I am using the button.c code, which accesses I/O pins and the two LEDS 
on th3 7260 board.  I cross compiled it and can run it as root on my 
TS-7260.  I have a web page with a button and form action code that 
invokes the binary executable.  The permisions on the executable are 
777, the permisions on /dev/mem are 777.
I can invoke a 'Hello World' executable just fine via the web page 
button.(FYI). The executable is in the cgi-bin directory.  The problem 
is the open("/dev/mem",O_RDWR) statement returns a -1.
What do I need to do to get this to work...

Thanks,
Steve
