TDA3XEVM: HDMI CPLD MUX

Anil Kumar23

Part Number: TDA3XEVM

Hi,

From the TDA3 EVM schematics it is clear that there is a cpld mux between processor and HDMI transmitter. I2C1 is used for configuring HDMI  transmitter in TDA3 EVM.

In our custom board design,vout pins from processor are directly given to HDMI transmitter,I2C is used to configure the HDMI tx.

From the software I have tried disabling the Bsp_boardSelectModeTda3xx() function ,but it is not working.

Can you suggest me with solution?

Regards,

Anil

    Hi Anil,

    could you please tell which application you are using to bringup the HDMI Tx?
    In addition to SelectMode, you need to look into Bsp_boardGetVideoDeviceInstId, Bsp_boardGetVideoDeviceI2cInstId, Bsp_boardGetVideoDeviceI2cAddr, Bsp_boardPowerOnDevice, Bsp_boardSelectDevice and Bsp_boardResetDevice APIs to make sure they return correct values for the HDMI Tx.

    Hi Brijesh,

    Thanks for the reply.

    I will look into the functionality of those API's and check their return return values.I'm trying to run the ISS usecase present on the SDK.
