Re: [Fx2lib-devel] possible bug in setupdat.c

[Dennis M. <de...@ub...>]

It is a bug.   It should be:

 __critical { 
     printf ( "Hi Speed or reset Interrupt\n" );
     if (highspeed) {
         pDevConfig=(WORD)&highspd_dscr;
         pOtherConfig=(WORD)&fullspd_dscr;
     } else {
        pDevConfig=(WORD)&fullspd_dscr;
        pOtherConfig=(WORD)&highspd_dscr;
     }
 }


When the device is in full speed mode, the pOtherConfig should point to 
the the highspd_dscr, which is the default POR mode.
Currently, my device doesn't support full speed mode (It's on my list) 
so I hadn't caught that issue yet.
