Hi,
Question 1 :- I have followed the tutorial which has given in the documentation for visual studio code setup and while build and run the main.py program which comes under src , i am facing isuue “The preLaunchTask deploy-torizon-arm64 terminated with exit code 69” .

Question 2 :- I am trying to access the gpio pins of apalis evaluation board which has apalis imx8qm SoM, i have installed libgpiod library and i wanted to create GUI for that so i am using tkinter for that, but the thing is i am not getting how the pin mapping works , i have seen the datasheet also but i faced diffficulty while understanding the pins .

Thanks

For your first question regarding the error “The preLaunchTask deploy-torizon-arm64 terminated with exit code 69”, this typically indicates an issue with the deployment configuration or environment setup in Visual Studio Code. Here are some steps you can take to troubleshoot this:

  1. Check Dependencies: Ensure that all dependencies required for the Torizon environment are correctly installed on your system.
  2. Verify Task Configuration: Look into the tasks.json file in your project to ensure that all paths and settings are accurate. This file controls how tasks are executed in Visual Studio Code.
  3. Review Output Logs: Examine the output logs for any specific error messages that might provide more insight into what is causing the deployment to fail.

For your second question about accessing GPIO pins on the Apalis evaluation board with the Apalis iMX8QM SoM:

  1. Refer to the Datasheet: The datasheet for the Apalis iMX8QM should provide detailed information on GPIO pin configurations and their corresponding functions. It is crucial to understand this mapping to correctly access the GPIO pins.
  2. Consult Additional Resources: If the datasheet is difficult to interpret, consider looking for community forums or additional documentation that might offer clearer explanations or examples of GPIO pin usage.
  3. Use the libgpiod Library: Since you have installed the libgpiod library, make sure you are familiar with its functions for accessing GPIO pins programmatically. This library will be essential for your GUI development using Tkinter.

If you continue to face difficulties, seeking assistance from community forums or support channels dedicated to the Apalis evaluation board may provide further clarity and guidance.

hi @bandhavyabk

We have an article explaining how to use the GPIOs and how to understand GPIO lines, banks and pins.

We also have a specific tutorial about how to deploy a GPIO application using Python and the Torizon VS Code IDE.
