SDP support seems broken in LO

SDP support seems broken in LO

[vimal singh]

LO seems broken on OMAP3430 SDP platform. I compile latest kernel with
'omap_3430sdp_defconfig' config options.

Booting hangs after kernel uncompressed and last message which appears
is 'booting the kernel'


Thanks and regards,
vimal

See below log:

Mainly because of frame-buffer and musb. You can try disabling these two and see if it boots.

I disabled frame-buffer and usb support fully:
# CONFIG_FB is not set
# CONFIG_USB_SUPPORT is not set

I still get same message.

Do you have CONFIG_DEBUG_LL enabled? If so, could you enable that please to
see if we have a crash somewhere?

And here's the problem - you're using CodeSourcery's 2007q3 toolchain.
This has been discussed in the past on this list. I don't know exactly
what causes the problem or what fixes this.

Move to 2008q3 or 2009q1 as a workaround.
