ExistOS Dump Bridge for Linux

Forked from yuuki410/ExistOS-Dump-Brige

A Linux port of edb.

Flashing ExistOS firmware to HP39gII.

TODO

  • flash via USB MSC
  • flash via COM serial port no serial for you :D

Compiling

mkdir build
cmake -B build
cmake --build build

Flashing Firmware

edb -r -s -f OSLoader.sb 1408 b -f ExistOS.sys 1984

Known issues

If you use sbtool in conjunction with edb, for example loading OSLoader into calculator's RAM, there's a chance that the ExistOS disk cannot be mounted properly.

To circumvent this, put a battery into the compartment (if there isn't any), unplug & replug the USB cable, then try again. That should be it.
