Mounting/Accessing SD-Card on BBB

HI Christian,
This was very helpful as always.
But I think I didn't explain enough.
The PRU driver runs just fine I was able to load code onto pru and wait for
its return via interrupt.
I could also show that it runs the exact expected amount of time.
So no problem there.
The other thing I am trying and where I fail is:
First I route interrupts to a file.
With these four commands:
sysctl dev.ti_pruss.0.irq.2.channel=2 # mapping channel 2 to irq2
sysctl dev.ti_pruss.0.irq.2.event=16 # mapping event 16 to irq2
sysctl dev.ti_pruss.0.irq.2.enable=1 # enable the irq2
sysctl dev.ti_pruss.0.global_interrupt_enable=1 # enable PRU global
interrupts
After that I get the device /dev/pruss0.irq2.
And I want to read the interrupts from this file with the code you saw.
Obviously the interrupts are triggered by code on the PRU.
This is the proof of concept FreeBSD used.
https://reviews.freebsd.org/D11959
But maybe the test I already ran is proof enough.
And this could also be a problem with the sysctl command.
Best,
Nils
