FYI: The firmware status has improved significantly, It is now 'fully functional' in that it can tune, receive and stream digital spectrum via USB high-speed isochronuos transfers into a PC, where alsa happily receives them even at speeds in the range of 1MS/s. In contrast to earlier versions, SSC/DMA start and stop is now fully automatic with opening/closing the audio device on the USB host (Linux PC). Tuning cnanot yet be done via USB but has to be done on the UART. Commands like and can be used interactively on a mini embedded command line. For some more info on usage, check https://sdr.osmocom.org/trac/wiki/GettingStarted The RF guys should now be able to validate that the spectrum of the device is clean and thus authorize the production of the first batch of 100 units. With some luck, they will be available at OsmoDevCon !
