Hi people, I have compiled the file Blinky.c of the example of Keil with inline assembly, with options "Generate assembler src file" and "Assemble src file" checked. I have achieved the seguent result: Linking: Warning: L1 Unresolved external symbol. Symbol: ?C_startup Module: Blinky.obj (Blinky) 0 Error(s), 1 Warning(s). Does anyone tell me where I have wrong? Best regard. Antonello
