Atmel Studio 7 came with a new version of the firmware for its JTAGICE3 debugger. The current version installed on our hardware is 3.25. The new version is 3.2a.
We can't use the debugger without upgrading, but the firmware upgrade fails. The specific message given is as follows: "JTAGICE3 firmware upgrade failed, toggle power on tool and retry upgrade"
Of course, there is no way to toggle the power on the JTAGICE3 programmer except to unplug the USB and plug it back in. That has no impact. I've tried upgrading the firmware on two different devices, and both failed multiple times with the same error message.
