Yocto and IMX 6 Element14 devlopment kit

Former Member
Former Member over 12 years ago

Good morning,

 

     I just received my IMX 6 Element 14 devlopment Kit and I try to put some free linux on it. My goal is to use the 2D and 3D graphical card's acceleration. So I try first to build the sabre_lite yocto image as in the thread ( https://community.freescale.com/docs/DOC-93844 ). Well it build well on a Fedora 16. And with the original q_bootscripts of the timesys image it start booting on my kit. I have to change the partition of the SD Card but it works. So I was then very glad, evrything was smooth and work well. But ... Then I try to plug a keyboard on the kit, and I ve got some error ( kernel panic ) during the boot and the boot stop, perhaps udev can't handle the keyboard during the boot ?  I've try to get the network working but the kernel stop too.

If plug after the boot the keyboard works well and there's no kernel panics. So it's just during the initial boot.

 

So are there people who succeded to boot the yocto image with this element14 kit ? Or the prefered free are just lbit and linearo ?

 

My next step will probably be to update the u-boot and to try the lbit / linearo image.

But it will be very helpfull to know if there was some people which succeded with yocto( and how they have done it ). Yocto seem's to be the freescale prefered linux distribution, and well it's seem very cool.

 

Thanks,

    Thank you nass!

     

    We provided feeback yesterday . However we recompiled  the new branch( dylan) and we can say the same like here : Dylan works perfectly!

     

    I'm going to write to Daiane in https://community.freescale.com/docs/DOC-9384  explaining what happened to us.

     

    Note :  We used the u-boot made by Yocto and it works fine. We just added the next secuence (we use an HDMI-DVI ADAPTER CABLE) :

    setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=${mmcroot} video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24'

     

    Important: this u-boot is using the SD connector , not the TF ( micro-sd )connector. If you want to use the TF  you must to change the value of the mmcdev variable (  mmcdev=1)!

    u-boot by yocto?

    is it an rpm package?

    how did you go about installing the new u-boot?

    thank you.
