How to raise interrupt from ARM to PRU

Hello!

How can one raise interrupt in the PRUSS INTC? All of the examples are written for the older uio_pruss driver.
I’m currently running on 4.1.17-ti-rt-r45 kernel.

I have a line which says:
[ 11.690119] pruss-rproc 4a300000.pruss: 8 PRU interrupts parsed
I searched through the sysfs, but I cannot access these interrupts.

Anyone have experience with the newer driver?

Thank you

Hi Bálint!

You could switch your kernel to the bone channel and continue to use uio_pruss:

`

cd /opt/scripts/tools/
git pull
sudo ./update_kernel.sh --bone-rt-kernel --lts-4_1

`

Then reboot.
