Building Yocto branch rocko for board poplar I got this errors:

@shawnguo2 can you confirm the u-boot branch to use?

[shawnguo2]

https://github.com/96boards-poplar/u-boot latest https://github.com/96boards-poplar/linux poplar-4.9

[fboudra]

@shawnguo2 Thanks. @clopez Please adjust your PR accordingly. U-Boot branch should be latest instead of alex/latest.

@shawnguo2 Thanks. @clopez Please adjust your PR accordingly. U-Boot branch should be latest instead of alex/latest.

Sorry, there referenced commit can only be found on the branch alex/latest

$ git clone https://github.com/96boards-poplar/u-boot 
[...]
$ cd u-boot
$ git branch -a
$ git branch -a
  * latest
    remotes/origin/HEAD -> origin/latest
    remotes/origin/alex/latest
    remotes/origin/latest
    remotes/origin/shawn/install

The referenced commit on the u-boot bitbake recipe is 98469ebb7afaacc742d6f651f8e676e755672a63 and git says this

$  git branch -a --contains 98469ebb7afaacc742d6f651f8e676e755672a63
   remotes/origin/alex/latest

@clopez You can keep using 'alex/latest' branch with the commit in the boot recipe, but we are not going to update the branch any more. Instead, branch 'latest' is the one we are currently maintaining and updating. So you are suggested to update the boot recipe to use the HEAD of this branch.

That's a different history.

This patch only fixes the references to the repositories and allows Yocto to fetch those commits. With this patches It builds fine, otherwise a fetch error will happen.

But this patches doesn't update the reference commit that will be built. If you want to update the recipe to use a different commit feel free to do that in a follow-up commit. I won't do that as I can't currently test that what I have built runs ok because I don't know how to flash the built products I got. See: https://github.com/96boards-poplar/Documentation/issues/4

@clopez make sense. I'd like to move to latest so I'll do a follow up commit.
