I attached a LCD,240*320,not-standard. I need a DCLK at 5.4MHz,I have tried written to VPSS_PLL2DIV1 but nothing changed. When I wrote 0x1 to the PLL2CTL register to enable the PLL2 module, the davinci-evm board died when strting the linux.Just like this: dispc_reg_out(VPSS_PLL2DIV1,0x0004); dispc_reg_out(VPSS_PLL2DIV1,0x8004); dispc_reg_out(VPSS_PLL2CTL, 0x1); //died in here.
I also can get the DCLK with 5.4MHz by written to the VENC_DCLKCTL with a 0x0004, but I think it's not right. And the other two clocks won't be OK. I can get three correct clock with written to the HVALID and VVALID with 240*4 0r 320*4,this is not accordant to the USer's GUild.(VPBE).These two registers should be 240*2 and 320*2, isn't it? But I saw someone attched a 1024*768 LCD just wrote them with 1024 and 768 but not multiply 2. Our hardware is RGB888 but didn't attached the lowest 3,2,3; so it will get a RGB565. My English is poor, hope someone can help me. I puzzled in this problem for so long a time. Thanks a lot.Any clue is useful. -- USTC Alumni Email System
