Re: [Hackrf-dev] Broken hackrf one

Yes, that definitely sounds like a hardware failure in a voltage regulator. We'll replace your HackRF. On Fri, May 25, 2018 at 12:25:12AM -0500, Andrew Onyshchuk wrote: > > Hi Michael, > > Yep from the hackrf itself. > > Thanks, > Andrew > On Fri, May 25, 2018 at 12:17 AM Michael Ossmann

Hi Michael, Yep from the hackrf itself. Thanks, Andrew On Fri, May 25, 2018 at 12:17 AM Michael Ossmann wrote: > Andrew, > Was that audible noise from the hardware itself (not the attached USB > host)? > Thanks, > Mike > On Thu, May 24, 2018 at 11:45:38PM -0500, Andrew

Andrew, Was that audible noise from the hardware itself (not the attached USB host)? Thanks, Mike On Thu, May 24, 2018 at 11:45:38PM -0500, Andrew Onyshchuk wrote: > > Dominic, > > Not after firmware update - I was using the same firmware (some git master > from 6 months ago) for some time.

Re: [Hackrf-dev] Broken hackrf one

Dominic, Not after firmware update - I was using the same firmware (some git master from 6 months ago) for some time. 2018.01.1 is the result of trying different firmwares after it got broken. I think(not sure though) I left hackrf connected(but not in rx/tx mode) to my macbook air on that night

Re: [Hackrf-dev] Broken hackrf one

Hi Andrew, It certainly sounds like something os going wrong on the board itself. Did this start happening after you upgraded your firmware to 2018.01.1? How are you powering the device? From a laptop/desktop computer? Thanks, Dominic On 24 May 2018 at 20:33, Andrew Onyshchuk

Re: [Hackrf-dev] Broken hackrf one

Hi Dominic, It becomes unresponsive only after I try using hackrf_transfer. After that it is completely unresponsive and only rebooting/reconnecting helps. I'm guessing the ARM chip crashes or turns off. Maybe power supply issue? Thanks, Andrew On Thu, May 24, 2018 at 7:31 PM Dominic Spill

Re: [Hackrf-dev] Broken hackrf one

Hi Andrew, Is the HackRF permanently in this state? Or does it switch from responding to hackrf_info to not responding only after you try using hackrf_transfer? Thanks, Dominic On 21 May 2018 at 16:43, Andrew Onyshchuk wrote: > Hi everyone. > > My hackrf one suddenly

Re: [Hackrf-dev] Broken hackrf one after firmware update.

You should also update the CPLD: https://github.com/mossmann/hackrf/wiki/Updating-Firmware With new firmware and old CPLD I would expect the spectrum to be inverted in some cases. A fixed frequency offset would be puzzling unless it is a misinterpretation of inverted spectrum (which could be an
