Hello all:
I want to show a raw RGB(5:6:5 format) picture in the u-boot,
which is loaded at BMPADRR . But I see nothing on the screen when set "#if
1". A red background is shown when set "#if 0". The follow is a part of my
code. Is there any incorrect configuration? How to show the raw RGB
picture? Please help me. Thanks very much!
#define BMPADRR 0x80700000
#define BMPWITH 0x000002d0
#define BMPHIGH 0x00000120
#define BMPSIZE (BMPWITH * BMPHIGH * 16)
void davincifb_init( void )
{
#define PLLDIV1 0x01C40918
#define PLLDIV3 0x01C40920
dispc_reg_out(PLLDIV1,0x00008000);
dispc_reg_out(PLLDIV3,0x00008002);
/* Initialize the VPSS Clock Control register */
dispc_reg_out(VPSS_CLKCTL, 0x18);
/* Set Base Pixel X and Base Pixel Y */
dispc_reg_out(OSD_BASEPX, BASEX);
dispc_reg_out(OSD_BASEPY, BASEY);
/* Reset OSD registers to default. */
dispc_reg_out(OSD_MODE, 0);
dispc_reg_out(OSD_OSDWIN0MD, 0);
/* Set red background color */
set_bg_color(0, 62);
#if 1
dprintf("Register OSD0

dispc_reg_out(OSD_OSDWIN0ADR,BMPADRR);
dispc_reg_out(OSD_OSDWIN0OFST,0x0000002d);
dispc_reg_out(OSD_OSDWIN0MD,0x00000002);

dispc_reg_out(OSD_OSDWIN0YL,BMPHIGH);
dispc_reg_out(OSD_OSDWIN0MD,0x00002002);
dispc_reg_out(OSD_OSDWIN0MD,0x00002003);
