pinmux and overlay not found

[John Leung]

Hi,
Following your wonderful post at https://www.zeekhuge.me/post/ptp_blinky/. I'm running BBGW, 4.4.30-ti-r64, Debian 8.6, 2016-11-06.

I've got pru_rproc running, followed the steps, and run
./deploy.sh in the pru_blinky directory.

After successful linking, it echoes:

Finished building project: PRU_gpioToggle
******************************************

-Placing the firmware
-Configuring pinmux
P8_45 pinmux file not found!
P8_45 overlay not found
...

I'm new to BB. Am I missing something obvious that the tutorial didn't spelled out?

thanks.

Got rid of pinmux and overlay not found by replacing dtb built by dtb-rebuilder with the default BBGW 4.4.30-ti-r64 dtb. No more error msgs but LED did not light up on P45.

Got LED to light up after replacing resister with 150 ohms one. For reference, the rebuilt dtb still got LED to light up even with the not found msgs.
