I use DVRRDK_04.01.00.02 and u-boot-dvr-rdk
The default uboot logo works find, on 640x480 HDMI mode.
I must use 1024x768 XGA mode.
So I change "common/cmd_logo_816x.c"
=== FROM ===
/* Configure HDMI and HDDDAC VENCs for 640 x 480 @ 60 */
configVenc(0x6000, 0x2, argv[0], 640, 16, 48, 96, 480, 9, 34, 2);
configVenc(0x8000, 0x0, argv[0], 640, 16, 48, 96, 480, 9, 34, 2);
configVenc(0xA000, 0x1, argv[0], 640, 16, 48, 96, 480, 9, 34, 2);
=== TO ===
/* Configure HDMI and HDDDAC VENCs for 1024 x 768 @ 60 */
configVenc(0x6000, 0x2, argv[0], 1024,24,160,136, 768, 3, 29, 6);
configVenc(0x8000, 0x0, argv[0], 1024,24,160,136, 768, 3, 29, 6);
configVenc(0xA000, 0x1, argv[0], 1024,24,160,136, 768, 3, 29, 6);
for the pixel clock setting for resolution, and I must change PLL clock from 27.2MHz to 65MHz
at the function
void HdVpss_VencD7425_VencA7425(void)
{
WR_MEM_32(CM_CLKOUT_CTRL, 0x0);
VideoPLL(0x6E, 0x2, 0xB, 0x0, 0x5, 0xF, 0xB6DB6D, 0x1E, 0xF, 0xB6DB6D, 0x1E, 0x0, 0x0);
}
How can I set PLL clock to 64MHz on VideoPLL(.XX.XXX.XXX) ?
Best Regards
Larry..
