Call me timid, or call me paranoid, but I wanted to make a copy of the firmware that's already in my Plus before I erased it and re-flashed it with something new.
I'm running Windows 7. I have FLIP installed and working, connected to the Printrboard. There's a button on there to "Read" the board's memory, but when I click it, I get a message "Device Protection is Set." So what does this mean? I googled it and they are talking about locking bits that might be set in the software. Is there any work-around? Why would Printrbot have had the locking bits set? Will the locking bits interfere when I try to reprogram? In the google info that I found, it talked about the possibility of erasing the DFU bootloader.
Is it that the bootloader resides in a particular part of memory, and it's protected? Should I be trying to Read a subset of the entire memory to avoid the bootloader?
When programming with a new version of Marlin, is the bootloader automatically included in the rewrite of memory, or is it somehow in a "safe" zone that doesn't get touched?
(Eventually, I will publish a log of how to do this under Windows 7. So far, everything has resembled what I see in the instructions, but always just a little different and just a little harder.)
