Hi Tony,
We are using the panda board (es variant) for testing our SDIO based chips. For
this we have an adapter card connection to expansion connector A. As this
adapter is not publicly available we had internally patched board-omap4panda.c.
Also we follow the -rc releases and use TFTP to boot the kernel image which
requires USB.
Moving to 3.11-rc1 I found that the mentioned board file was removed by your
commit:
commit b42b918194c4791510ac049e3d507169a7de8544

ARM: OMAP2+: Remove board-omap4panda.c
As our patches on that file are internal I do not hold it against you. This is
no regression and we need to fix it.
So my first step was to follow the recipe given in that commit. Beside that I
noticed a thread about USB issue on LKML so I also applied the following commit:
commit 352f573e59050c7a604c35c58b4bbfc51edebbee

ARM: OMAP2+: Provide alias to USB PHY clock
The attached kernel log seems to suggest that the device tree is picked up by
the kernel, but the USB does not seem very active. No ethernet connectivity.
This does seem a regression to me. Is there some other patch that I need to get
it going again?
I tried with your config and 3.11-rc1 kernel with the above commit on top and
ethernet seems to
work for me. My boot log is attached.
Are you sure that you are building the DTB for panda-es and the bootloader is
picking up the right file and
not an outdated one?
I appended the DTB to the kernel image thus avoiding the need to update
u-boot (at least that is what I understood from Tony's commit).
Why is the version of SPL loader and u-boot different in your log?
You need to use the MLO file generated by the u-boot build along with the
uImage.
Just to be sure we are on the same setup could you please try with latest
u-boot release (2013-04). Thanks.
I recall having difficulty with TFTP boot using a 2013 u-boot release,
but that hurdle is for later. I will try.
cheers,

Thanks,
Arend
