rtdm spi demo on Raspberri pi

rtdm spi demo on Raspberri pi

[Ho Tam]

Hello group,
I can see there is rtdm spi driver for raspberry pi but can't see any
userspace demo for it.
I have built and inserted xeno_spi_bcm2835, xeno_spi modules but couldn't
see any spi device in '/dev/rtdm/'.
Does anyone have example using this driver?
Thank you

I've played with it a bit, I'll see if I have any example code laying
around.  Did you unbind the linux spi driver?

Thanks

Yes, linux spi driver has been isolated. I am waiting for your example code.
Thank you,

I haven't been bale to dig up my example code for this but I base it off
this test:

https://gitlab.denx.de/Xenomai/xenomai/blob/master/testsuite/spitest/spitest.c

I'll hopefully have some time in the very near future to put together a
quick example.

Thanks

Greg
