Hi Umesh@pro3,

 

 

Thank you for letting us know.

 

 

I think that you don't need the pin muxing file, have you tried to use a pin as a GPIO? It could be much easier if you use MRAA to accomplish this, take a look at this link: https://github.com/intel-iot-devkit/mraa/blob/master/docs/joule.md, you can check the Pin Mapping there, and use pins as GPIOs.

 

 

I hope you find this useful.

 

 

Have a nice day.

Hi Umesh@pro3,

You can use any pin shown in the MRAA documentation that I gave you before as GPIO to light up the LED, but the pins produce 1.8V only, so a compatible LED should be used. You can also use the pin as GND, but if you do this then ON will be inverted to OFF.

We also have a patch that can be helpful for you, it is attached to this reply, but you have to consider that the latest supported OS is the Reference Operating System for IoT, and you can download it from here: https://software.intel.com/en-us/iot/hardware/joule/downloads https://software.intel.com/en-us/iot/hardware/joule/downloads.

If you want to use interrupts from the GPIO pins you can only use the pins in the connector J12: 23, 25, and 27.

I hope you find this useful.

Have a nice day.

Regards,
