- The author, Remy van Elst, updated a Linux port for the HP Prime G2 calculator, addressing keyboard mapping, touchscreen driver (Ilitek ILI211X), and larger RAM image size.
- The HP Prime G2 features an i.MX6 ARM Cortex A7 CPU, 256MB RAM, and 512MB storage, making it overpowered for a calculator.
- The port includes console login, X11 environment with xcalc, xeyes, xclock, Doom (prboom), and a C compiler (tcc) for on-device development.
- Running Linux on the G2 requires opening the calculator and shorting two pads on the PCB; the system runs in RAM and does not overwrite the original software.
