Full u-boot serial output and boot log follow below. uname -a prints: Linux beaglebone 3.14.16 #1 Thu Aug 14 18:00:21 CEST 2014 armv7l GNU/Linux (the kernel was built by the linux-ti-staging recipe) The u-boot problem bootfile is set to uImage, and mmcboot uses bootm instead of bootz. Furthermore, once I correct these two values, it boots, but I see this eventually: Error opening /dev/fb0: No such file or directory After a bit of investigation, it turned out that omaplfb wasn't loading due to missing symbols: root@beaglebone:~# modprobe omaplfb [ 83.010309] omaplfb: Unknown symbol register_vsync_cb (err 0) [ 83.016642] omaplfb: Unknown symbol unregister_vsync_cb (err 0) Searching for this, I found https://groups.google.com/forum/#!topic/beagleboard/dcLtpK7ZsX0 . According to this, in the kernel log, I should set CONFIG_FB_DA8XX to "y". Is this still correct for linux-ti-staging 3.14.16 ?

Hello,

after building a rootfs for the Beaglebone Black, I see the
following files in the deploy folder for the machine:

MLO
u-boot.img
u-boot-spl.bin
zImage

as well as other symlinks with "-beaglebone" attached to their filenames.

What should I copy, the SPL bin, or the .img u-boot binary?
Also, u-boot tries to load a uImage, even though a zImage was built.
There is also no uEnv.txt file.
Do I have to write one to be able to let u-boot load the zImage, or
should it work out-of-the-box?

Depends on the rootfs image you are building. Most images that are based
on
core-image-base will take care of deploying necessary pieces into the
rootfs. But core-image-minimal is special and very bare-bone, so extra
manual steps are required.

Regardless of the rootfs image, you'd need MLO and u-boot.img to be
located in the first FAT partition of your SD card or eMMC flash.

Then, if your rootfs does not already have zImage and the necessary DTB
files in the /boot directory, you have to place them there (i.e.
core-image-minimal) and you are ready to boot. All the defaults will work
for out-of-the-box in this case. No uEnv.txt is necessary, unless you
need to do something extra special...

Oh, I just built core-image-base .

So I should use the .img and not the SPL .bin? I was wondering if the
SPL bin is a newer binary that will eventually replace the .img one.

But when I use the .img file, it turns out that it tries to load a
uImage, even though a zImage was built. Simply setting the bootfile env
var to "zImage" won't work, because the u-boot script will try to boot
with the incorrect command.

Try setting bootfile=zImage in uEnv.txt in the first partition.


I am trying to rule out that something went wrong in my build, that
something is wrong in my setup. If I build core-image-base , the
resulting u-boot.img should automatically load a zImage, not a uImage,
correct?

Can you post serial output from uboot?

Your default environment should look similar to what is here:
http://git.denx.de/?p=u-boot.git;a=blob;f=include/configs/am335x_evm.h;h=a48b386477167010c8e0d206423a3bdbe611cf83;hb=524123a70761110c5cf3ccc5f52f6d4da071b959#l78

I rebuilt the image, with the proper layers, but still I get an incorrect u-boot environment. Full u-boot serial output and boot log follow below.
uname -a prints:  Linux beaglebone 3.14.16 #1 Thu Aug 14 18:00:21 CEST 2014 armv7l GNU/Linux
(the kernel was built by the linux-ti-staging recipe)

The u-boot problem bootfile is set to uImage, and mmcboot uses bootm instead of bootz.

Furthermore, once I correct these two values, it boots, but I see this eventually:

  Error opening /dev/fb0: No such file or directory

After a bit of investigation, it turned out that omaplfb wasn't loading due to missing symbols:

  root@beaglebone:~# modprobe omaplfb
  [   83.010309] omaplfb: Unknown symbol register_vsync_cb (err 0)
  [   83.016642] omaplfb: Unknown symbol unregister_vsync_cb (err 0)

Searching for this, I found https://groups.google.com/forum/#!topic/beagleboard/dcLtpK7ZsX0 . According to this, in the kernel log, I should set CONFIG_FB_DA8XX to "y". Is this still correct for linux-ti-staging 3.14.16 ?

All layers are in their daisy branches.
