I just had to restart some things, and it has cost me half an hour to get things to work again....
I searched for a compatible VESC_TOOL because all of them said: The attached vesc is too old, please upgrade with a programmer. I may have a "slightly older" vesc6, and I don't currently want to risk bricking it by trying (and failing) to upgrade the firmware....
Anyway... it turns out that I had found the right VESC_TOOL, but when I select the right TTYACM and then click the big "connect" button, it keeps reporting too old, upgrade using programmer. Turns out that the big button I was clicking is the "connect to last device" button, and not the "the currently selected".
* Disable the big connect button when on the "connection" tab.
* make the big connect button connect to whatever is selected in the connection tab. (and remove the button on the connetion tab).
The message is also confiusing: I have another project that happens to be connected and that too uses CHIBIOS virtual com port.... What do I have to implement to make vesc_tool say: "The attached devices says it's not a VESC"? :-)
