[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

Hi everyone.
My hackrf one suddenly stopped working.
When I try rx (or tx) I don't receive any samples and hackrf stops
responding/ all 6 LED are on.
Flashing different firmware doesn't help (using DFU as well).
Same on different computers and different cables.
The md5 of firmware from the device matches the .bin file.
$ hackrf_info
hackrf_info version: git-90d3f7f
libhackrf version: git-90d3f7f (0.5)
Found HackRF
Index: 0
Serial number: 000000000000000014d463dc2fa077e1

Couldn't transfer any bytes for one second.

$ hackrf_info

hackrf_board_id_read() failed: Input/Output Error (-1000)
Looks like a hardware failure?
Thanks in advance for any suggestions/assistance

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

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

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 (for about 14 hours).
Could that have something to do with it?

Also I remember I heard some high freq noise from the hackrf (after running
hackrf_transfer) when I first discovered it was broken.

Thanks,
Andrew

Andrew,

Was that audible noise from the hardware itself (not the attached USB
host)?

Thanks,

Mike

Hi Michael,

Yep from the hackrf itself.

Thanks,

Yes, that definitely sounds like a hardware failure in a voltage
regulator. We'll replace your HackRF.
