[meta-freescale] Freescale Yocto Question - Building imx6dl-riotboard

Fri Nov 18 14:07:27 PST 2016

Hi Nikolay & Daiane, let me know your results when you test.
Daiane, you were correct that I was not building from the community-bsp-platform. Today I built the fsl-image-machine-test image from github.com/Freescale/fsl-community-bsp-platform's krogoth branch, for the imx6dl-riotboard. The results were the same, where the hardware does not boot or show any debug kernel/bootloader messages in the terminal.

I noticed that the fsl-community-bsp repo and it's metadata layers appeared to have no DISTRO or configuration options for fb, x11, wayland, etc. So I used the standard poky distro. 

Thank you both again for looking into this.
-Eric Zaluzec

[1] But once the device is powered on, the debug terminal is blank and I do not see any kernel output logs, boot messages, or the freescale splash screen. Additionally, I built and tested the fsl-image-gui with x11 distro. Same results on RIoTboard.

From my understanding there is only a solo RIoTboard. What made the naming convention change so much from solo to dual lite?

As far as I remember, DL was used for all solo & dual-lite socs.

I can give it a spin during the weekend, hope it's not too late.
