Having a problem with my MacArthur Hat.
I have it connected to a RP5 with NVMe bottom / 500GB drive. The power module is installed and have the IMU inserted on the MacArthur board. Printed enclosure with lots of openings and no top so is not getting too hot. Have ethernet (for Halo radar - working). Have o-charts dongle. HDMI but normally use it headless.
My system initially was playing well. Check system passes no issues. I could see traffic through the board within SignalK. Testing it on a bench before I take it to the boat. 12V into the board. 12V SW with open/closed switch to set the power on/off (like this functionality!). No power at USB-C input. MCP251xfd set to SPI0-CE1/200000/GPIO25 (was available) / can0 / can0 when added SignalK connection. No other CAN0 configurations.
It was ‘working’ where I could save a configuration but then I started having issues where could not get NMEA2000 to see the network. Shares common 12V power for N2K backbone and power to Pi5 through MacArthur hat. Impedance for N2K connection is correct at 62 ohms across the +/- for the NMEA2000 connections. Then the board decided to cycle itself a few times - it would cycle the whole system. It is drawing 480mA at full load (variable power supply is set to 12.6V and is 10A so not an issue).
So thought maybe the power supply board was U/S. Powered system down. Took power supply daughter board off. Rebooted without the power daughter board with only USB-C with a separate 5A power supply directly to the Pi5. This works for the Pi5 but the MacArthur hat appears to now not be working at all. The NMEA2000 LEDs are showing steady lights (no blinking) so the network is not working even though the configuration shown above is valid (did try removing / installing again configuration wise). And no additional lights on the MacArthur board - I would have thought 5V would have lit up. I know the network is working fine as when I use Yacht Devices USB device, I can see the traffic (GPS and wind sensor showing)
I can use my Pican-M board which seems to be more resilient but was hoping to use the MacArthur board as it has graceful shutdown, and much more capability with other interfaces.
Any thoughts on trouble shooting would be appreciated or perhaps my MacArthur board is U/S. My Pi5 / Pican-M / NVMe 500GB drive configuration is working fine.
