Problems building Yocto for iMX28EVK

[Flavio Castro Alves Filho]

Hello,

I'm trying to build Yocto Project (Poky) for imx28evk.

Here are the steps that I followed:

mkdir ~/yocto

cd ~/yocto

git clone git://git.yoctoproject.org/poky

cd poky

git clone git://git.openembedded.org/meta-openembedded

git clone git://git://github.com/Freescale/meta-fsl-arm.git

cd ..

source poky/oe-init-build-env imx28evk-linux

Then I changed conf/bblayers to include meta-openembedded/meta-oe and meta-fsl-arm layers. And, I added the MACHINE ?= "imx28evk" instruction.

When I execute 'bitbake core-image-minimal' I have the following error:

bitbake core-image-minimal

Pseudo is not present but is required, building this first before the main build

When I search for the original file (qt4-embedded_4.7.4.bb), I could not find this file. I can find the file qt4-embedded_4.8.1.bb. I believe that the qt library has been updated.

I would like to ask which is the correct setup for meta-fsl-arm in order to build correctly the imx28evk project. Should I use an older version of Yocto?

Thank you in advance.

Best regards,

Flavio

Here you should checkout the denzil branch.

I think this would fix your build problem.

As Fabio told you, we do not yet support Yocto's master branch but
denzil; please checkout denzil branches for OE/Poky and meta-oe and it
will work fine.

Aha, I see many place has a "denzil" branch, what is this branch for?
and why it call this name?
all the things related yocto need to use this branch?

I believe it is the Poky's version name.

1.2 release of Yocto

This is the release codename.

Yes; for a working set of branches.

As Fabio told you, we do not yet support Yocto's master branch but
denzil; please checkout denzil branches for OE/Poky and meta-oe and it
will work fine.

I was previously trying to build with OpenEmbedded-Core for imx28evk, but without success. Now I try Yocto. I did the following:

mkdir -p ~/oe-core/freescale-arm
cd       ~/oe-core/freescale-arm
git clone git://git.yoctoproject.org/poky -b denzil
git clone git://git.openembedded.org/meta-openembedded -b denzil
git clone git://git://github.com/Freescale/meta-fsl-arm.git -b denzil
cd poky

Then I edit in conf/bblayers.conf:

BBLAYERS ?= " \
  /home/craigm/oe-core/freescale-arm/poky/meta \
  /home/craigm/oe-core/freescale-arm/poky/meta-yocto \
  /home/craigm/oe-core/freescale-arm/meta-openembedded/meta-oe \
  /home/craigm/oe-core/freescale-arm/meta-fsl-arm \
  "

Then I edit conf/local.conf:

...
BB_NUMBER_THREADS = "4"
...
PARALLEL_MAKE = "-j 4"
...
MACHINE ?= "imx28evk"
...
DL_DIR ?= "/home/craigm/oe-downloads"

I set DL_DIR as shown, because I didn't want to re-download everything again, but rather reuse the downloads from my previous OpenEmbedded-Core attempts. I moved the download directory from one of my previous OpenEmbedded-Core attempts to /home/craigm/oe-downloads.

Then set up for a build:

source oe-init-build-env

Then build:

bitbake core-image-minimal

Build succeeded. Then write to 4 GB SD card (~30 mins):

sudo dd if=tmp/deploy/images/core-image-minimal-imx28evk.sdcard of=/dev/sdc

Then boot in the board with the SD card in SD slot 0. But it doesn't work. It gets as far as "Uncompressing Linux... done, booting the kernel", but no further. Am I missing something?

Go to the U-boot prompt, and check the "console" variable. It should
be console=ttyAMA0, instead of ttyAM0.

[cmcqueen1975]

Thanks for the tip. I had checked that, and saw there was:

console=${console_mainline}
console_fsl=ttyAM0
console_mainline=ttyAMA0

 So that looked fine to me. But, I decided to try changing it anyway:

setenv console ttyAMA0
saveenv

Then booted again, and this time it got further through the boot process (though not all the way to a login prompt). So the line console=${console_mainline} isn't being evaluated as I'd expect.

If I understand correctly, that initial U-Boot configuration is what is written to the SD card from the Yocto + meta-fsl-arm build process. Is that right, or is it coming from somewhere else?

[Otavio Salvador]

Yes; this is the initial ...

I will check what is broken on this as it ought to work out of box.

Hello,

2012/9/3 cmcqueen1975 <google...@craig.mcqueen.id.au>

I'm not a git expert, but I perform a different approach here:

git clone git://git.yoctoproject.org/poky

cd poky

git checkout -b local/origin/denzil remotes/origin/denzil

cd ..

git clone git://git.openembedded.org/meta-openembedded

cd meta-openembedded

git checkout -b local/origin/denzil remotes/origin/denzil

cd ..

git clone git://git://github.com/Freescale/meta-fsl-arm.git

cd meta-fsl-arm

git checkout -b local/origin/denzil remotes/origin/denzil

cd ..

And continue your procedure. At least for me it is working very well ... and I could deploy correctly the image from sdcard.

 

Then I edit in conf/bblayers.conf:

BBLAYERS ?= " \
  /home/craigm/oe-core/freescale-arm/poky/meta \
  /home/craigm/oe-core/freescale-arm/poky/meta-yocto \
  /home/craigm/oe-core/freescale-arm/meta-openembedded/meta-oe \
  /home/craigm/oe-core/freescale-arm/meta-fsl-arm \
  "

Then I edit conf/local.conf:

...
BB_NUMBER_THREADS = "4"
...
PARALLEL_MAKE = "-j 4"
...
MACHINE ?= "imx28evk"
...
DL_DIR ?= "/home/craigm/oe-downloads"

Well both are correct.

When you specify the -b <branch> in clone, instead of doing the checkout of master it default to checkout the branch you requested so it reduces the number of steps you have to do for setup your tree. By default, except if using a shallow clone (--depth argument) or --single-branch argument, you will have whole history of all branches anyway.

For initial use I think our fsl-community-bsp makes life easier but it is a personal choice.
