[U-Boot-Users] LCD on pxa255

[himba <himba@siol.net>]

Hi,

I'm trying to hook up passive LCD to pxa255, so I defined my LCD type 
and CONFIG_LCD in config and created vidinfo_t struct in 
cpu/pxa/pxafb.c. I compiled and burned it to flash. After reboot I get:
U-Boot 1.0.2 (Jun  8 2004 - 23:06:10)

U-Boot code: A3F00000 -> A3F18530  BSS: -> A3F1BFB4
RAM Configuration:
Bank #0: a0000000 64 MB
Bank #1: a4000000  0 kB
Bank #2: a8000000  0 kB
Bank #3: ac000000  0 kB
Flash: 32 MB

-- hang ?! --
No logo appears and no test pattern is visible (LCD is powered on and 
blanked/or with some horizontal lines drawn).

Has anybody successfuly connected passive LCD to  pxa ?
