Re: Any update on em28xx on igevp2 ?

Hi Devin,

just some extra info:

I have tested the difference on the arm board compared to the pc:
  int  height=576;
  height >>= 576;
  printf("%d\n", height);

on arm it gives a 0, on the pc it gives 576.
on both i get a warning from the compiler, as in my test code the 576 is 
hardcoded in stead of a variable
warning: right shift count >= width of type ( which is logical ;) )

regards,
Gert-Jan
