Known good setup

[mbrooksx]

Hi Mirza,

Thanks for implementing this! I'm trying to get a basic setup where I can test the latest ML release (as you have in a bug, pulling from GitHub). The README mentions using the Master branches for my manifest but I see you have bugs in Zues.

Should I expect this to work at master? If not, should I be using warrior? On master I see coral layer concerns (without adding dunfell to layer.conf compat) as well as dtc-145 issues in u-boot-coral_2017.03.bb (and I'm still slogging through to try to get it all working).

Thanks!

Hi @mbrooksx ,

I would recommend using the warrior branch which is the current stable release. Also check out the wiki which covers some additional steps to get all components in place and how to run the example models.

master branch is currently WIP and primary trying to get master to work together with zeus to get a working zeus branch before starting to work on dunfell.

Hi @mirzak ,

Thanks - I'm able to boot the board with warrior (I was attempting warrior for FSL and master for meta-coral, cause a lot of bbappend mismatch).

Sorry for the newbie questions, one last issue I'm having is getting the python packages (and specifically I'd like to see python3-edgetpu) in action. However I noticed that the packages are excluded:

DEBUG: EXCLUDE FROM WORLD: virtual:nativesdk:/usr/local/google/home/michaelbrooks/yocto_warrior/sources/meta-coral/recipes-support/python/python3-edgetpu.bb
DEBUG: EXCLUDE FROM WORLD: virtual:native:/usr/local/google/home/michaelbrooks/yocto_warrior/sources/meta-coral/recipes-support/python/python3-edgetpu.bb

I can't find the reason why (I'm make core-image-base, but the same with weston) - perhaps license mismatch for Apache?

Thanks again!

Can you share a bit more about your environment? I have not seen similar problems when testing

[mbrooksx]

I'm running Debian, it's a Stretch derivative (designed for Google employees, I'm on the Coral team) on a 5.2 kernel. I followed the steps listed on the warrior branch, initializing the repo with the warrior manifest then checking out clang and coral with the warrior branches. Nothing else is changed (with the exception of skipping the sanity test since it doesn't like my access permissions despite matching the u+rwx and a+rx request).

Thanks!

[mirzak]

Would it be possible to share a more complete log? Do not have much to go on and nothing wrong with your environment.

I do not know what type of permissions errors you have, but e.g running bitbake with sudo would probably mess things up pretty bad and best would be to start over.

Haven't been running with sudo, permissions are correct just can't convince the sanity checker of it.

The logs look good to me, can you share the output of

cat tmp/deploy/images/coral-dev/core-image-base-coral-dev.manifest

It should contain the python3-edgetpu if you added it trough IMAGE_INSTALL by e.g putting the following in your local.conf file

IMAGE_INSTALL_append = " \
    python3-edgetpu \
    python3-edgetpu-examples \
"

The EXCLUDE FROM WORLD: should not really matter, as you are not running a world build.

Another way to debug what you have in your IMAGE_INSTALL is e.g,

bitbake core-image-base -e | grep ^IMAGE_INSTALL

This is a good way to make sure that your desired changes actually are being applied.

Thanks that was really useful. I copied the recipe on another bug to make a fsl-multimedia-full with edgetpu added. Unfortunately in the last week since I was first building there now appears to be issues with the GPT on the WIC image but I think we can close this bug. Thanks agian!
