[meta-atmel] at91sam9x5ek: "no machine record defined" failure for core-image-minimal

Hi,

Not sure if this is the correct place to email this, but I've seen a few other meta-atmel references so I figured I'd give it a shot.

I'm attempting to setup a core-image-minimal build using the guidelines in the meta-atmel README for the at91sam9x5ek machine type. When the kernel build goes to link, I get a "no machine record defined" error. Is this something others are seeing in the meta-atmel demo builds?

It's a pretty benign build setup according to the README:

git clone git://git.yoctoproject.org/poky
cd poky
git checkout dora-10.0.1 -b dora-10.0.1
git clone git://git.openembedded.org/meta-openembedded
cd meta-openembedded
git checkout 6572316557e742c2dc93848e4d560242bf0c3995 -b my_branch
cd ..
git clone http://github.com/linux4sam/meta-atmel
source oe-init-build-env /workspace/build-atmel

modify local.conf:

MACHINE ??= "at91sam9x5ek"

PACKAGE_CLASSES ?= "package_ipk"

modify bblayers.conf:

BBLAYERS ?= " \

  /opt/poky/meta-atmel \

  /opt/poky/meta \

  /opt/poky/meta-yocto-bsp \

  /opt/poky/meta-openembedded/meta-oe \

  /opt/poky/meta-openembedded/meta-networking \

  "
bitbake core-image-minimal

Setting this up, I get the following build configuration and error:

Any thoughts on what might be missing from the README or my implementation of it to get this demo build working?

Can you confirm that the final .config for the board has the machine
definitions that you'd expect for the board ?

Re: [meta-atmel] at91sam9x5ek: "no machine record defined" failure for core-image-minimal

[Brian Karcz]

Hi Bruce,

I'm not entirely familiar with the mechanism that gets the defconfig from the BSP to the .config in work area, but here is how things currently look. The two files aren't a direct match as there appear to be some formatting differences, but the variables in the SOC/ARCH section seem to correlate partially (ie. it knows its trying to build for an at91sam9x5 SOC).

defconfig:
	CONFIG_ARCH_AT91=y
	CONFIG_SOC_AT91SAM9260=y
	CONFIG_SOC_AT91SAM9263=y
	CONFIG_SOC_AT91SAM9G45=y
	CONFIG_SOC_AT91SAM9X5=y
	CONFIG_MACH_AT91SAM_DT=y

.config:
	#
	# Atmel AT91 Processor
	#
	# CONFIG_SOC_AT91RM9200 is not set
	CONFIG_SOC_AT91SAM9260=y
	# CONFIG_SOC_AT91SAM9261 is not set
	CONFIG_SOC_AT91SAM9263=y
	# CONFIG_SOC_AT91SAM9RL is not set
	CONFIG_SOC_AT91SAM9G45=y
	CONFIG_SOC_AT91SAM9X5=y
	# CONFIG_SOC_AT91SAM9N12 is not set

	#
	# Atmel Non-DT world
	#
	CONFIG_ARCH_AT91_NONE=y
	# CONFIG_ARCH_AT91RM9200 is not set
	# CONFIG_ARCH_AT91SAM9260 is not set
	# CONFIG_ARCH_AT91SAM9261 is not set
	# CONFIG_ARCH_AT91SAM9263 is not set
	# CONFIG_ARCH_AT91SAM9RL is not set
	# CONFIG_ARCH_AT91SAM9G45 is not set

	#
	# AT91 Board Options
	#

	#
	# Generic Board Type
	#
	# CONFIG_MACH_AT91SAM9_DT is not set

Given the fact that the ARCH and DT variables don't appear to match, it looks like this might be device tree related.

I was hoping the code out of the box was going to be able to provide a demo image that I could build and poke around in for some guidance. My ultimate goal is to port the at91sam9x5ek machine definition to one for the at91sam9g20ek demo board and then port THAT over to a custom machine based roughly off that reference design.

The reason I asked is that in the past, the error you are seeing
was related to the machine not being properly defined in the
kernel's .config.

FWIW, assuming you have a full "defconfig", and not a "save_defconfig"
variant, the path from it to the final .config is pretty much a copy
into the kernel and a "make oldconfig", so nothing is thrown away
unless there is a missing dependency, or the Kconfig doesn't exist in
the given kernel.

It's worth checking via menuconfig to see if anything obvious is
missing, and trying some quick builds to rule out a bad configuration.

My ultimate goal is to port the at91sam9x5ek machine definition to one for the at91sam9g20ek demo board and then port THAT over to a custom machine based roughly off that reference design.

I'm currently using a fork of the meta-atmel layer for my at91sam9g25 board.  If I remember when they added at91sam9x5 support for meta-atmel, I think the layer was on kernel 3.6.9 and now it's on 3.10.  There's been a lot of machine and device tree related configuration changes for this chipset between 3.6.9 and 3.10, so that configuration might not work for 3.10.

The configuration I'm currently using is over at https://github.com/evensonbryan/meta-atmel/tree/master/recipes-kernel/linux/files/at91sam9x5ek/linux-3.10-at91.  It also has some patches I added in to pick up some missing peripheral support for my system.  You may want to give that a try and see if it helps.

Regards,
Bryan

Re: [meta-atmel] at91sam9x5ek: "no machine record defined" failure for core-image-minimal

[Brian Karcz]

Hi Bruce,

Yeah, that's the avenue I'm going to have to go down. I was hoping to avoid the trial by fire approach and learn by making small mods to an existing working build, but it looks like that might not be in the cards. I was hoping that one of the at91/linux4sam people or someone familiar with meta-atmel might be lurking in here and have seen the same issue when following the instructions in the layer's README file and have a "oh yeah, just tweak this..." fix.

I'll have to take a look through some of the linux-yocto-custom log files to see where the .config is getting generated from and whether the defconfig from the BSP kernel recipe is playing a roll in it. I'm guessing without an explicit board file (which there isn't) and the CONFIG_MACH_AT91SAM9_DT parameter not making its way from defconfig to the .config, that would explain why there is no machine record macro being declared.

I'll keep digging...

Thanks,
Brian

The reason I asked is that in the past, the error you are seeing was related to the machine not being properly defined in the kernel's .config.

FWIW, assuming you have a full "defconfig", and not a "save_defconfig"
variant, the path from it to the final .config is pretty much a copy into the kernel and a "make oldconfig", so nothing is thrown away unless there is a missing dependency, or the Kconfig doesn't exist in the given kernel.

It's worth checking via menuconfig to see if anything obvious is missing, and trying some quick builds to rule out a bad configuration.

Hi Bryan,

Thanks for the tip. Any chance you tried assigning the PREFFERED_VERSION to 3.6.9 and using the linux4sam meta-atmel layer as is?

I'll definitely check out your layer. I was hoping the at91sam9x5ek would just build so that I could start tweaking it to define a machine works for its little brother, the at91sam9g20ek.

I'm coming from an older 2.6.30 kernel that used a board file instead of the device tree and was planning to use the demo build from meta-atmel and some small mods to give myself a crash course on device tree development. Looks like the learning curve might have steepened a bit.

Thanks,
Brian

Brian,

I'm currently using a fork of the meta-atmel layer for my at91sam9g25 board.  If I remember when they added at91sam9x5 support for meta-atmel, I think the layer was on kernel 3.6.9 and now it's on 3.10.  There's been a lot of machine and device tree related configuration changes for this chipset between 3.6.9 and 3.10, so that configuration might not work for 3.10.

The configuration I'm currently using is over at https://github.com/evensonbryan/meta-atmel/tree/master/recipes-kernel/linux/files/at91sam9x5ek/linux-3.10-at91.  It also has some patches I added in to pick up some missing peripheral support for my system.  You may want to give that a try and see if it helps.

Regards,
Bryan

I would take a look at using at least the 3.10 kernel from Atmel.  It's the most stable one they have and it's where they've been backporting additional device tree support.  I believe if you use my defconfig, you should be able to build a 3.10 kernel with Atmel's latest layer.  And definitely start reading up on device tree development.  It takes some getting used to but it is a good step forward.

Bryan
