[meta-raspberrypi][Question] How to build an hwup image for raspberrypi3

[piotr.lewicki]

Hello,
I'm trying to build a Yocto image for raspberrypi3.
I'm using only two layers:
- poky (krogoth: rev eff84a76acea1a0842194106a66684511f409842)
- meta-raspberrypi (master: rev 9912d38e97671704822d1aa05312a0439cb650d3)

I have built it by cloning both layers from git (and changing poky 
branch), then I sourced poky (source poky/oe-init-build-env), added 
meta-raspberrypi layer in conf/bblayers.conf and in conf/local.conf 
changed MACHINE to raspberrypi3.

Then I have built "rpi-hwup-image" using bitbake and dd'd it to an SD card.

Unfortunately rpi-hwup-image does not work on raspberry pi 3.
Boot screen halts when 4 raspberry logos show up and that's it.

On the other hand I have tried the same SD card with raspberry pi 2 and 
it booted up (!?).

Can you tell me if there is still support for meta-raspberrypi layer?
I found that this layer does not follow Yocto project naming convention 
for branches (I think that the latest is "jethro", but nothing newer 
besides "master").
Does this mean that there is no stable and up-to-date branch apart from 
master?

Has anybody built a raspberrypi3 image?
Could you tell me which layers and which branches should I use?


Thanks,
Piotr Lewicki

set

ENABLE_UART = "1"

in local.conf

I just tested the same revisions as you mentioned and the board boot for
me. How do you test the board? Over serial?

If you are using serial I suspecte you are not setting the serial
console. if you are using tty1 (hdmi) you need to add the specific
console argument to cmdline.

What do you mean rpi is not following the yocto project naming
convention? It does miss a branch for the last yocto release but there
are already for the old ones.

I'm using hdmi. Where can I find those console arguments?

Maybe I explained that wrong, but I've noticed that it's missing krogoth 
branch.
I think that if something like this occurs users are a little bit 
confused and have to choose between old branch (potentially outdated) 
and a master branch (potentially unstable).

Boot partition, cmdline.txt.

Correct. I'll release krogoth too soon. Thanks.

I would suggest to delay branching until we really diverge from krogoth in incompatible ways
just makes it easier to maintain.

Indeed. Sounds like a good idea.
