Why 'volatile'? Also, there shouldn't be an empty line before it but there should be one after it...

I used a volatile to prevent the compiler from optimizing out the (normally) useless loop. Is there a cleaner way to do this?

If the board supports udelay(), you should use that instead of a loop.

Best regards, Alex

Amicalement,
