[Michalych1974]

Good day. Question about the firmware: what is this firmware for (circled in red)? What will happen if you try to load it?

More information required to answer, if an answer is possible. Or to make the question interesting to people that may know.

What is "the firmware"? Where is that directory structure containing the red circle? Firmware for what device? Where and how will you load it?(port, protocol, file format) What CAN bus?
