  Hi. I installed mraa form https://docs.ipi.wiki/iot_pi/. The linux pin numbers are reported as invalid (234 - 262). What is correct?

  Hi Graham, can you try our Debian image or Yocto image, it has MRAA pre-installed already.

  Is "The linux pin numbers are reported invalid" an error message you see in the terminal? If yes, you might be running this software on another board?

  We also need to install wxpython and were unable to do so on the Debian image. Will any numbers work with ubuntu? I tried some random values.

  The iPi runs on ARM, so when https://docs.ipi.wiki/iot_pi/HowToInstallMRAA.html failed in python "mraa.Gpio() not recognized), I ran the install at http://iotdk.intel.com/docs/master/mraa/python/ which does not accept any pin number as valid. Any suggestions please? Graham
