I'm on master branch trying to build core-image-minimal for the machine "pandaboard". Besides the basics, I put in a license statement for cloud9 into local.conf.

My bblayer.conf is as follows:

# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly

Try adding this in local.conf:
BBMASK ?= ".*/meta-ti/recipes-(misc|bsp/formfactor)/"
BBMASK by itself didn't solve my particular problem. I'll try the other suggestions and report back.
What other problem do you have? That BBMASK should keep bitbake from
trying to parse the recipe mentioned above.

Note: I use these layers with Yocto all the time with that mask...
When I just used the statement:

BBMASK ?= ".*/meta-ti/recipes-(misc|bsp/formfactor)/"

I got the same error as my original post.
The only way you could get that same error is if you already have a BBMASK
statement somewhere and this one is being ignored because of the ?= assignment.
So I started with a clean build again. This time I only added the BBMASK statement you suggested. I got the following error:

ERROR: No recipes available for:
ERROR: Command execution failed: Exited with 1

I'm guessing the BBMASK needs to call out meta-openembedded/meta-systemd/meta-gnome and meta-efl?
Or don't include those layers - meta-systemd isn't needed by your yocto build.
Thanks, that makes more sense now. I removed the layer meta-systemd from bblayers.conf and used the

BBMASK ?= ".*/meta-ti/recipes-(misc|bsp/formfactor)/"

statement in local.conf to solves the problem.

What is really causing the problem? Without it dependencies on meta-systemd are there, but the mask removes that?? Why can you remove a dependency?
The dependency on systemd comes from this recipe: meta-ti/recipes-misc/payload/
The BBMASK is making bitbake ignore that recipe (you don't need it), hence no dependency.
I got core-image-minimal built without errors, Thanks, now I need to ask some questions about booting that image. I'm assuming that I can follow the instructions on
for creating the SD card format and just copy the deploy/image/ u-boot, MLO, uImage, and rootfs to the right places and boot the sdcard in the pandaboard. Anyway, that's what I
tried. I'm connected to the panadboard via serial port and the U-Boot works and the uImage seems to be found, but I don't get a login console on the serial port:

Start with the obvious - check the bootparams in U-Boot. Break into
the boot process and run the 'printenv' command. What's the value of
the "console" variable?

n.b. I've not tried this exact setup on the PandaBoard. I may have time
later today to do so.
I've just verified that this does fail when using yocto:master I'm pretty
sure that the problem is related to the use of GCC 4.7.1 - I've had similar
problems with ARM kernels & GCC 4.7.1 in the past.

I did build yocto:denzil for the PandaBoard and it comes up and mostly works.
I've not done extensive checking on this image though.
This problem that I have on denzil with pandaboard is I get the following error:

ERROR: ParseError at /home/jim/meta-openembedded/meta-oe/recipes-navigation/gpsd/ Could not inherit file classes/pythonnative.bbclass

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

I already have a BBMASK statement in local.conf:

BBMASK ?= ".*/meta-ti/recipes-(misc|bsp/formfactor)/"

I'm not sure how I add a second statement like:

BBMASK ?= ".*/meta-openembedded/meta-oe//recipes-navigation/"

Do I use += in both or what???
