Hello! I'm trying to compile for Texas Instruments (TI) C6000 Digital Signal Processor (DSP) using GCC. I'm aware that TI has its own compiler, but I want to use GCC.
The documentation indicates that GCC has *some* support for C6x DSPs, as shown in this link: https://gcc.gnu.org/onlinedocs/gcc/C6X-Options.html However, when I run a simple command like gcc -c main.c -march=c674x -I/include -Tlinker.ld, it fails with this error: main.c:1:0: error: bad value (c674x) for -mtune= switch. I've read on forums that GCC 4.7 has *some* level of support for C6X DSPs, but even after installing GCC 4.7.4, it still doesn't work. Some forums also mentioned a GCC-based toolchain developed by CodeSourcery (later acquired by Mentor Graphics, and subsequently by Siemens EDA) that supported C6x DSPs. However, it's no longer available; I can't seem to find any download links online. Could someone please advise on which GCC version is compatible with C6X DSPs? Any guidance would be greatly appreciated. Thanks in advance!
