Re: [beagleboard] Re: BeagleBone Black QNX 6.5.0 SP1

The setup I use should be correct since this is the one provided by QNX directly (MLO first, u-boot and image). Moreover, if my setup was incorrect, the prebuilt image could not work. Yes i rebuilt all by following this

Hello, I am receiving errors w/ the .dtbo only. I am too far from outside to communicate w/ my GPS and I am receiving no feedback w/ pyserial on my BBG (BeagleBone Green). I tried installing a serial lib. w/ sudo apt install python3-serial, also. I just downloaded/installed the docs in

You prompted me to recheck how I'm accessing the two peripherals I did get to install, the UART and the I2C. I'm only sending messages out over the UART using pyserial, although I do also use minicom to bi-directionally communicate with the board under test from the BBB Ubuntu command line. For

Hello all, I have a BBB Python application (PCBA test fixture) where I am using libpruio, specifically for access to the eCAP pins. Libpruio requires that the universal cape be disabled, but when I needed a UART and I2C, I was able to add those back in using the existing dtbo files from
