The environment of the board we use is: SDK of tda4ve j721s2 version 8.4. We use the edp interface on the board for output and use the edp->hdmi converter. The crystal oscillator used on the board is 24MHz. I've changed the definition in the drv/dss/src/ file to 24MHz, but there are still some problems.
1. In the log of vision_apps, I can see that the display has been detected: DSS: isDpConnected = true. But there is nothing displayed on the screen when I run './run_app_dof.sh'.
2. Have you verified the 24MHz crystal oscillator input? After I open the REF_CLK_24MHz definition, the default pdk compilation will report an error.
