Never compile on the target ! GNU Radio on embedded systems using Buildroot
summary
This covers porting GNU Radio to embedded boards by cross-compiling with Buildroot so users avoid compiling on the target device; specifically they cross-compile GNU Radio for Raspberry Pi 4. It shows a course project that pairs an RTL‑SDR DVB‑T dongle as receiver with PiFM (using the Pi4 PLL) as an FM-band signal source to build a low-cost embedded RF network analyzer for students working remotely.
