I dont understand what I need to change to fix this ? I am using the toolchain installed from this:

Why open and close? Please specify what you did to solve your problem so others can find out. Was it an old version of esptool?

[jonshouse1]

I was being dumb, I failed to read the notes and put the absolute path of esptool into the FW_TOOL field in the makefile rather than building the required esptool utility and referencing it. Basically I got confused as the two utilities have the same name.

I've improved the way this works anyway. You should give it a shot now.
