Ask for help about fsl ppc toolchian issue "Illegal instruction"

[许久成]

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
