beagle won't boot.

beagle won't boot.

[Rick Bronson]

Hi,

  I got the lastest code on Oct 16 via:

git clone git://source.mvista.com/git/linux-omap-2.6.git
cd linux-omap-2.6
make omap3_beagle_defconfig
make uImage CROSS_COMPILE="arm-angstrom-linux-gnueabi-" CC="ccache arm-angstrom-linux-gnueabi-gcc-4.2.1+csl-arm-2007q3-53" LD="arm-angstrom-linux-gnueabi-ld"

  and it doesn't seem to want to cooperate with my beagleboard.  As
far as I can tell, it's stuck in

the while loop in omap_start_ehc().  I think because this bit never
got set:

CM_FCLKEN3_CORE->EN_USBTLL (page 472 of the OMAP3 pdf).

  Might have something to do with "usbtll_fck".

  Any help greatly appreciated.

  Thanks,

  Rick

Quick and simple solution,
1. "make menuconfig"
2. Go to Device Drivers -> USB Support
3. Disable EHCI HCD
4. Rebuild and boot

EHCI doesn't work anyway on beagle. Why bother having it built in in defconfig?

I've disabled EHCI for now in all board configs.
