OpenEmbedded/Yocto for UDOO Boards

I use windows and linux tomorrow i can send you this informations !

 

Hi graugans, very goog job, the M4 works now just a point to verify-> your script create the folder /var/opt/M4 but i need to put manually the file m4last.fw (tested 2 times, erase and dd sdcard) afeer that it works very well. Tested with arduino ide under win7 and linux !

the path for windows is :

Code:

C:\Users\YOUR_USER\AppData\Roaming\Arduino15\packages\UDOO\hardware\solox\1.6.5

 

No problem, i will do this in future ...

let me know if it's that you want https://github.com/graugans/meta-udoo/issues/3

 

After a little test, lvds7 inchs work, just need to add some adjustment (see git issues). About Qt, touch not working for the moment (with lvds7). Serial com between M4 and A9 works ... I will begin a little tutorial with qt now ...

 

Hi, i would like to enable espci2 (A9 side) that is disabled for the moment :

from imx6sx-udoo-neo-externalpins.dtsi in : udoo-community-bsp/neoBuild/tmp/work/udooneo-poky-linux-gnueabi/linux-udooboard/3.14.56-r0/git/arch/arm/boot/dts/

&ecspi2 {
fsl,spi-num-chipselects = <1>;
cs-gpios = <&gpio6 14 0>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_ecspi2>;
status = "disabled";
};

I suppose i have just to write

status = enabled

but how i can recompile kernel from yocto ?

 

@graugans/modjo
Thank you for the excellent guide. I started from scratch by installing ubuntu 14.04 and by following you tutorial it worked fine until i started to cross compile the QT5 SDK. I am getting the below error: Did you guys face such issue??

Hi, i didn't remember to have this issue but my local.conf (and bblayers) are different from the git --> i had some modules to have a full qt5 image ! I can post this evening my conf ...

 

@graugans: I am using udoo quad. I was thinking about this and wondering if I would first have to install QT natively on my Ubuntu 14.04? Did you guys have this installed on your system before building the tool chain? I ask this because the recipe seems to be looking for some libraries that are missing

My local.conf
My bblayers.conf

 

Will try this out [emoji106]

@modjo: I used the conf files you provided, but this time it fails while building the image itself. Below is the error. Did you face this issue?

Hi i didn't remember to have this error, normally now they have all the patch to build qtwebengine ! did you make a bitbake -c cleanall udoo-image-qt5.bb before your build ? Sometimes when i have too many errors i make a big clean of my yocto package (tmp folder ...) and restart a build ! Perhaps you can try to build the image for the moment without qtwebengine (and add it after), to do this remove
qtwebengine \
qtwebengine-qmlplugins \
from local.conf

 

Thanks a lot for your great tuto ! It worked for me with Qt5.
