RE: Dead HackRF
Hello Michael and all. I have obtained the CPU for the hack now, Michael, you graciously offered to repair it, and I would like to know where I should send the dead board and new micro? It does not power up and no LED's light up when plugged into the USB port. The micro gets very hot as well, I know it runs warm, but Hot? I've tried tracing out the path from the USB connector to determine if anything else may have died, but it seems to lead back to the microprocessor. Anyway, I would love to get this thing going again and would appreciate the help you can provide. Please advise Thanks!!

If the SPI flash chip is still in working order, then you may not need to do anything, it may just work. If not, then you'll need to use DFU mode as documented here: https://github.com/mossmann/hackrf/wiki/Updating-Firmware# [https://avatars1.githubusercontent.com/u/1195107?v=3&s=400]<https://github.com/mossmann/hackrf/wiki/Updating-Firmware#> Updating Firmware · mossmann/hackrf Wiki · GitHub<https://github.com/mossmann/hackrf/wiki/Updating-Firmware#> github.com HackRF devices ship with firmware on the SPI flash memory and with a bitstream programmed onto the CPLD. The firmware can be updated with nothing more than a USB ... only-if-necessary-dfu-boot, followed by a regular firmware update. > The Hack RF is still working with the Porta Pack, I can control it and it still does receive. > and my computers have a good earth connection now. If the PortaPack is still working then the microcontroller (LPC4320) is still working. There's a fair chance that all you've damaged is the USB ESD protection, which is designed to protect the microcontroller from this sort of thing. -------------- next part -------------- An HTML attachment was scrubbed...
