Upgrading my old Chumby 8 Linux kernel part 1: U-Boot

With that initial explanation out of the way, in 2022 I’ve been getting my Chumby working with the mainline Linux kernel and slowly trying to submit fixes upstream for issues as I find them. To be clear, I’m not trying to get the stock Chumby software working with the new kernel. That’s likely impossible. The stock software is heavily dependent on Flash which is a dead end. I’m just getting the new kernel running well enough so that I can develop my own custom software for it. I’m going to write a few posts about that process and some of the fun challenges I had to overcome. This first post in the series will talk about some of the work I did with U-Boot.

If you’re into Linux kernel development, there’s massive number of devices out there running outdated kernels you could be updating for fun, in your spare time.
