Documentation/Platforms/TriCore

Introduction

TriCore is a unified, 32-bit microcontroller-DSP architecture optimized for real-time embedded systems. It mostly targets gasoline and diesel engine control units (ECUs), applications in hybrid and electric vehicles as well as transmission, active and passive safety and chassis applications. The instruction set architecture (ISA) consists of three types of instruction sets: one microcontroller, one RISC load-store, and one DSP instruction set -- thus the name TriCore.

Build Directions

 ./configure --target-list=tricore-softmmu && make

Running a binary

 qemu-system-tricore -M tricore_testboard -kernel /path/to/your/binary 

Please note that there is no real existing TriCore board implemented so far. The suggested testboard only instantiates memory and a CPU, and thus no I/O is possible.

Attaching gdb

If you use gcc to build your guest binary, make sure you build using the old debug symbols. The flags for gcc are

 -gdwarf-2 -gstrict-dwarf

Now you can start QEMU

 qemu-system-tricore -M tricore_testboard -kernel /path/to/your/binary -s -S

QEMU will halt until you attach with the tricore-gdb

 (gdb) target remote localhost:1234
