Ghidra STM8 processor module
just copy files to
$(GHIDRA_HOME)\Ghidra\Extensions\
In this case you also build an analyzer plugin that automatically assigns the proper calling convention. This is very useful for big binaries.
- run
# GHIDRA_INSTALL_DIR=$(full path to ghidra installation) gradle - open Ghidra
- in the project selection window click File -> Install Extension
- select
lib/ghidra_STM8.jarthat was built by gradle
STM8 uses two kinds of pointers: standard 16-bit, that can deal with RAM, I/O area and the bottom of Flash and 'far' 24-bit pointers that can address all memory.
In Ghidra far pointers can be declared as byte *24, my_struct *24, etc.
Functions that called by CALLF should be declared as __farcall. Standard ones, that called by CALL, should be declared as __stdcall (default behavior).
If the flash image is larger than 32 kbytes, use STM8:BE:24 language, otherwise either option can be used (but STM8:BE:16 gives clearer output).
