r2cloud native dependencies aren't compatible with Pi 4 (arm64)

[k7hak]

pi 4 fails with NESDR SMArt XTR (E4000) and rtl2838 pi 3 b+ both the dongles work fine tried to get more cpu with the 4 and it looks like its a no go both basic stacks with nothing else added. Same on usb3 ports vs usb2 ports.

Doesn't look like r2cloud related. r2cloud supports only single rtl-sdr dongle. 4 CPU cores used for:

1. Read the data from the stick using rtl_sdr program
2. Demodulate/decode at r2cloud
3. web ui
4. OS tasks

There was only a single dongle attached at a time, I swapped between them for troubleshooting reasons. I also don't believe its a problem with r2cloud but I feel that rp4 may be not compatible with rtl-sdrs at this time, I had a similar problem with the latest buster trying to get goestools to work as well. I totally dig r2cloud and was trying to gain some processing advantages from more ram and cpu cycles.

Got it. Yes, r2cloud depends on several natively-built applications. I can build and upload them for arm64.

I was able to successfully launch r2cloud on Pi4. No issues so far.
