because I need to pass this array to a function
but i get warnings that says "initialization makes pointer from integer without a cast " and "assigments makes integer from pointer without a cast"

Yes, that is an array if pointers, that you initialize with the integer value 0x61626364, etc - and the compiler thinks "well, that's an integer, assigned to a pointer - I wonder if that's what the author wanted? I'd better issue a warning.".

If I declare the array like this

Code:

unsigned long data[3] = {0x61626364, 0x65800000, 0x00000000 }

I then I pass tu my function like this

Code:

func(&data[0])

I get an error that says that memory 0x... couldnot be written

I need some help, anybody?

What does "func" do?
&data[0] should give you the address of data. But func(data) should work just fine too.
