We bought an ADuC7020 QuickStart system. GNU Compiler translates C++ programs successfully, but uVision3 hangs when trying to download an executable file into the chip (through Keil ULINK). Whereas C-programs download normally. uVision3 hangs even when downloading such simplest program: struct A { virtual void f()=0; }; struct B : public A { virtual void f(){} }; int main() { B b; A* a = &b; a->f(); return 0; } Thanks. Dr. Tychinsky.
