Yeah it does. But the install does a recompile.

It's not always easy. You are not the first that saw this.

Happened to all of us ;D

I got OpenCL going and it sees the Intel uhd graphics now! :-)
How do I easily rebuild this install so it sees openCL?
I tried just running install.sh again, but obviously that's not doing it. (my apologies, I'm still learning Linux)

Ok - so I have to figure out how to run OpenCL on this thing.  It shows the graphics card as a "Intel Corp WhiskeyLake-U GT2 [UHD Graphics 620].  Hopefully I can dig up a driver.

When you see Cypress Semi Corp RX888 it's running with Firmware loaded.

Looks to me the spectrumserver is failing to start/read samples.

When you set acc to none, it means the CPU has to do all, this will not work at 30MHz...
Upto 10Mhz or so, but forget 30MHz, even a Ryzen can't handle it.

You need OpenCL running.

Ok - so I got the old Dell running like a champ.  I figured I would push my luck and try to get one of my RX888's (v1) running on the newer Dell Latitude.  In the config, I set it to accelerator = "none" since clinfo doesn't list any devices.
It looks like it's running, but the waterfall is blank and audio is silent.  I see rx888_stream running but not using any CPU at all.  Is the firmware for the RX888 mkII ok to be used on the original RX888?  (BTW, I can feel it getting warm - so it's running!).  lsusb shows it as "Cypress Semiconductor Corp RX888" so it's definitely not in DFU mode.

Edit: I swapped in the RX888 mkII - no change.  So it's not the device.

Quote from: K3FEF on 13 Oct 2025, 15:10 I have a dell Latitude w/ a 8th gen i5-8265U (w/ Intel UHD graphics 620) and 8GB ram.  Think that might be a good candidate? :-).

Normally yes.

fft_size = 131072 => too small 8388608
audio_sps = 20000 => wrong MUST BE 12000 else FT8 won't work, also 12000 is plenty
waterfall_size = 1024 => 2048 zooms better ;)

You could try putting threads at 2 for fft, but as you use GPU, it may not do anything.

Shopping for a different GPU won't do much, better switch to Intel gen6 (or newer CPU) with build-in GPU.

I use and HP Elitedesk refurbed with 8GB ram....old CPU but more then enough: Intel(R) Core(TM) i5-7500 CPU

The thing is, the internal GPU is very well supported by Intel for GPU use and capable of doing 50MHz bandwidth, we tested. However the USB-bus craps out for 1 receiver ;D

The settings you use are for small bandwitdh, the CPU and GPU will do more with mine.
