edy555 release 0.7.0-20200223-white screen

Mike N2MS All Messages By This Member #11402 Herb and All, I followed your instructions and upgraded my NanoVNA-H form a Hugen-H firmware to version 0.7.0-20200223 followed by a reset and clear 1234. I tired the calibration routine but did not get inconsistent results so I tried to install the Hugen firmware but I erroneously installed Hugen-H4 firmware in by HanoVNA-H unit. Oops! When I tried to exit the DFU mode via a power reset I get a white screen upon powerup. I powered down and tried to get back into the DFU mode by shorting the P! pins but the DFU mode does not reappear nor do I see a com port connection via the Device Manager. It looks like I hosed my unit. How and I re-establesh communications to my NanaVNA-H? By the way, the inconsistent results I get after the calibration routine is that a short is displayed as 50 ohms on the Smith Chart.

The edy555 0.7.0 release is located at . It's inside the nanovna-firmware-0.7.0.zip archive. Unlike most other developer's edy555 does not include a .dfu binary in his releases. Seasoned users know that you have to convert the hex binary in the archive to dfu format to flash it to the NanoVNA on Windows. It's an extra step that discourages some new users.

Mike N2MS All Messages By This Member #11404 Larry Success. I powered down the unit for a couple of minutes and tried the short across the P1 boot pins. This time it was successful. DfuSE Demo recognized it and I was able to successfully load the Hugen-H firmware. I would still like to check out the edy555 release 0.7.0-20200223. Has anyone had issues after running the calibration?

Larry Rothman All Messages By This Member #11405 GREAT !! I have it installed and I had no issues after the default (50K to 900M) calibration. Remember to press the onscreen RESET button just prior to running a calibration on the unit. You can save the cal to any location 0 through 4 .That will allow you to compare a few cal runs against each other. Location 0 is the power-on default. Use that if you play with a specific freq band. Just remember, the default firmware only grabs 101 cal samples, spread out over the freq span - and interpolates between them, which can be problematic. Use the NanovnaSaver PC app to cal and scan as many points as you want for a given freq span.
