Here’s the VisualGDB diagnostic output from 5.4 R12, same USB port, etc… that I had used with 5.5 R4 (and that log as above)

Yes, I’ve been trying different things; different machines, different USB ports, etc…

The arduino tools all work as expected.  VisualGDB 5.5R4 fails in all cases.

I was positive this used to work back when I purchased my VisualGDB license (but I’ve since built a new machine, etc…).  Then I noticed that VisualGDB had an update posted on december 3rd, 2020.  So I uninstalled that version and moved back to the one I likely was using… 5.4R12.  And now VisualGDB flashes successfully.

Thus I presume there’s a software regression somewhere in the latest version of VisualGDB?

Discovered that arduino has a web editor.  Uploading a sketch from it displays more information in it than the arduino IDE.  Attaching that info.

Device manager does show a swapping of ports when uploading the sketch from the Arduino IDE.  Today was COM13 -> COM14 (bootloader) -> COM13.

When flashing from within Visual GDB that does not occur.

How do we fix this?  (I’ve got 4 different boards and VisualGDB fails to flash any of them–currently regretting my purchase of VisualGDB)
