I use uVision 1.31/C166 on WinXP computer. It was working well but now I've got a problem. When I click Build All there are Compiling messages in Project Status window but compilation seems very fast. Building ends with 'HEX File Not Created' message. There are no error messages. It occurs that the files are not compiled and the .log file is empty. Obj files have old date. I've tried to reinstall uVision but the problem still exists. Have anybody met with such a problem?
