m t2080rdb-64b

Update kernel source

cd QorIQ-SDK-V2.0-20160527-yocto/sources/meta-nxp-npi-1703/recipes-kernel/linux/<br>
git pull origin jethro-sdk-v2.0-ga-17.03

Set T2080RDB to boot from SD card

As Documented in

in 4.4.18.3 Switch Settings

SD Flash boot
SW1 [1:8] = 0010 0000
SW2 [1:8] = 0011 1111
SW3 [1:8] = 1110 0001

Working on SD card

Insert an sdcard on your Ubuntu machine ( for example /dev/sdc )

mount sdcard, go to the boot directory of the sdcard

cd boot

All custom compiled uboot,kernel images and rootfs are inside:

QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/

Copy kernel image to sdcard

Kernel image are two files .dtb and uImage

 
<code>cd boot</code>


sudo cp QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/uImage-t2080rdb.dtb ./uImage.dtb  <br>
sudo cp QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/uImage .

uncompress modules on sdcard root

cd <root sdcard><br>
sudo tar zxvf QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/modules-t2080rdb-64b.tgz

Modify U-boot

cd QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b <br>
cd tmp/work/t2080rdb_64b-fsl-linux/u-boot-qoriq/2016.09+fslgit-r0/git/include/configs

modify configs files as T208xRDB.h

Compile U-boot

cd QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b<br>
bitbake -c compile -f u-boot <br>
bitbake u-boot

Copy uboot for to sdcard

warning: change /dev/sdc with your sdcard dev

sudo dd if=~/software/QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b/tmp/deploy/images/t2080rdb-64b/u-boot-sdcard.bin of=/dev/sdc seek=8 bs=512

Prepare a custom yocto images

example: core-image-x11 for X11 packages

cd QorIQ-SDK-V2.0-20160527-yocto . ./fsl-setup-env -m t2080rdb-64b bitbake core-image-x11

QorIQ-SDK-V2.0-20160527-yocto/build_t2080rdb-64b $

cd tmp/deploy/images/t2080rdb-64b/

you find a *.rootfs.ext2.gz.u-boot file

From rootfs .u-boot file to extracted in sdcard

Transform rootfs.ext2.gz.u-boot file to .gz

if=core-image-x11-t2080rdb-64b-20170715152753.rootfs.ext2.gz.u-boot of=core-image-x11-t2080rdb-64b.rootfs.ext2.gz bs=64 skip=1

Extract .gz to .ext2

gunzip core-image-x11-t2080rdb-64b.rootfs.ext2.gz

Rename .ext2 to .iso

mv core-image-x11-t2080rdb-64b-20170715152753.rootfs.ext2 core-image-x11-t2080rdb-64b-20170715152753.rootfs.ext2.iso

Mount .iso

Romove all files on sdcard except boot folder

Copy mounted iso cotent to sdcard root

cp -rp <mounted iso dir> to sdcard root

Create file kernel modules dependencies

go to kernel module directory of the generated sdcard with Yocto

cd /lib/modules/4.1.35-rt41 edit /lib/modules/4.1.35-rt41/modules.dep
