TFT+LPC2478 Опции

[Microsha_59]

Попытался подключить TFT(5:6:5; 320x240) модель MTF-TQ57SN721-AV к LPC2478. В итоге дисплей запустился, но корректно заработала только часть экрана начиная с 127 по 240 строку, а до 127 строки выводит не то, что надо.
Кто-нибудь знает из-за чего это может быть.

Вот текст инициализации дисплея:

#define BUFFER_ADDR 0xA0000000
unsigned short * Ptr;

void InitPanel(void)
{
DWORD i;

PCONP |= 1<<20;
PINSEL11 = ( (5<<1) | 1);

PINSEL4 &= ~(3<<4);
PINSEL4 &= ~(3<<6);
PINSEL4 &= ~(3<<8);
PINSEL4 &= ~(3<<10);
PINSEL4 |= ((3<<4) | (3<<6) | (3<<8) | (3<<10));

PINSEL3 &= ~(3<<8);
PINSEL3 &= ~(3<<10);
PINSEL3 &= ~(3<<12);
PINSEL3 &= ~(3<<14);
PINSEL3 &= ~(3<<16);
PINSEL3 &= ~(3<<18);
PINSEL3 &= ~(3<<20);
PINSEL3 &= ~(3<<22);
PINSEL3 &= ~(3<<24);
PINSEL3 &= ~(3<<26);
PINSEL3 |= ( (1<<8) | (1<<10) | (1<<12) | (1<<14) | (1<<16) | (1<<18) | (1<<20) | (1<<22) | (1<<24) | (1<<26) );

PINSEL4 &= ~(3<<12);
PINSEL4 &= ~(3<<14);
PINSEL4 &= ~(3<<16);
PINSEL4 &= ~(3<<18);
PINSEL4 &= ~(3<<24);
PINSEL4 &= ~(3<<26);
PINSEL4 |= ((3<<12) | (3<<14) | (3<<16) | (3<<18) | (1<<24) | (1<<26));

LCD_CFG_REG = 2;
LCD_TIMH_REG = ( (0<<24) | (0<<16) | (50<<8) | (((320/16)-1)<<2));
LCD_TIMV_REG = ( (0<<24) | (0<<16) | (1<<10) | (240-1) );
LCD_POL_REG = ( (1<<26) | (((320/1)-1)<<16) | (1<<12) | (0<<5));

LCD_CTRL_REG = ((1<<5) | (6<<1));
LCD_CTRL_REG |= (1<<8);

LCD_UPBASE_REG = BUFFER_ADDR;
LCD_LPBASE_REG = BUFFER_ADDR;
for(i=0;i<50000;i++);

LCD_CTRL_REG |= 1;
for(i=0;i<50000;i++);
LCD_CTRL_REG |= 1<<11;
}

I have little big different probleme. We are sure, that data is right write to VRAM (SRAM) area, but DMA LCD Controller does not read correct and finally pixels picture erroneously. Do you know, what can be wrong, if DMA does not correct read data from SRAM to show on display ? Thank you
