Rip'Em is a 3rd party firmware for the HP Prime calculator.
As always : please void your warranty in a responsible manner. I will decline any responsibility should you turn your HP Prime into the thinnest CAS calculator brick available currently on the market.
On Debian and Debian-like systems :
- Install the ARM cross-compiler toolchain (
apt-get install binutils-arm-none-eabi gcc-arm-none-eabi gdb-arm-none-eabi) ; - Install support packages (
apt-get install build-essential libelf1 libelf-dev) ; - Run
makeinside the top-level directory.
Everything else : you are on your own.
Using the HP Connectivity Kit :
- Replace
PRIME_OS.ROMwith the filebin/ripem/PRIME_OS.ROMgenerated when building Rip'Em ; - Flash the new firmware.
Everything else : you are on your own.
A graphical menu is shown to select a payload to run.
These payloads are currently available :
- dumbcalc.elf : a dumb integer RPN calculator, as a concrete demo ;
- dummy.elf : a dummy payload to showcase functionality ;
- gdbstub_serial.elf : a bare-bones GDB stub over the UART.
