All,
It's alive! (Apologies to the original Frankenstein movie)
Here is a summary of what happened, what I'll suggest Johan consider, and what my next steps are.
First, thanks again to Johan and Ram for their help. Launching a project like this into the wild is hard, and there is always a support tail.
I bought a new RPi4 from Canakit and a radioberry board from a Chinese source. I used the recommended Raspian OS (32 bit) using the imager software. It loaded gcc-10.2.1 and installed Johan's install script with errors, but still claimed success. This process was consistent across multiple installations of the software. The command "sudo radioberry" returned that 'radioberry' was not found.
The initial issue was pihpsdr did not find the radioberry, and neither did sparkSDR. After a detailed look at the output of the installation script, both fatal errors and warnings were noted, leading to the conclusion that there was an upgrade in the RPi distribution, specifically, the C compiler.
Work was done to remove the fatal errors (thanks Johan!) but the warnings remained and while the radioberry was now found by software, there was no signal detected.
I then removed gcc-10 and installed gcc-9, and though 'gcc --version' did not return correctly, the install script ran without error or warning and now the device works.
Luckily, there was no need to threaten the radioberry with my heat gun to reflow under the chips.
I would like to suggest the install script be updated for gcc-10. At this time, any new RPi OS install will install gcc-10 and so break for any new folks. I'm happy to be a beta tester.
My next steps are first, continue to dig into pihpsdr software to understand what I can do with it and second, hunt down a preamp board and or the juice board. The goal is to build a portable qrp rig.
Thoughts and suggestions happily accepted.
73, and Happy New Year,
Pete
