Hi,
I'm using Ubuntu 18.04.2 LTS (having recently upgraded from Ubuntu 14.04 LTS) and set my environment up like this:
(Install pre-requisites)
> mkdir fsl
> cd fsl
> repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b pyro
> repo sync
> mkdir build
> MACHINE=nitrogen6x DISTRO=poky source setup-environment build
> bitbake core-image-minimal
Build completed with no errors and 3 warnings about a missing item but it tried a mirror site and found it there.
> cd build/tmp/deploy/images/nitrogen6x
<insert SDCard - appears as /dev/sdb>
> gunzip -c core-image-minimal-nitrogen6x-20190626151810.rootfs.sdcard.gz | sudo dd of=/dev/sdb bs=4M

> sync
Remove SDCard and insert it into the target and power on. In the terminal window, I get:

My questions/comments are:
1) I previously used Ubuntu 14.04 with Yocto version Dylan and that produced an SDCard which booted perfectly for many years on my target. We've recently updated to Ubuntu 18.04 and Dylan no longer builds. In fact, I tried all versions of Yocto incrementally form Dylan and Pyro was the first one that would build on Ubuntu 18.04.
2) The SDCard image looks a little small - I was expecting around 3G for the entire image.
3) What have I done wrong?
4) Does Yocto no longer build the latest version of uBoot?
TIA,
