Raspberry Pi Forums

I am trying to get GPIB to work on an RPi B+, following this guide:
https://www.element14.com/community/peo ... ment-79630

To use linux-gpib, I need the kernel headers, and the newest ones seem to be the ones of version 3.18. I installed those using However, using that kernel, my SPI pins stop working shows no devices.
When going back to the 4.X kernel, SPI works again.
I was reading that something regarding "device tree" changed in version 3.18, but it's not clear if 3.18.0 was before or after that change.

I would be grateful for any tips on how to get SPI to work with the 3.18.0 kernel, or where to get up-to-date kernel headers, so I can use them to build linux-gpib

Thanks

Use rpi-source (https://github.com/notro/rpi-source / https://github.com/notro/rpi-source/wiki)

This did indeed work, thank you very much.

Communicating with a GPIB device using sudo ibtest works.

I still have problems with pyvisa and pyvisa-py, but that is a different problem.

Thanks so far
