Unblocking ports on Intel Joule - SPI

Please help me to unblock the SPI ports on my Intel Joule device!

To anyone reading: calling intel technical support on the phone does not work.

I just want to write code, super frustrating!

I first found out about this because of: https://askubuntu.com/questions/878445/error-illegal-arguments-for-construction-of-exports-spi%23com... https://askubuntu.com/questions/878445/error-illegal-arguments-for-construction-of-exports-spi# comment1401949_878445

Operating System:

Ostro that ships with device:

Intel ref-os-iot in live mode

After install ref-os-iot to the EMMIC

When I try to use the SPI ports across languages:

In python:

I tried the same for `m.SPI(0)`

In Node.js:

Jose,

Happy to bring this to your attention. Is this normal? Is this Joule actually production ready? What linux distro should I be using that has stable interfaces?

Thanks so much!

Hey!

Is there anything i can do to help? This has become a critical dependency falling behind schedule and im extremely motivated to get this working. Are other people able to use the SPI port? Is this just me?

Thanks,

AJ

Three months and still no fix? Wow! I just bought an Edison board so I can start writing some of the firmware and get experience with mraa.

Sounds like this is not going to get solved anytime soon.

Intel, please invest more resources so we can actually make with your tools!

Jose I looked at your private message and will answer when the SPI port is working
