I have been enjoying driving my APA102 RGB LED strip from Omega (first version), using just two wires (and GND, of course): MOSI on GPIO #18, and SCK on GPIO #6 .
Now I'd like to migrate my project to Omega2+. So, I connected the LED strips GND to Omega GND, data line to GPIO #8, anc clock line to GPIO #7 (following the pinout). First thing to notice was that Omega apparently sends some data at boot because ~30 first pixels of the LED strip are twinkling in various colors. Then, it turns out it has not booted properly, because when I attempted ssh login, I found myself in some broken shell (no banner). Rebooting with the SPI wires disconnected resulted in a corrupted boot so that finally I was forced to do factory reset.
I am surprised that such a supposedly simple thing resulted in such a challenge.
