![]() The additional info will help understand and tune the GPU better. The good news is I did recently get clinfo to work correctly, and it reports a bunch of information on the Mali GPU, which looks great. py code doesn't work so I'm going to open a discussion over at N2. Here’s what happens when you run clinfo on an ODROID-XU4: sudo apt-get install clinfo sudo clinfo Number of platforms 0. The problem with the N2 is that I can't get the MAXX7219.py code to work with it. ![]() This exact same setup with 12 matrices (96 x 8) on an N2 worked just fine. I tried troubleshooting the signal lines, MOSI, SCLK and CE0 and I didn't resolve anything in particular but I was favoring the SCLK line as the probable issue. I even tried adding a separate 5v supply with 2.4A available to the power input of a 72 x 8 array and the LEDS still garbled. MongoDB is giving me a hard time, broken dependencies. I followed different tutorial, but no luck with those no brain tutorial. Of course I needed to modify the code for the dot_shift_test.c to incorporate more matrices. I'm having hard times installing Ubiquiti Unifi Controller on Armbian (running on a XU4) Armbian version : Armbian5.59Odroidxu4Debianstretchnext4.14.66. This is with both 16.04 and 18.04 as well as using the dot_shift_test.c and a Python 2.7 LED Matrix code (MAXX7219array.py) One issue I have discovered with the XU4 is it's limitation with the number of 8x8 LED modules that can be cascaded.Īny more than 8 modules cascaded, essentially creating a 64 x 8 array, the XU4 / Shifter Shield will load and garble will ensue. ![]() I successfully installed SPIDEV for the XU4 and also for WiringPi as well by upgrading to 18.04īoth work fine with dot_shift_test when compiled from dot_shift_test.c with either the #define USE_WIRING_PI_LIB enabled or commented out.
