The ESP8266 bootrom

It is easy enough to read out the binary image of the ESP8266 bootrom. I spent some time disassembling it and then tidying up the disassembly. Once I was reasonably satisfied with what I could accomplish with automated scripts, I sat down to study and annotate the result and you can find that here.

Other work

In January of 2017, I received an email from Paul Sokolovsky telling me about work done by him on the ESP8266 bootrom. Apparently Paul is "pfalcon" on Github.
