dear Juan Gonzales
I am debugging C:\dvsdk_1_00_00_19\PSP_0_05_03\pspdrivers\system\DM6437\bios\dm6437_evm\src\video\sample\loopback, but there is a problem, the screen is green,no other colors,I just edited one parameter, I changed the value of VPFE_ExtVD_BASE 0x800000u into 0x0,when it was set as 0x8000000u,there was no output video,I don't know how this value is set,so set it as 0,the following is a photo of my screen.now,i am sure my board and ccdc is good.
