Release of P2 Octo Serial port driver

(Update: same as v1.0.0 but disabled use of Logic Analyzer Characterization Pins 4, 6, 8-10)

  • Services 1 to 8 ports from single cog running Pasm2
  • Tested initial configuration: 115,200 bps, N81
  • Validated with serial decoding logic analyzer
  • Tested Raspberry Pi <-> P2 - two serial pairs
  • Tested P2 <-> P2 - six more serial pairs

Known Issues

  • We need to characterize this now that it's mostly working
  • We saw one issue with the 2nd serial port connected to a test RPi 4. The second serial port started the first transmission with a leading 0x00 byte. The cause has not been found.
  • When testing P2 <-> P2 with many ports we saw no such issues as is the same with the first of the two serial lines connected to the RPi
