Problem of LCD Raster when use O-3 optimization

Hi,
I've modified the optimization and not able see any neither flickering nor fault position.
Could you please tell me which optimization used and how you enabled L1/L2 cache.
Also, please try to do the same for linked libraries project (ex: drivers,platform etc.,)

i use O-3 optimization.
CacheEnable(L1PCFG_L1PMODE_32K | L1DCFG_L1DMODE_32K | L2CFG_L2MODE_256K);

g_ptSysconfig0Reg->MSTPRI[2] &= 0x0fffffff;
g_ptSysconfig0Reg->MSTPRI[2] |= 0x10000000;

g_ptLcdcReg->RASTER_CTRL &= 0xfffffffe
g_ptLcdcReg->LCD_STAT = 0x000003ff; // Clear
// g_ptLcdcReg->LCD_CTRL = 0x00001601; //
// g_ptLcdcReg->LCD_CTRL = 0x00000a01; //
g_ptLcdcReg->LCD_CTRL = 0x00000c01; //

// g_ptLcdcReg->RASTER_TIMING_0 = ((43)<<24)+((8)<<16)+((5)<<10)+(29<<4);
// g_ptLcdcReg->RASTER_TIMING_1 = ((12)<<24)+((4)<<16)+((10)<<10)+0x10f;/*800*480*/
// g_ptLcdcReg->RASTER_TIMING_0 = ((43)<<24)+((8)<<16)+((5)<<10)+(49<<4);
// g_ptLcdcReg->RASTER_TIMING_1 = ((12)<<24)+((4)<<16)+((10)<<10)+0x1df;
g_ptLcdcReg->RASTER_TIMING_0 = ((43)<<24)+((8)<<16)+((5)<<10)+(39<<4);
g_ptLcdcReg->RASTER_TIMING_1 = ((12)<<24)+((4)<<16)+((10)<<10)+0x1df;

g_ptLcdcReg->RASTER_TIMING_2 = 0x03000000;
g_ptLcdcReg->RASTER_SUBPANEL = 0x0;
g_ptLcdcReg->LCDDMA_CTRL = 0x00000540;//0x00000020; //先传低位
// g_ptLcdcReg->LCDDMA_FB0_BASE = FRAMEBUF_BASE+0;//FRAMEBUF_BASE;
g_ptLcdcReg->LCDDMA_FB0_BASE = FRAMEBUF_BASE;//(unsigned int)&lcdimage[0
// g_ptLcdcReg->LCDDMA_FB0_CEILING = FRAMEBUF_BASE+32+480*272*2-2;
// g_ptLcdcReg->LCDDMA_FB0_CEILING = FRAMEBUF_BASE+32+CN_LCD_SIZE_X*CN_LCD_SIZE_y*2-2;
// g_ptLcdcReg->LCDDMA_FB0_CEILING = FRAMEBUF_BASE+32+800*480*2-2; //
g_ptLcdcReg->LCDDMA_FB0_CEILING = FRAMEBUF_BASE+32+640*480*2-2; //
g_ptLcdcReg->RASTER_CTRL = 0x00000080;//0x00000080;
g_ptLcdcReg->RASTER_CTRL |= 0x00000001; // Enable controller


lcd_point = (unsigned short *)0xC1A00020;//ddr
then i use the lcd_point to update the data of lcd.

Hi,
Are you using LCDK board or custom board ?
Have you modified the code ?
Could provide the screen shot of the optimization settings.

I've tried the raster LCD code on my OMAPL138LCDK (DSP core) with -o3 optimization and working good.

i use my own boad of TMS320C6748. off course i change the code of lcd raster setting

the lcd data points to ddr2 in a certain addr, i update the data every time. 

here are the optimization setting.

here is my cmd file of memory

MEMORY
{
L2: o = 0x00800000 l = 0x00040000
// share: o = 0x80000000 l = 0x00020000
L1P: o = 0x00E00000 l = 0x00008000
L1D: o = 0x00F00000 l = 0x00008000
dsp_ddrii: o = 0xc2000000 l = 0x1000000
}

Hi,
Do you have LCDK board with you ?
Have you tried the unmodified example code on LCDK board ?
Have you modified the raster example code ?

i don't have lcdk board. actually, the code is almost the same as example. only if i use optimization , the problem will appear, other parts work well . I think it maybe the ddr setting.

if i use cacheenable L2 and cacheenableMAR, the lcd will work well in debug ,but not in nor flash.
