Subject: [U-Boot-Users] LCD (NL6448BC20) on PXA255
Date: Wed, 16 Feb 2005 23:24:49 +0100	[thread overview]
Message-ID: <cv0h28$beh$1@sea.gmane.org> (raw)

Hello All,

I'm working on an pxa255 based board and I am trying to get the LCD 
started (NEC NL6448BC20-08).
The test patern is displayed perfectly.
But when I place text, the screen starts to scroll/move/shake.
What am I doing wrong? Perhaps something wrong with the settings?
But then why isn't the test patern shaking?

I added this to pxafb.c:

#ifdef CONFIG_NEC_NL6448BC20
# define REG_LCCR0	0x003008F8
# define REG_LCCR3	0x0370FF01

vidinfo_t panel_info = {
	vl_col:		640,
	vl_row:		480,
	vl_width:	132,
	vl_height:	99,
	vl_clkp:	CFG_HIGH,
	vl_oep:		CFG_HIGH,
	vl_hsp:		CFG_LOW,
	vl_vsp:		CFG_LOW,
	vl_dp:		CFG_HIGH,
	vl_bpix:	3,
	vl_lbw:		0,
	vl_splt:	0,
	vl_clor:	1,
	vl_tft:		1,
	//horizontal
	vl_hpw:		63,
	vl_blw:		48,
	vl_elw:		16,
	//vertical
	vl_vpw:		2,
	vl_bfw:		31,
	vl_efw:		12,
};
#endif

Thanks,
Wim
