I have a problem I downloaded evaluation version of ARM and 51 development kit and installed both of them.But As I open any 51 project included, I can't compile for 51 microcontrollers. Toolchain path is still seen as set for ARM\bin. When changing form menus, I can success at this. But I want to set up tool.ini file OR how can we set this automotically recognition by Keil when I want to open project from 51 or form ARM project?
"If the uv3 app that is installed with the ARM compiler is started, then it will only find a tools.ini file without any mention of any C51 applications or settings."
Absolutely - and, conversely, the C51 installation won't know anything about the ARM...
