The LEON3 BSP has been using mcpu=cypress which is a SPARCV7 that is compatible with SPARCv8 CPUs. This patch enables the relatively new LEON3 model and generates SPARCv7 compatible code. This shuold be comptabile with all single-core LEON3/4 systems. The LEON3 model is required for SMP to make GCC generate the CAS instruction. --- c/src/lib/libbsp/sparc/leon3/make/custom/leon3.cfg | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
