Hi,.
I think the problem is fixed. I changed this line.
ptrLine = &ptrScreen[y * m_pPrimarySurface->Stride() / 2]; to
ptrLine = &ptrScreen[y * m_pPrimarySurface->Stride()];
Now I have only single cursor.
But in all pop up message windows, the title bar color(blue) is not
uniform, kind of contrast difference is there at the end just before X
mark. Is there something wrong with the palette (syspal.h)?

I supposed to change anyother thing than cursoron and cursor off.
The mouse can traverse only half of the screen along y axis. X azis
traversing is ok but if the cursor crosses the y axis(say from left to
right) another cursor is created in the left most. So I see two
cursors.
I have changed these buffers from USHORT to UCHAR.
CURSOR_GLOBALS USHORT gCursorData[CURSOR_BYTES];
CURSOR_GLOBALS USHORT gCursorMask[CURSOR_BYTES];
USHORT m_CursorBackingStore[CURSOR_SIZE];
Should I do anything else. Help me out.

Yep. But the best solution will be to remove completely
the useless "dirty rect dump" stuff from the driver
(which is there since the days of SA1110) and use
the supported by the PXA LCD controller h/w cursor.

But I'm not able to understand those functions well.
Should I make all USHORTs in cursor functions to UCHAR ?

It looks like your cursor painting is still in 16bpp
while the rest stuff migrated to 8bpp.
80.rishi@xxxxxxxxx wrote:Thanks voidcoder.
Bpp = 3.
I think I just got it. There is a 'if' statement in DispSetPalette()
which is preventing from palette ram update. I modified that and
display looks ok now.
But Im getting new 2 new issues
1) The title bar of the popup that I get once explorer starts is
discolored. Even the text looks faded. But rest of the display and
icons are proper.
2) My mouse cursor is so big and skewed.
Advise me on these issues.

What is value of "BPP" at this point?

Mainstone II BSP. I chose display type LTM035A776C because only this
showed sth in the display earlier but with color problems. After which
I learnt my board is hardwired for 18 bpp. Went for 8 to 18 bpp lookup.
Here is the code. Have given here the code break from diff. parts.
file Dispdrv.c
---------------------
DispDrvrInitialize()
{
BPP = 8;
XllpLCD.PixelDataFormat = PDFOR_11;
}
DispDrvrSetPalette()
{
// v_pPaletteBuffer->palette[i] = unsigned long
v_pPaletteBuffer->palette[i] = (
((DWORD)(source[i].peBlue>>2) <<2 ) |
((DWORD)(source[i].peGreen >> 2) << 10) |
((DWORD)(source[i].peRed >> 2) << 18)
);
}
typedef struct
{
unsigned long palette[256];
}LCD_PALETTE;
volatile LCD_PALETTE * v_pPaletteBuffer = NULL;
v_pPaletteBuffer = (volatile LCD_PALETTE
*)(PALETTE_BUFFER_BASE_VIRTUAL);
File xllp_lcd.c

LCDInitController()
{
case BPP_8:
//pXllpLCD->PaletteSize = 512;
pXllpLCD->PaletteSize = 1024;
break;
// Configured for 640*480, pixel clock = 25 Mhz, Vsync = 65 Hz
p_LCDRegs->LCCR0 = (LCD_LDM | LCD_SFM | LCD_IUM | LCD_EFM | LCD_PAS |
LCD_QDM | LCD_BM | LCD_OUM | LCD_RDSTM | LCD_CMDIM | LCD_OUC |
LCD_LDDALT);
p_LCDRegs->LCCR1 = (LCD_PPL(0x27FU) | LCD_HSW(0x3F) | LCD_ELW(0x0F) |
LCD_BLW(0x2fU) );
p_LCDRegs->LCCR2 = (LCD_LPP(0x1df) | LCD_VSW(0x01) | LCD_EFW(0x0B) |
LCD_BFW(0x1F) );
p_LCDRegs->LCCR3 = (LCD_PCD(PCD) | LCD_BPP(BPP) |
LCD_PDFOR(pXllpLCD->PixelDataFormat));
p_LCDRegs->LCCR4 = LCD_PAL_FOR(2);
}
Requet you to help me out. I checked and DispDrvrSetPalette is getting
called.

Mainstone II, PB 5.0.
I have read all the articles to implement 8 to 18 lookup. I think I
have made the necessary changes.
When I load the image my display is pitch black and no color, no text.
Am I missing something out. How do I use the default palette given in
syspal.h. Do I have to do anything.
Thanks in advance
