PROCESSOR-SDK-AM437X: OSC chip ID doesn't exist

Part Number: PROCESSOR-SDK-AM437X

I have several ADCs on my board and I describe them in the PinMUX:

But in the generated configuration there is NO any information about ADC:

pinmuxBoardCfg_t gGpevmPinmuxData[] =
{
#if defined(BUILDCFG_MOD_UART)
    {CHIPDB_MOD_ID_UART, gUartPinCfg},
#endif /* if defined(BUILDCFG_MOD_UART) */
#if defined(BUILDCFG_MOD_PRU_ICSS)
    {CHIPDB_MOD_ID_PRU_ICSS, gPru_icssPinCfg},
#endif /* if defined(BUILDCFG_MOD_PRU_ICSS) */
#if defined(BUILDCFG_MOD_I2C)
    {CHIPDB_MOD_ID_I2C, gI2cPinCfg},
#endif /* if defined(BUILDCFG_MOD_I2C) */
#if defined(BUILDCFG_MOD_CPSW)
    {CHIPDB_MOD_ID_CPSW, gCpswPinCfg},
#endif /* if defined(BUILDCFG_MOD_CPSW) */
#if defined(BUILDCFG_MOD_MMCSD)
    {CHIPDB_MOD_ID_MMCSD, gMmcsdPinCfg},
#endif /* if defined(BUILDCFG_MOD_MMCSD) */
#if defined(BUILDCFG_MOD_QSPI)
    {CHIPDB_MOD_ID_QSPI, gQspiPinCfg},
#endif /* if defined(BUILDCFG_MOD_QSPI) */
#if defined(BUILDCFG_MOD_GPIO)
    {CHIPDB_MOD_ID_GPIO, gGpioPinCfg},
#endif /* if defined(BUILDCFG_MOD_GPIO) */
#if defined(BUILDCFG_MOD_RTC)
    {CHIPDB_MOD_ID_RTC, gRtcPinCfg},
#endif /* if defined(BUILDCFG_MOD_RTC) */
#if defined(BUILDCFG_MOD_OSC)
    {CHIPDB_MOD_ID_OSC, gOscPinCfg},
#endif /* if defined(BUILDCFG_MOD_OSC) */
    {CHIPDB_MOD_ID_INVALID}
};

I tried both online and offline versions of the PinMUX, result is the same - NO ADC pins configured, no ADC chips is described.

Is it by design?

How do I read my ADC? I see examples for IDK_AM437x board and there IS ADC present!

};

You can remove OSC from the pin mux tool to get around this. The Tool does not export anything for the OSC module anyway so there is no need to have it added in your pinmux config.

Hi Oleg,

The ADC is missing from the Tool output intentionally. Reason is that ADC pins do not have a pad configuration register. The mux mode is always ADC so we removed it in a recent update. I hope that explains it.

Hi Ahmad,

Thanks for your reply.

It is quite weird that question about OSC is merged with question about ADC. It is totally confusing now, is it me who did this? I'm sure I created a separate topic!

So I created another topic, only about ADC:

https://e2e.ti.com/support/processors/f/791/t/805543

You can reply here or there.

Any examples how can I read those 7 measurements and do not mix them up?

Should I trigger the AD conversion or is it done automatically?

Any help will be  highly appreciated!

Hi Oleg,

You created two threads on OSC and ADC. They were both on the topic of pin muxing similar enough that we merged them and it got assigned to me. Creating a third thread is not necessary if you are satisfied with my previous reply. 

Now you have questions on how to use the ADC, this is a new topic that I am unfamiliar with. For that question it does require a new thread so it can be assigned to the correct person.
