I Got an IP Address
I'm sick of complex blogging solutions, so markdown files in a git repo it is - francisrstokes/githublog
We're going to cover a little bit of that in this article - primarily how I was able to use DHCP to obtain an IP address from my home network, but also how the overall architecture of the firmware is laid out, and of course how I build some tooling to help debug the whole process. For the sake of brevity, I won't go into the full details now, but it involves sending a unicast DHCPREQUEST directly to the server - this time filling out the ciaddr field. This post (and of course the work itself) has a fairly different character to the previous one; Fewer soldering irons and timing issues, more "high level" firmware considerations, and understanding layers of the stack.
