endrazine / binutils-tricore Goto Github PK

Hello,

I built from sources (provided by HighTec to avoid GPL violations here https://www.hightec-rt.com/en/downloads/sources.html) the binutils 2.13 package targetting the tricore architecture with host Windows under x86 (686) platforms. Sources files are provided on this repository if needed (in case where the URL link will be not available).

As the tricore arch is not an official branch of gcc/binutils, there is no package found with free of charge…. So I prefer to build it as Hightec made sources available.

It could help to read the content of elf files, PFLASH dumps in S-Record formats or bin file (to see opcode, jump table…) on projects using Infineon Tricore CPUs taken in charge by changes made by Hightec, at this date.

The Mingw32 gcc toolchain revision 4.8 have been used to build sources. Windows executables files can also be running under linux using wine by example. Binaries files have been linked statically using the gcc runtime file libgcc.a. No need to provide libgcc_s_dw2-1.dll file (GPL).

The details with examples using somes commands lines, using an elf file built targetting a TC1797 CPU:
