SK-TDA4VM: GPIO_Led Blink

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

Hi,

SDK 8.0


we are trying to develop an application that requires the exposed GPIO pins available on the TDA4VM processor starter kit.
we would like to know the procedure to build and run the application from MCU1_0. We tried to use the GPIO_led blink demo application as the starting point.

    Hello Sam,

    To clarify, your setup is using PSDK RTOS 08.00.00.12 on the SK-TDA4VM (blue board)? And the goal is to run some baremetal code on the MCU1_0 that will interact with the GPIO pins, such as the GPIO_LedBlink demo available in PDK?

    And we do not want to use the A72 to control GPIO through Linux?

    Regards,

    Takuma

    Hello Takuma,

    -Yes we are trying to use the PSDK RTOS 08.00.00.12 on the SK-TDA4VM (blue board).
    -We are trying to run tirtos code on MCU1_0 that can access the GPIO on the board and communicate with Linux on A72 using IPC communication.
    -No we want the MCU1_0 to read/write the GPIO pin, process the data, and then send a message to Linux.

    Hello Sam,

    -Could you give me a day to confirm with the team that TIRTOS demo is supported on the SK-TDA4VM?

    -PSDK RTOS 08.00.00.12 was developed for the TDA4VM-EVM, so many demos included with that PSDK do not work on the SK-TDA4VM due to board difference.

    Sincerely,

    Takuma

    Hello Takuma,

    - sure we will wait for your response. 
    - while trying to run the application on TDA4VM-EVM we faced boot failure and some log on the MCU UART terminal.

    Hi Sam,

    I had a meeting with the developers about running RTOS demos on SK-TDA4VM. In summary:

    • RTOS demos have not been validated on the SK-TDA4VM and we have no plans to validate or support RTOS development on the SK-TDA4VM board.
    • When developing RTOS applications, please use the TDA4VM-EVM even if it costs quite a bit more than the SK-TDA4VM.
    • SK-TDA4VM is mainly for quickly evaluating the performance of deep learning models on the TDA4VM SoC, by providing the Edge AI SDK which is a bootable prebuilt Linux image that allows customers to easily swap out the models used in the demos with their own model.

    If you are trying to develop RTOS applications on the TDA4VM-EVM, we do support that. And if you are facing a boot failure, could you create a new E2E post with the logs posted?

    Regards,

    Takuma

    Hi Takuma,

    Thank you for the update.
    I will create a new thread with log of boot failure with reference to TDA4VM-EVM.
