In my custom audio cape device tree fragment the modes are setup like thus.
pinctrl-single,pins =

Hi,
I built linux-omap-psp-2.6.37 kernel for BB xM with version
uImage--2.6.37-r125b.2. But I stops at
Uncompressing Linux... done, booting the kernel.
I have console=ttyO2,115200n8, I tried to change kernel configuration, but
I can not figure out.
Thanks!
Kai

Of course! Because changing u-boot environment variables means nothing for

I was wondering why there wasn't much activity recently! I was looking at
the 3.8 branch and noticed that Robert had added SGX... it would appear
that 3.8 will also now have SGX working, not only 3.14, right? I didn't

Ok, so rather coming in and sniping a comment Jjohn, why dont you try and
set an optargs env variable in the initial uEnv.txt file and see what
happens.
If you're using the same uboot we're using, it wont work. Now, feel free to
find yourself trolling a different post.

Hi again,
I just tried wrapping my optarg in quotes and it didn't make a lick of
difference, so that's not it.
It's seems that I should have the latest uboot since I'm running an image
from 3 days ago.
My optargs aren't broken.

Since both of you seem convinced that optargs is not broken, why dont you
actually go make changes to your own uEnv.txt and test if what you think
will work, actually works. What I did works, as I tested it myself.

Jason, odd, it seems to be working for me now too. Previously the cmdline
env variable was overriding my optargs statements.

Once again --- thanks, folks. It's always useful to have some trail

I don't know if capemanager is functional for these new fangled kernels.

something else that was broken?
But if you can make it work why isn't it working
Jason, hah ! I see why now. Can you see the problem ?
*uname_r=3.15.10-bone8*
*cmdline=quiet init=/lib/systemd/systemd*
*optargs=consoleblank=0*.
This is actually in the wrong file. For this to work in the file he's using
there it needs to be as i said above. Which is:
*cmdline=quiet
This should be that $optargs works in the initial uEnv.txt file loaded at
boot, but not the second stage uEnv.txt file which is pulled in by the
stage 1 file.
False alarm ( again ).
