[Hackrf-dev] Hackrf firmware upgrade issues

[Paul Michelle]

Thanks for the reply Dominic.Firmware version reported after DFU was 2015.07.2. Also tried it with version 2015.07.1 suspecting it was a corrupt firmware download. I also uploaded from hackrf while in DFU mode and tried to compare the file size; they did not match (not sure if it should have, wrote 19.8kB file and read 131.1kB file)Clarification: in DFU mode I'm writing to flash from USB, giving me a recover method to use spiflash and write a ROM image to Flash; is that correct.
It's a new unit (week old) might request a RMA.
Thanks for the assistance.AJ
