intc-test.py is a more involved example that showcases sharing a data structure (in pruss local memory) between python code and the PRU cores, and sending events from both pru cores via the pruss interrupt controller to event handlers in python.elf-test.py demonstrates how to load an ELF executable produced by clpru.ddr-ping.py is a small test of using a shared DDR3 memory region.basic-test.py is a minimalistic example that initializes register R0 of a pru core to 123, loads and executes a tiny pru program that increments R0, and then reads back and prints R0 (which should therefore print 124).

Now you can try out the various pru-examples:

Update your initramfs with sudo update-initramfs -u (unless you're not using initramfs).BeagleBoard-X15 and BeagleBone-AI only: #include dra7-uio-pruss.dtsi into your dts and recompile the dtb.Uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo BeagleBone (except BeagleBone-AI) only: Make sure the your /boot/uEnv.txt enables uio-pruss by setting.This will create symlinks (in /dev/uio/pruss/) toĪllow the uio-pruss devices to be located easily. To uninstall simply use pip3 uninstall py-uio. Need to reinstall the package after pulling changes. Installed in the python path rather than copying files, which means you don't The -e option causes a symlink (of sorts) to be Or, if you've already cloned the repository, you can install it with
