So anyone wanting to develop or modify the SM3000 would need to install two pieces of proprietary software with considerable strings attached? Those being Vivado and Altium. This is unfortunate for an otherwise libre project. Especially since KiCAD, yosys and nextpnr exist. > What I want to achieve is a instant on, plug and play solution with > digital radio /front panel upgrade path. > > In the spirit of the SM1000.

Both boot time and SD card issues should be possible to mitigate by picking a more appropriate distro than NOOBS, and appropriate boot flags (-o ro). The real problems with the Pi is the blobs and the NDAs. That's all the feedback I had for now. /Tomas _______________________________________________ Freetel-codec2 mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freetel-codec2
