I used an no upstream toolchain to verify coredump backtrace, which use the EM_CSKY_OLD equals to 39. We have changed the EM number to 252 in our newly released toolchain with compatibility to EM_CSKY_OLD. See binutils/include/elf/common.h: /* C-SKY historically used 39, the same value as MCORE, from which the architecture was derived. */ #define EM_CSKY_OLD EM_MCORE Thanks, Mao Han
