Dear all
SPI master is not working any more after installing the latest raspbian-2017-12-01. It runs perfectly well with previous version (https://downloads.raspberrypi.org/raspb ... 017-09-08/ kernel 4.9.41-v7+).
It seems that the SPI kernel 4.9.59-v7+ interface has changed in RPi side creating the need for a change in CODESYS run time. Something to do with clock divider, maybe. I tried setting SPI master parameter _dMaxSpeed to several different values, no effect.
I have tested with Piface OI driver, but all hardware using SPI interface would be affected and that is why I would like to 3S personal to take measures.
Thanks

Hi,
yes, the workaround is to reduce the SPI maxspeed in
the CODESYS configuration.

Hi
I have tried it, but it did not work. Even reloading the application. Any additional hint?
Hi,
I use:
this works for me!
