[Yocto] VB Build on Ubuntu 20.04

my BeagleV-aHead is on it’s way, so while I wait, I was going to build the images in a VirtualBox with Ubuntu 20.04
following direction at

everything went fine down to “Starting Build” then

there are more errors, but lets start with these two

I saw this same issue a few times, never really found a good solution, i had better luck upgrading distro:

Since your on a VM, use Debian Bullseye instead, it’s what works best for me now, and is the default ci backend: .gitlab-ci.yml · Linux_SDK_V1.1.2-light-beagle · BeagleV-Ahead / xuantie-yocto · GitLab

For reference, here is the whole docker file, for package hints for you VM…

if i issue “bitbake -k thead-image-linux” again, i get the following

ERROR: Nothing RPROVIDES ‘ap6203’ (but /home/amf/devel/beagleV/xuantie-yocto/meta-light/recipes-core/images/thead-image-linux.bb RDEPENDS on or otherwise requires it)
ap6203 was skipped: incompatible with machine light-a-val (not in COMPATIBLE_MACHINE)
NOTE: Runtime target ‘ap6203’ is unbuildable, removing…
Missing or unbuildable dependency chain was: [‘ap6203’]
ERROR: Nothing RPROVIDES ‘thead-image-linux’
No eligible RPROVIDERs exist for ‘thead-image-linux’

using debian11, bullseye, it now builds
however, there is no ‘deploy’ directory in ‘tmp-glibc’ directory

any idea on this ?

MACHINE=light-beagle bitbake -k thead-image-linux

finally got it to build with a deploy directory and all it’s content.
Are there instructions or script to create an sdcard image ??

Directions for flashing the onboard eMMC is at the bottom of: readme.md · Linux_SDK_V1.1.2-light-beagle · BeagleV-Ahead / xuantie-yocto · GitLab

Directions for creating a bootable microSD have not been provided by the vendor.

I managed to get the yocto image building on PopOS 22.04 which is based on ubuntu, with a small patch to llvm based on an issue building with gcc11.

My fix is based on someone else posting a similar error and their already being a patch Compiling Cling error: ‘numeric_limits’ is not a member of ‘std’ - Cling - ROOT Forum

The llvm change is here ⚙ D89450 llvm/utils/benchmark: add missing <limits> inclusion

I signed up to the beagle gitlab but haven’t had time to figure out how to submit a change.

Hope this helps others.

Oh what’s your git.beagleboard.org user name… for spam/ci/etc protection, first time users are disabled, and i need to just check a click box, in your user profile…

My username is wolfeidau, i just signed up today.


and all set, you can fork, push, use ci etc. :wink:
