Transfer failed: PollTimeout

[yo3ggx]

I have a Phantom SDR+ installation working perfectly for a couple of days. Then started to crash with the waterfall showing the same line continuously. Restarting the app solve the issue, but after a few minutes starts to do it again. I let the app off for a week, then when trying again to start it, I get the error:

Transfer failed: PollTimeout
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
and only spectrumserver starts.

Hw configuration: i5 1500T, 32GB RAM, 1TB SSD
OS: Ubuntu Linux 22.04
RX888 MKII.
lsusb shows:
Bus 002 Device 004: ID 04b4:00f1 Cypress Semiconductor Corp. RX888mk2

Any hints on how to solve the issue?

Thank you.

[Bas ON5HB]

Any weird dmesg messages?
Does the stream-driver init the device properly?

How does your toml configured?

Does OpenCL work?

Is the RX888MK2 thermal modified? Else it will die of overheating.

We need a bit more info Dan.

This is from dmesg after ./start-rx888mk2.sh

I'm using opencl, but same message if off.
As stated in my message, everything was working flawlessly for a few days with the same configuration.
The device is not modified, but checked before first run to have the heat transfer pad.

Thank you.

[Bas ON5HB]

I still seems to switch van USB2 to USB3, that is a good sign.

What do you mean it's not modified? The thermal pad and heatsink ARE the modifications, as the unmodified doesn't have those and dies after a few days.

Then it doesn't switch anymore and stays in USB2 mode or not seen at all.

As for OpenCL, it must be compiled in else it doesn't work. If it's not working or installed during compilation, it will not be compiled in and not used.

You can check if it works with intel_gpu_top

How do you start the websdr? Do you use the fifo-way or straight piping?

[yo3ggx]

Thermal pad was there from the beginning.
Compiled with opencl support (opencl installed, including for fft). Was working perfectly with opencl activated.

I try to start it as in the original script (pipe)or fifo-way, same result.

It may be the result of a Linux kernel upgrade, performed during the week, when I didn't try to start PhantomSDR+. Is installed in a remote location. I waited until I got there before trying again. Now I try to connect it to another USB port, or through a powered USB3 hub, with the same result. WebSDR is running on the same server with 7 receivers (5xRSP1a and 2xRTLSDR) without any issue during the same period. If I stop WebSDR server, still the same error occurs. Spectrumserver is running (does not crash), so the web frontend is working.
Currently I'm running Ubuntu 22.04, kernel 6.8.0-57-generic.

[yo3ggx]

After the crash, with Spectrumserver running, I get:

Ok OPenCL is running and working.

What happens if you run on the normal stable kernel and not the latest?

Mine uses: Linux Websdr 5.15.0-135-generic

Can you attach the TOML? As polling error can also occur when fft-binsize is too small.

Mine it this one:

That is for 30MHz wide. Wrong format maybe? As the stream is s16, not u16.

Except personalization stuff, I have the same config as you.
I even try to run again install on a clean clone of the repository, but nothing changed. I will try to install an older kernel version to see if the issue disappear.

[Bas ON5HB]

Beware with the Fifo way....if the receiver.fifo isn't build with 'mkfifo receiver.fifo' it's not a fifo and it writes to disk.
As such the 'file' grows into TB's until your disk is filled.

When it's working as fifo, it's not growing, it's only a marker on the disk....but not actually storing samples/data.

[yo3ggx]

Is created with mkfifo, like recommended on this forum. Anyway, the error is the same when using pipe and is in rx888_stream, even if I run it with /dev/null

[Bas ON5HB]

Does dmesg say anything when the poll-error starts?

Also, have you stopped all other USB traffic to see if that helps?

I'm trying to help you here Dan, but it's hard.

Also, is your Stream-driver the latest? As there where some fixes, where output to STDOUT has been altered.

Show more info, as I can not see what you do...

[yo3ggx]

dmesg result is in my first post from today, there is nothing wrong from what I see.

Regarding if my Stream-driver the latest, rx888_stream is version 0.1.0.
You are talking about something else?

[Bas ON5HB]

Update last month:

https://github.com/rhgndf/rx888_stream/commit/b699542b8b8d31c64872bf1512c124537ae551f1

But did you run without the other stuff?

It helps if you answer questions.

Installed kernel  5.15.0-97-generic.
Redownload from git
run install.sh without any errors
Restore config toml and start script

Now is even worst, I get more errors when running start script:
