We Fixed the Glitch Posted at: They'd had to stop production because units coming off the line were failing at a high rate. This was quite a surprise because HackRF One is a mature product that has been manufactured regularly for a few years.
I continued to find surprises as I went through the process of troubleshooting the problem, and I thought it made a fascinating tale that would be worth sharing. The reported failure was an inability to write firmware to the flash memory on the board.
Our attention quickly turned to the flash chip itself because it was the one thing that had changed since the previous production.
The original flash chip in the design had been discontinued, so we had selected a replacement from the same manufacturer. Although we had been careful to test the new chip prior to production, it seemed that somehow the change had resulted in a high failure rate.
Had we overlooked a failure mode because we had tested too small a quantity of the new flash chips? Had the sample parts we tested been different than the parts used in the production? We quickly ordered parts from multiple sources and had our contract manufacturer send us some of their parts and new boards for testing.
We began testing parts as soon as they arrived at our lab, but even after days of testing samples from various sources we were unable to reproduce the failures reported by the contract manufacturer.
This failure happened regardless of which flash chip was used, and it was easy to work around by retrying. If it happened on the production line it probably wouldn't even be noticed because it was indistinguishable from a simple user error such as a poor cable connection or a missed button press.
Eventually I determined that this low probability failure mode was something that affected older boards as well. It is something we might be able to fixbut it is a low priority.Dear Twitpic Community - thank you for all the wonderful photos you have taken over the years.
