Lanstone install failed

Post by g8gtz » Sun Oct 04, 2020 3:16 pm

Hi

I rebuilt a card a couple of weeks ago and whilst P4 works, it just hangs on the Langstone splash screen - everything connected and has run previously.

I used this process from a previous post:
SSH into the Pi
cd Langstone
ps -ax

Make sure you can see the following programs in the list:-

/home/pi/Langstone/Lang_TX.py
/home/pi/Langstone/Lang_RX.py
/home/pi/Langstone/GUI
None of these appear to be in the list.

As your installation is failing I suspect one or more of these will be missing.
Try doing the following.

./stop
Resulted in :no process found
python Lang-TX.py & Should run the TX task. It will display a task ID Number and a message about the audio source.
Result was Can't open file {Errno 2} No such file or directory

Looks to me like the install failed but the "Install Langstone" button is greyed out...

Thoughts?

Very interesting, Join the club!

Yesterday in preparation for boxing up the langstone hardware, I checked that my standalone langstone built in may 2020 worked fine, which it did then i built a new card and installed the latest Langstone standalone version as instructed

First few reboots I got pluto.local not found and those 3 processes you list didnt start. Went away, had supper, came back, rebooted and it came up with the gui, but with 2 issues

1. Scrolling the mouse wheel, the frequency updated about every 3 seconds
2. The touchscreen did nothing

rebooting i now get these issues consistently

so back to the may20 sd card!

Looks like failed Langstone install Noel

My first suggestion would be to update Langstone:

Code: Select all

cd Langstone
./stop
./update
sudo reboot

I haven't made any changes to the install in the last week or so. It was working fine the last time I checked but things outside our control can change!.

I have some new SD cards so I will try a fresh build.

The update routine didn't work so I did a complete install:
wget https://raw.githubusercontent.com/g4eml ... install.sh
chmod +x install.sh
./install.sh
That fixed it and all is working now.

Also, I did a Pluto firmware update and then loaded for the Brave and it seemed to have fixed my Pluto low power issues :D

That's good news Noel.

I have just also done a fresh Langstone build on a new SD card and everything is still working. So the software side still looks good.

The notes about looking for running programs only really apply to a stand alone Langstone which starts up on booting. If you are running it with Portsdown then those programs may or may not be running when you SSH in. Unfortunately running two systems side by side adds complications.

I am thinking about writing a hardware test program which can be run to identify problems. It might take a bit of work to cover all possibilities though. Maybe a separate program for each bit of hardware might be easier.

Most of the lockup problems I have seen tend to be down to the Pluto not responding. It does seem to be very touchy about power supplies and USB connections.
