Summary

Upload of actual binaries uploaded to Iris FM1 during Release Candidate 5 (RC5) opportunity on 10/26. Includes both FSW and GSW (backend) used during RC5 since they’re now both tracked on release-candidate.

GSW logs from the various interactions with the Flight Rover (FM1) during this operation can be found in transciever_logs_RC5.zip and packet_prints_RC5.zip.

General Release Notes

  • The Radio was found to be alive during RC5 via Hercules BGAPI Passthrough but it was not (yet) able to be programmed via these means. So, the Radio was not programmed during RC5. Binaries to be programmed remain unchanged from RC3a.

  • Unlike RC3a which used the black IBM dev laptop, the workspace_archives in RC4 and beyond come from the silver Lenovo µHermes laptop used to program in the cleanroom (pulled from ~/Desktop/Workspaces on that machine).

  • REMINDER: Only CCS v9.1.0 is used for programming both the Watchdog and the Hercules at this point.

Operations Highlights

  • Watchdog Transit (RS_KEEPALIVE) bit rate was tuned so it will be <7.78bps with CCSDS headers accounting against our allowance. This leaves enough overhead before hitting our 10bps lander buffer drain rate that we can request diagnostic data without worrying about clogging our buffer.

  • Battery voltages were measured to be:

    • C1: 3.991V (3.991V)
    • C2: 7.99V (3.999V)
    • C3: 11.90V (3.910V)
    • C4: 15.89V (3.990V)
    • C5: 19.88V (3.990V)
    • VBS: 23.80V (3.920V)

  • Boot loop prevention when the jumper is removed without lander power (STORAGE -> FINAL_STORAGE BLiMP modes) was tested now that we seem to be sticking to the 9600baud rate with the lander. Boot loop prevention was confirmed to still work, though comms now cut out after Hello Earth! is received (likely due to the lower baud rate).

  • The connector system for connecting the PICKit to the Radio via the breakout harness has been completely revamped and is now clean and well made. Was rang out but not explicitly tested for fear of corrupting Radio’s now-confirmed-to-exist bootloader.

  • MCLR was confirmed to be wired from the SBC out to the correct pin on the breakout harness (for the Radio programmer).

What’s Changed

  • Added BGAPI receive forwarding from Hercules -> WD -> Ground. by @zCoCo in #156
