This is a follow up to my previous post on how to run Debian on the Nspire, this time we will be going deeper into the matter and compiling the Linux Kernel ourselves, and doing such in a way that it’s compatible with Arch Linux ARM Hardware requirements The requirements for this project are the same as for the last one, here’s what you’ll need: A Texas TI Nspire CX or CX CAS USB Hub Mini-B OTG USB Cable USB Drive Setting everything up Since we will be building the Kernel ourselves this time we will need to do some special work on our setup, in particular to our build environment.

I’ve been taking a look at running Linux on ARM microprocessors, cross-compiling the Kernel from an x64 architecture and kernel tinkerings of the kind. After a bit of research I came across the information that my calculator, a Texas Instruments Nspire CX CAS, happens to use an ARM processor. With a clock of 150MHz on it’s CPU, 64MB of RAM and merely 100MB of flash memory I wasn’t sure Linux would run on this, but it turns out it’s possible .
