[Hackrf-dev] DFU

[Graham Cottew]

With the hackrf_usb.dfu file you sent me and dfu-utils v 0.7 I can do a DFU that appears OK

The Jawbreaker is then found by hackrf_info and works fine with gnuradio on Tx and Rx
VCCLED, 1V8LED and LED1 are all on when it is idle

Problem is when I power cycle the board the DFU firmware just disappears and I am left with 
VCCLED on
1V8LED off
LED1, LED2, LED3, USB_LED0, USB_LED1 all dimly lit

Can you suggest what I can do to overcome needing to DFU every time I use the Jawbreaker?

DFU:

$ sudo dfu-util --device 1fc9:000c --alt 0 --download hackrf_usb.dfu
