[SOLVED] Pypilot on RP4 with Moitessier - Max1947 - 2020-05-10
Hi everyone. A small problem with Pypilot on RP4 with Moitessier. I have to start RP twice to get Pypilot to hook and see in SignalK it transmits. When first switched on, nothing. I restart and Pypilot engages and signals in SignalK. Does this happen to you too?

Hi everyone,
I have the same problem with the latest packages - I think it has to do with some I2C problems, because the effect is that GPS/AIS on the HAT2 still works, but everything using the I2C bus stops working (pressure, temperature, PyPilot roll/pitch/mag. heading).
If I dig further into it I see the following problems on the Pi4:
[...]
[ 850.578567] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[ 851.618668] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[ 852.658870] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[ 853.698860] i2c-bcm2835 fe804000.i2c: i2c transfer timed out
[...]
and
i2cdetect -y 1
just hangs or outputs the result very very slowly.
Once finished the address 68 is missing from the output.
Hardware: Raspi Pi 4, HAT2, directly connected without any adapters/cables.
Software versions:
ii openplotter-can 2.1.1-stable all OpenPlotter app to manage CAN BUS adapters
ii openplotter-dashboards 2.2.0-stable all OpenPltter app to manage dashboards
ii openplotter-doc 2.0.7-dev all OpenPlotter project documentation
ii openplotter-i2c 2.1.1-stable all OpenPlotter app to manage I2C sensors in Raspberry Pi
ii openplotter-mcs 2.1.6-stable all This is a App for Openplotter 2.0 and higher to use with a GeDaD MarineControlServer Hardware
ii openplotter-moitessier 2.1.2-stable all OpenPlotter app to manage the Moitessier HAT
ii openplotter-network 2.1.4-stable all OpenPlotter app to manage network connections in Raspberry Pi
ii openplotter-opencpn-installer 2.1.0-stable all OpenPlotter app to manage OpenCPN installation
ii openplotter-pypilot 2.0.8-beta all OpenPlotter app to integrate Pypilot in Raspberry Pi
ii openplotter-serial 2.1.0-stable all OpenPlotter app to manage serial devices
ii openplotter-settings 2.3.0-stable all Main OpenPlotter app
ii openplotter-signalk-installer 2.1.0-stable all OpenPlotter app to manage Signal K node server installation
Strange thing is that after power-on it works for 1-2 minutes - then it stops. Soft reboot seems to help as it is running stable for about an hour now.
Best regards,
Jonas

This is how it looks like once the HAT2 I2C stops working:
root@openplotter:~# i2cdetect -y 1
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- UU -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- UU UU -- -- UU -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- 77
GPS/AIS is still working without problems in that moment.
RE: Pypilot on RP4 with Moitessier - Sailoog - 2020-07-15
This should be fixed on next update of openplotter-i2c app. thanks.
RE: Pypilot on RP4 with Moitessier - Sailoog - 2020-08-13
This should be fixed in openplotter-i2c 2.1.2, please update (the package is currently being built on the server and should take half an hour)
Marking this problem as solved, reopen if necessary.

Hi Sailoog,
thank you very much for the update - I installed yesterday and since then it is running stable - will monitor during the next days and give another update.
Best regards,
Jonas
