Hi!,
I'm follow this tutorial, but I can't enable the PRU output
root@beaglebone:~/rfsend# config-pin p8.11 pruout
P8_11 pinmux file not found!
Pin has no cape: P8_11
After some research in the forum I think maybe it's a problem with the kernel version, but I have no clue
In /boot/uEnv.txt this is line is uncomment
uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo
This is my system (beaglebone green wireless)
sudo /opt/scripts/tools/version.sh

The old version of u-boot in the eMMC is blocking u-boot overlays from

working correctly..
sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10
Then reboot and it'll work just fine..

now config-pin p9.25 pruout it's working now but I need to use p8.11 as PRU
root@beaglebone:~/rfsend# cat /sys/devices/platform/ocp/ocp\:P9_25_pinmux/state
pruout
how I can use p8.11 as PRU ?

You'll need to make a choice:
PRU or WIFI...
P8.11 is gpmc_ad13.mmc2_dat1
https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/BB-BBGW-WL1835-00A0.dts#L25
You can kill wifi via:
disable_uboot_overlay_wireless=1

Thanks Robert for the script.
If wifi is in 1-bit mode, does it affect its operation ?.
I've already had problems with wifi and the beaglebone green wireless seeedstudio, I do not want to get worse.
I think it's best to modify the 433 mhz tutorial script to use another PRU pin.
In the tutorial (step 3) this is installed, will it be necessary?

In theory it's be 25% as fast...

thanks Robert, I'll try this 1-bit mode
about the PRU now it's working. I change to kernel 4.9.88-ti-r108 and then apt-get upgrade
I recommend this updated guide to understand PRU
