Re: how to booting the redboot on VMware


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!!
