Linux/TDA2PXEVM: How to use PRCM APIs ? (XDC ASSERT)

Part Number: TDA2PXEVM


Tool/software: Linux

Hello

I use TDA2PX and want to get power comsumption of the chip on SW side.
I found PRCM interface and tired to use them.
I just put Utils_prcmPrintAllVoltageValues() in vision_sdk/apps/src/rtos/common/chains_main_linux.c, but some eorrs occured as below

Please let me know how to use PRCM APIs and "XDC ASSERT" in the log.

Or, if I can not use these APIs to meassure "power comsumption" on SW side, tell me the way to get the power state of the chip.

And I want to research PM HAL interface to check PM function body if it is possible... .  Is there the way to research this layer??

Thank you.

    Hi,

    can you check chapter "7.4 Reading Power State and Clock Frequency of the system" in PROCESSOR_SDK_VISION_03_XX_XX\vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_DevelopmentGuide.pdf.

    Also this document might be useful: PROCESSOR_SDK_VISION_03_XX_XX\vision_sdk\docs\TrainingSlides\PowerManagementSoftwareIntroduction.pdf and this Application Note:
    proddms.itg.ti.com/.../sprac22.pdf

    Regards,

    Hi Yordan

    As you said, I already tried to use prcm APIs such as "Utils_prcmPrintAllVoltageValues()" in PROCESSOR_SDK_VISION_03_XX_XX\vision_sdk\docs\FeatureSpecificUserGuides\VisionSDK_DevelopmentGuide.pdf.
    But these APIs are not working....
    Fail log as shown below

    [HOST] [IPU2 ] 18.831421 s: UTILS_PRCM_STATS: Get Voltage Failed!!

    Can you tell me another information?

    Hi,

    Have you set up the I2C to read the PMIC registers for reading the voltage?

    Also, there is a training video for PM, to help you understand the PDK PMHAL.

    Thanks and Regards,

    Hi,,

    Have you set up the PMIC and the I2C for the voltage reading?

    For example call Utils_prcmClockRateInit before calling the voltage read.

    You would also find some details in the training video: training.ti.com/introduction-adas-power-management-software

    Thanks and Regards,

    Hi ~

    I tried to use below functions to ready to call voltage read.
    - Utils_prcmClockRateInit();
    - Utils_prcmPrintPowerConsumptionInit();

    But after running APP, I still faced with xdc assert.

    [HOST] [IPU2 ] 18.846275 s: ### XDC ASSERT - ERROR CALLBACK START ###
    [HOST] [IPU2 ] 18.846336 s:

    [HOST] [IPU2 ] 18.846641 s:
    [HOST] [IPU2 ] 18.846855 s:
    [HOST] [IPU2 ] 18.846885 s: ### XDC ASSERT - ERROR CALLBACK START ###
    [HOST] [IPU2 ] 18.846946 s:

    [HOST] [IPU2 ] 18.847190 s: ### XDC ASSERT - ERROR CALLBACK END ###


    Please kindly explain XDC ASERRT.
    I think ...
    I am not using these APIs properly as well as missing another things such as build env, board configuration and etc~.

    Board : TDA2PX EVM
    Build : Debug build


    Thank you.

    Hi,

    sorry for the delayed reply. Which build config you use? If you use "tda2px_evm_linux_all" can you do the following experiment: modify apps/configs/tda2px_evm_linux_all/cfg.mk and set "ULTRASONIC_INCLUDE=no" instead of "yes" and see if there is a change in the behavior?

    Regards,
    Yordan

    Hi,

    I haven't heard back from you, I'm assuming you were able to resolve your issue.
    If not, just post a reply below (or create a new thread if the thread has locked due to time-out).

    Regards,
    Yordan
