[SOLVED] Enable SPI

kevink

I have been trying to get a zigbee module to interface with the UPboard over SPI for some time.
I've had success across USB using the pySerial library and I am trying to convert my code to be used on SPI with the MRAA library and I have the error: "Spi bus can not be initialized".

I think my problem may be that the module is not enabled in the kernel as /dev/spidev0.0 does not appear. I've followed the instructions on the wiki page as well as the correction found here: https://forum.up-community.org/discussion/comment/8488#Comment_8488.

Before I start digging around the kernel I wanted to see if I've exhausted all my options to make spidev appear.

Source:
dev = mraa.Spi(0)

Output:
ValueError: Error initialising SPI bus

OS Version:
Ubuntu 16.04 LTS

Are you using the Up-board kernel (find out with 'uname -r')?

I followed the instructions to reinstall the upboard kernel here: https://wiki.up-community.org/Ubuntu

when I run "uname -srv" it returns:
Linux 4.10.0-42-generic #5000~upboard11-Ubuntu SMP

It seems that reinstalling the kernel has worked. Thanks.

EDIT: How do I mark this as resolved?
