SK-TDA4VM: Example syscfg file for SK-TDA4VM

Part Number: SK-TDA4VM
Other Parts Discussed in Thread: TDA4VM, , SYSCONFIG

Hi TDA4VM Champ!

My customer asked about template syscfg file for SK-TDA4VM.

Can you please provide us with the template file of syscfg fot SK-TDA4VM?

And is it possible to use SYSCONFIG tool to change the voltage level of a particular pin? It seems not allowed to change the preferred voltage in the tool.

 

Can you please show how to change the voltage level of a specific pin? via DTS? give a simple example.

Thanks.

Regards, 

Jack

    Hello Jack,

    Currently, the .syscfg template file for the SK-TDA4VM is not available. I will investigate availability further; in the meantime, please use the schematics as a reference to create a base configuration for the SK-TDA4VM.

    In the SysConfig PinMux Tool, please add a Power Domains configuration to enable preferred voltage for each peripheral. The Power Domains configuration section itself is used to specify each domain's voltage.

    By changing the voltage level per pin, do you mean, for example, a GPIO outputting high or low?

    Regards,
    Mark

    Hi Mark.

    Thanks for your kind answer.

    My client would like to set the voltage level of a particular pin, but if that is not possible, please let me know how to modify the voltage level of the full power domain to which that pin belongs. 

    Please tell me one example of modifying it in SYSCONFIG or DTS file.

    Thanks.

    Regards, 

    Jack

    Hello Jack,

    Yes, the voltage level of the whole power domain will be affected-- individual pin voltage level control is not possible.

    For power management within the DTS, please see this thread: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/535886/how-do-you-setup-the-regulators-in-the-device-tree

    To clarify SysConfig PinMux Tool's functionality: The tool generates a pinmux and its correlating PADCONFIG register configuration. It does not generate an output that will affect the voltages of the power domains. The preferred voltage and power domain voltages in the tool will highlight any conflicts with the user configuration. For example, if the user sets the RGMII5 (VDDSHV3) to 3.3 V and then prefers 1.8 V when using RGMII5, the tool will produce a "Voltage conflict" warning to alert the user when they want to use RGMII5. However, if "Use peripheral" is set to "Any," then the tool will select a peripheral which matches the preferred voltage.

    In the Device Settings -> Power Domains view:

    In the Peripherals -> RGMII view:

    Please let me know if I can clarify further.

    Thanks and regards,
    Mark
