| // This file just contains this one symbol, used by the reset code. |
| // It is here rather than in reset-vector.S because we want the symbol |
| // to be external, so resolution is delayed until link time. |
| // |
| // To define your own value to override this default, redefine the |
| // symbol _MemErrorHandler to the desired value, e.g. - |
| // |
| // xt-xcc test.c -g -o test -Wl,--defsym=_MemErrorHandler=0x08080808 |
