TDA3MV: After setting EVE_900HZ, Displaydrv ERROR

Part Number: TDA3MV

Hello

I'm using TDA3xMVS.

I set  SBL_LIB_CONFIG_DSP_1000GHZ_EVE_900MHZ to 1u in sbl_lib_config_tda2xx.h.

Before entering the usecase, the frequency is as shown below.

However, when entering the usecase, the following error occurs:

There is a phrase like below. Is there a way to solve the problem by setting eve to 900hz?

    Hi,

    What's the display pixel clock requirement? If i remember correctly, this clock was shared for DSP, EVE and pclk and so it was limiting the pixel clock to either 150MHz or 75MHz. If you are using any other pixel clock, it would not work. 

    Do you also use Ethernet? Because if not, then we can use Ethernet clock for one of these modules and can then get the any pclk for display. 

    Regards,
