A PCRE internal error occured. This might be caused by a faulty plugin
This page lists the know errors on the gm5x5x5 PCBs. There are no known issues with the bulk order run (white pcbs), the following information is valid **only** for the prototype run (green pcbs). ==== Prototype Run ==== === #1 MIDI IO pins === **Problem**: The MIDI IO pins of the midi sockets (Pin 4 + 5) are switched. **Solution**: Either (1) use the pin-headers if you use sockets that are not mounted on the pcb or (2) break the traces to pins 4 + 5 of the sockets and solder wires to them or (3) solder the midi sockets on the other side of the pcb. === #2 MISSING TRACK === **Problem**: A track between D2 and R3 is missing. {{:err_2.png|}} **Solution**: Bridge the pins.
