Does the alt_u16 type support 0xFFFF or not?

Please consider the following code: ... alt_u16 i; .... for(i=0x0000; i<=0xFFFF; i++) ... I am getting the following warning during my compilation: comparison is always true due...

alt_u16 can hold 0xFFFF, but it can't hold anything larger than that. So the comparison "<= 0xFFFF" is always true. Which is exactly what the compiler is telling you the problem with your code is.

You can use an alt_u32 to keep the rest of your for() loop the same as already written.
