This was somewhat helpful information regarding your issue; and alludes to a basic computing concept you really need to understand in order to proceed!
It took some time for me to realize that you're serious. If you're unclear on what the 1024 error means, I'd suggest learning more about the number's significance in computing, especially if you're going to work with bootloaders.

Based on the conversation in Contacting page maintainer, I'm guessing that you've based that off a code commit from 2015. I'd advise following the instructions with an understanding of what you're doing in each step.
