Hi All,
We run into an issue when use e500mc toolchain g++ to compile c++ code for
p2020 platform, the code as below:
main.c
#include <iostream>using namespace std;
int main(void) { cout << "asdfasdfasdfasdf";
return 0;}
compile it with command "powerpc-fls-linux-g++ main.c" and the output file's
name is a.out, download the binary to p2020rdb board, but the console prints
the error log "Illegal instruction".
It is all right on p2041 platform.
The version of toolchian:

Is e500mc family downward compitible with e500v2? C code can run correctly on
p2020 with the e500mc toolchain.
Thanks & Best RegardsJiucheng
