Subject: [PATCH 0/6] TriCore Semihosting
Date: Sun, 15 Oct 2023 22:59:07 +0200	[thread overview]
Message-ID: <20231015205913.264782-1-kbastian@mail.uni-paderborn.de> (raw)

Hi,

this patch series implements semihosting as done in the golden Infineon
simulator 'TSIM'. 'TSIM' supports different semihosting variants, specific to
various toolchain vendors. Only the GNU toolchain with Newlib [1] is freely
available, thus I only implemented semihosting for GNU. This port of Newlib is
also available in the 'debian-tricore-cross.docker' image.

To build and run a binary with semihosting, one only has to link against libos, i.e.

tricore-gcc test.c -los -o test.elf
qemu-system-tricore -M tricore_testboard -semihosting -nographic -kernel test.elf

Cheers,
Bastian
