Hi,
seems that framebuffer on OSK from recent git has some more
trouble (not only the missing parameter from my last mail):
It crashes completely on OSK. Backlight of LCD is enabled,
but then: See log below (low level debugging enabled,
without no messages).
Any ideas?
Best regards
Dirk

Yes, I forgot to test the fbconsole on OMAP1, now I bumped into this on
1510 as well. Your's is probably the same bug:
