Thanks!  It's working quite well for us actually.  We've released a 
firmware on one PCB and are having quite good luck with it.  SDCC does a 
good job with 8051 assembly.

What version are you using?  The lastest code checked into git doesn't 
include a parameter for that function.

Since you have the devel board, I made the most progress when I first 
started by enabling console IO on the serial port.  You can also use the 
light on/off functions when your firmware boots to help you figure out 
how far you're getting.

Do report back and feel free to comment on fx2lib function 
implementations if you find bugs or ways to improve.

Best wishes!
