Ryde problems

I am testing a symbol rate scanning Ryde receiver for GB3ZZ and am having great trouble getting it to operate in a stable manner. The problem is that after a period of correct operation, it comes up with "Longmynd not loaded" and then requires a reboot.
The Pi is operating on 5.25V and the low voltage lightning symbol never appears. Today, I have completely rewritten the card with the latest software.
I have been told that this problem occurs if the Minitioune board is unpowered or not correctly connected by USB. Minitioune is correctly powered. I have plugged it into a PC with Minitioune software and it works well. I have tried two different USB cables which are quite short and they both work well.
G4BVK has had similar issues with "Longmynd not loaded" coming up at times. I am out of things to try now and hope that perhaps the experts can shed some light on this problem.

Hi Shaun,
This sounds like longmynd crashing for some reason or outputting an unexpected error. Can you reproduce it reliably? as it should output some debugging information when it crashes if you run it directly.
To run it directly shutdown the app from the power menu then run the following from the ssh console.
Code: Select all
cd /home/pi/ryde
python3 -m rydeplayer /home/pi/ryde/config.yaml

Thanks Tim,
I will try this and report back.

Tim,
I have emailed you direct because the text is too long for the forum.

Thanks Shaun,
The relevant bit turns out to be the bit at the end:
Code: Select all
Flow: No-data timeout, re-init config.
Flow: Config cycle: Frequency [0] = 1249000 KHz, Symbol Rate [2] = 2000 KSymbols/s
Flow: NIM init
Flow: STV0910 init
Flow: stv0910 init regs
Status: STV0910 MID = 0x51, DID = 0x20
Flow: STV0910 set MCLK
Flow: Setup equlaizers 1
Flow: Setup carrier loop 1
Flow: Setup timing loop 1
Flow: Tuner init
Flow: Tuner cal lowpass
Flow: Tuner set freq
Status: tuner:0, f_vco=0x261dd0, icp=0x1, f=0x22222, n=0xa6,
rdiv=0x1, p=0x0, freq=1249000, cfhf=4118
ERROR: tuner wait on lock timed out
ERROR: Tuner set freq 1249000
ERROR: Failed to init Tuner 1249000, 0
ERROR: failed to init a device - is the NIM powered on?
Longmynd thinks its a hardware fault but it could also be a Longmynd bug.
How long does it take to fail usually? Is there anything unusual about your hardware setup? Just trying to work out if I can make my pi do it.

Tim,
Today it was failing within five minutes. Ken G4BVK is having similar trouble. It is an absolutely standard mk.II Minitioune board fed from a good quality 12V bench power supply.

I am putting together a Ryde and successfully loaded the firmware to the Pi-4, as far as I can tell. But, having done all this, the receiver no longer seems to appear on the network.
It starts, displays the Beacon, the push buttons seem to work and I am now looking to configure the receiver for a remote control. But, looking on the network it is not there (yes, Ethernet is connected) so I can't SSH into it.
Any ideas?

PS Also, to make things easier, it would be useful if one of the Ryde menu's displayed the IP address. As it is, I don't find 'Advanced IP Scanner' that effective sometimes and have to interrogate the router directly.

Hi Jen
Pleased that it works.
If you go to the power menu, and shtudown the App (not the system), you should see the IP address on the screen about 10 lines up from the bottom. You can then log on and type menu to get into the configuration menu.
Displaying the IP address is already on the Issues list:

Hi Dave,
thanks. I tried what you said and still couldn't see the IP address. Both lights are on with the Ethernet port. What am I missing ? Please see photo attached.

Hi Jen
How did you build the card? Did you log in to it across the network by ssh? Or did you use a keyboard?
