Hi,
I have been trying to get the spi working on an emulated omap3 with qemu but so
far I wasn't able to complete the cycle. I decided to use spidev in order to
ease things. Here is what I currently did:
I changed the kernel so everything is working on the real overo board. So it is
definitely a qemu problem.I put logging messages into the qemu code to see
where I was stucked at: it is transmitting the spi messages but it gets stuck
in the spi.c at the line if ((dev = bus->device[channel])).From that I think
the bit I'm missing is the initialisation of the spidev device on the qemu
side. I don't know if that has to be defined when launching qemu or if that has
to be created in qemu source code (then where and how?). I haven't been able to
find anything on that subject so I hope someone here can give me a hint.
Thank you for your help,
Johan
