Garbage?

[scottbob09]

Been gone over a year. Came back. attempted RTFM installs on Pi4, 3, zero.
I had partial success on the 3B. Only to be dinked by having to run Bullseye.
c'mon man! On a zero, it should be flawless!

I have it working fine on Raspbian x64 Bookworm on a zero2. also works on pi4 and 3b+ with same image. There are still some distro-specific issues around 6.8 kernel and needing to remove "THIS_MODULE, " from smi_stream_dev.c and ensuring your user has rw access to /dev/smi and /dev/gpiomem so you don't need to use sudo for everything. Another note about the zero, you need an ethernet adapter, straight soapysdr remote connection over wifi is not usable for me, but ethernet works just fine. (I'm not running GUI on this one but am on others like pi4)

but, there is a stated and observed issue with bookworm you mentioned above. Bullseye works OK, but my other software doesn't.
What is the magic fix for SMI on Bookworm?

Before you run install.sh, nano carriboulite/driver/smi_stream_dev.c (going from memory, maybe its .../drivers/...) CTRL+W and search for: THIS_MODULE, (with the comma and a trailing space) and remove it from the line you land on so that there is just one parameter left within the ( ). That's the only extra work I had to do for it.

I also prefer to make the needed changes to config.txt, run apt update+upgrade, halt and install the hat before I begin install.sh. Then reboot once more and things should be functional.

I've run through this now on both 64-bit and 32-bit Raspbian Lite Bookworm, last night I performed the full steps on a pi zero (32-bit). aside from the painful compile times, the core issue on a non-2 pi zero is that its just too slow (cpu). I could not stream ANY amount of CS16 data using SoapySDRServer over a usb-ethernet adapter like I could using the zero 2. With the zero 2 (64-bit) I was able to stream the full 4msps/mhz over ethernet without any glitching. (wifi doesn't stream nicely in any case for me on 2.4ghz)

Hope this helps!

Side note, this is 6.6 kernel - NOT 6.8. I've not tried any OS with 6.8, only seen reports of it not working with the same steps as 6.6.

I use CubicSDR on the Linux PC side because its Soapy enumeration works the best in my experience, no need to understand or change the values, can just click Start and see IQ data flow.

So painful is the term I would use. I can get it to compile on a Pi. and its kinda usable, but not really. When I try to connect to it remotely, it just throws SMI errors. Which is par for the course. Never been able to use this device as easy as a usb dongle. whereas it should be easier. No good SDR apps for windows only complicates matters. Since they are all out dated, or specific to some program. It just isnt easy. You can plug in a RTL-USB and go to town. This is just too hard to use. Especially for Satnogs, etc
