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.

Below is a link to my annotated disassembly, BUT there is a good chance that this link is out of date, you really should go to the repository on Github where you will find the latest work.

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.
