Hello list,
Trying to create a device driver for a raspberry pi zero (BCM2835) to control a gpio and an spi device.
This eventually will be done in a FIQ interrupt handler.
A simplified version of this batradio-driver can be found at:
https://github.com/SietseAchterop/Batradio/blob/master/batradio_module/alloctest.c
Regrettably no answers until now.
I only can add that the same code fragments are used in an example that I found on
https://bootlin.com/blog/fiq-handlers-in-the-arm-linux-kernel/
where it is contained in the probe function of the platform driver.
Is there maybe a better place to ask for help here?
Thanks,
Sietse
