Thank you for your anwser. Maybe I will ask a silly question. In a normal C program, the execution of the program start from the beginning of the main function. In the folder "\packages\kernel\v2_0\tests" i saw there are some test files. ( I don't know if all these files can be used as individual application examples ?). In these files, I can not see the main( ) functions. They only have cyg_start( ). So I am confused where the application program start from, if they have no main( ) functions. And who invoke the cyg_start( )function?
Can you help me with these questions? Thank you so much!! On 5/23/07, jiang jet <[EMAIL PROTECTED]> wrote:
