-====== Radio programming ======
-The Radio dongle can be programmed either via USB bootloader or via SPI. The USB bootloader does not require any hardware but is **not** currently (as of 2012-09) full-proof (if the flash procedure does not complete well the dongle will have to be reprogrammed via spi). It is recommended to program only released firmware via USB.
-In Linux it might be required to launch the commands accessing the USB port as root (ie. with ''sudo'')
-===== USB bootloader (command line instructions) =====
-First Crazyradio has to be rebooted in USB bootloader mode. To do so insert the dongle in the pc, open a terminal window and run the bootloader launcher:
-<code>
-> cd crazyradio-firmware
-> python usbtools/launchBootloader.py
-Launch bootloader .
-Bootloader started
-</code>
-After running this tool the Crazyradio dongle should have disappeared and a new device named ''nRF24LU1P-F32 BOOT LDR'' should appear.
-To flash the firmware use the nrfbootload.py script:
-<code>
-> cd crazyradio-firmware
-> python usbtools/nrfbootload.py flash firmware/bin/cradio.bin
-Found nRF24LU1 bootloader version 18.0
-Flashing:
-  Flashing 5771 bytes...
-Flashing done!
-Verifying:
-  Reading firmware/bin/cradio.bin...
-  Reading 5771 bytes from the flash...
-Verification succeded!
-</code>
