* Update BeagleBone to 3.8.13-beagleboard kernel
* Update to u-boot 2013.07
* Add BeagleBone Black device tree
* Remove M3 firmware loading until debugged
* Remove BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_DEVTMPFS because it is the default

Just to make sure this is documented well, here are the steps I used to test
the output images:
 # gzip rootfs.ext2
 # mkimage -A arm -O linux -T ramdisk -C gzip -a 0x81000000 -d rootfs.ext2.gz ramdisk.gz
 # The URL is where I stored the ouptut of 'make beaglebone_defconfig; make'
 $ wget -r https://s3.amazonaws.com/beagle/buildroot/2013-10-11-16%3A52%3A21/index.html
 $ cd s3.amazonaws.com/beagle/buildroot/2013-10-11-16:52:21
 $ cat >uEnv.txt <<EOF
 bootpart=0:1
 bootdir=
 uenvcmd=run loaduimage;run loadramdisk;run findfdt;run loadfdt;run ramboot
 EOF
 # With /mnt being a FAT formatted uSD card with partition marked as bootable
 $ cp MLO u-boot.img uImage ramdisk.gz uEnv.txt *.dtb /mnt
 # eject /mnt
 # Insert uSD card into BeagleBone Black
 # Hold "BOOT" button
 # Apply power and release "BOOT" button
 # Serial log at screenlog.0

Ideally for me, I'd switch to an initramfs and patch u-boot to avoid uEnv.txt,
but I'll do that separately.

Changes since v2 (http://lists.busybox.net/pipermail/buildroot/2013-September/079136.html):
* Moved back to ext2/ramdisk and eliminated u-boot customizations
* Removed host tool customizations

Changes since v1 (http://lists.busybox.net/pipermail/buildroot/2013-September/079046.html):
* Added BeagleBone Black to single config for BeagleBone and BeagleBone Black,
  rather than having two configs
* Used 'make ARCH=arm savedefconfig' to create Linux config file
* Dropped setting of DEVTMPFS, since it is default now
* Switched to u-boot 2013.07 from 2013.04
* Patched u-boot to work with initramfs by default without uEnv.txt
* Removed wake-up M3 firmware loading for now, until debugged

Hello Jason,
Thanks for contributing to Buildroot for Beaglebone.

One quick question as the device tree stuff is new to me. Do I need to
manually put the correct dtb file for BBB and BB_white respectively on
/uSD/boot/*.dtb or does the system have a way to pick the correct dtb file
for each platform during boot time?

To restate, I cant just put both am335x-bone.dtb & am335x-boneblack.dtb on
/boot can I?

I am trying to get my old BB white cape working on BBB and will need to
familiarize myself with the device tree ASAP!

Thanks again,
-Jesse

All this logic is done by the U-Boot scripts integrated in the U-Boot
environment, so you'll have to look at these scripts to see which DTB
they load at boot time. You can of course adjust these scripts to
ensure they load the right DTB.

Best regards,

Thomas

Jesse,

You'll notice in my commit notes the 'uenvcmd' with 'run findfdt'.
That has the magic to pick out which .dtb to load. If you try it out,
I hope you'll give me a "Tested-by" and help me get this finally
committed. Not sure what else is needed to get this into buildroot.

Regards,
Jason

  This kind of information should go into board/beaglebone/readme.txt.

  If you set BR2_TARGET_ROOTFS_EXT2_GZIP you don't need to do this.

  However, using ext2 for a ramdisk image is horribly inefficient. You'd 
normally use a cpio image. Also, lzma (smaller size) or lzop (larger but 
faster uncompression) are better choices than gzip.

  Ideally, you should make a post-image script 
(BR2_ROOTFS_POST_IMAGE_SCRIPT) in the board/beaglebone directory that 
does these steps automatically. And since this script uses mkimage, I'd 
also explicitly enable BR2_PACKAGE_HOST_UBOOT_TOOLS (even though it is 
implicitly build for the kernel uImage).

  You can add uEnv.txt to board/beaglebone and copy it to images/ in the 
post-image script.

  With the post-image script, the readme can be limited to these 7 lines :-)

  I'm not a fan of initramfs because every rootfs change requires a slow 
re-link of the kernel... And I don't see the harm in uEnv.txt.

  The patch changelog should be preceded by --- (on a line by itself). 
This separator tells git that what follows it doesn't have to be included 
in the commit log.

  You're adding a lot of kernel features here that were not enabled 
before. We generally prefer the kernel configs to be pretty minimal 
(except that all drivers for hardware that is present on the board should 
be included, of course. What's the history of this kernel config? You 
don't mention it at all in the commit message.

  Yeah, for USB devices you could consider that it's always possible to 
plug them in, but most of them are anyway useless without any userspace 
support... I would keep mass storage and vfat, though.

  Keeping all possible extfses makes sense, but all the rest should go 
IMHO. Perhaps NFS can stay.

  Definitely flash filesystems shouldn't be there.

  We normally don't keep things in comments, but here I think it makes 
sense to keep this package in a comment and mention that it is not 
included for the time being due to instability. That will invite a future 
version bumper to re-include it.


  Sorry for the large number of comments so long after you posted the 
patch...

I thought I had pushback on using initramfs, which is what I'd prefer
to have as the default. I'm simply trying to minimize the patch to get
Black in there in the defaults.

Thanks for pointing this out and I'll certainly make personal use of
it. I'm doubtful if including it would help get my patch accepted.

k, but again, I'm not sure if it is desired upstream. If I add it to
v4, will it get accepted?

k, but you want a cpio image instead of a ramdisk? I guess I'll take a
look at how to use a cpio image as an initrd.

What I'd like to know is what will be accepted upstream. I feel like I
am wasting my time right switching approaches that don't have that
much to do with BeagleBone Black when what I most fundamentally want
to introduce is a pointer to a different kernel and the combination of
.dtb files for BeagleBone and BeagleBone Black.

This comes from the kernel config we use in the demo image shipped
with the boards.

https://github.com/beagleboard/kernel/commits/3.8/configs/beaglebone

Should I include a link like this?

I can use something more minimal, but the idea was to try to provide
something that showed off as much capability as possible. I'll see
what I can cut out.

They have eMMC, which isn't the same as MTD, so, right, there isn't
any MTD flash built-in. However, with add-on board it is possible to
add it. Many of the things added are for being able to support add-on
boards.

Agree there are many that simply don't have the userspace support. I'll trim.

Note: I haven't included the cape firmware .dtbo files that are needed
for those. It is a good TODO to add those.

k. I'll avoid the '+' on the file systems that aren't likely to be

  Fair enough. Switching to cpio (and lzma or lzop) can be done later.

  Actually, I'm not sure what "pushback" means. Does that mean you got 
approval or opposition?

  Looking back at the earlier conversation (which I didn't really 
follow), you wrote about initramfs:

  The cpio image will achieve exactly the same, but more efficiently - 
you just need the additional mkimage step and the uEnv.txt to load it. 
Maybe that's what you really want to avoid with the initramfs?

  We're moving in the direction that the board configs should produce 
something that can be copied easily on an SD card to boot the board. So 
yes, it would help. But as mentioned before, it may help even more if 
it's in a follow-up patch.

  I think so, yes. Note that this step is only relevant if you also 
create the ramdisk image. So again, maybe better for a follow-up patch.

  It's used exactly the same. The difference is that you don't have ext2 
filesystem overhead - the cpio image is copied into a tmpfs, and then 
removed.

  Good point.

  If it's an upstream defconfig, I think it's OK as it is.

  It looks like you have commit access to the beagleboard linux tree on 
github; perhaps you can add the beaglebone defconfig to arch/arm/configs, 
where it belongs? Then you can use BR2_LINUX_KERNEL_USE_DEFCONFIG.

  I think we would prefer that approach rather than a buildroot-specific 
defconfig, because it makes bumping the kernel version easier. Peter, can 
you confirm that an upstream defconfig is preferred even if it is not 
minimal?

  If an in-kernel defconfig is not possible for whatever reason, you can 
leave the defconfig as it is and mention in the readme and/or the commit 
message where it comes from.

  Ah of course. But I guess only EEPROM is relevant then - or is the GPMC 
bus exported on the cape connector?

  Didn't notice before, but: on github you can download it as a tarball. 
That's factors faster than cloning a git repository.

I was looking forward to this being accepted in buildroot.

Jason, could you send a V4 with the trimmed kernel config? Or Peter,
could we accept this patch and make changes with follow up patches?

Kind Regards,

It's on my to-do list, but messing with the 3.12 kernel is higher
priority right now.

Thiago Correa Nov. 7, 2013, 7:30 p.m. UTC | #11

I was looking at the other mails about bbb, and there was also a patch
to enable the add on boards (capes). If we consider that patch, then
it would be better to keep this patch with the linux config as it is
right now, which supports most of the capes peripherals.

Is there anything else that is keeping this patch from being accepted?
If so, would it be ok if I make the changes in follow up patches?

Kind Regards,
     Thiago A. Correa
