Hi!
I’m a newbie to BBB, but have developed code on other ARM platforms, like NXP/freescale, Coldfire, and TI DSP (TMS320x28335). To get my feet wet, I just tried a simple UART PRU app. I’ve tried several examples, such as the BBB Cookbook, and Glenn Lockwoods site, Programming the BeagleBone PRU-ICSS,
But I hooked my 'scope up to P9_24 hoping to see “Hello!” generated, but it only pumps out a single byte every time I load and start the firmware.
I Have the latest debian BBB image loaded on SD. Does anyone know or see anything I’m doing obviously wrong?
Am I being stepped on by Linux drivers I should have disabled?
