Thank you.
I didn't cast the return value, so I'm geussing I misused printf.
I did "printf("%ld", call Counter.get());". I checked TestPrintfC.nc of
tutorial/Printf, and it uses %ld for uint32_t, so I assumed %ld is for uin32_t
format. Can anyone tell if I am using printf correctly?
Best Regards,
Rob

Who says it's negative?
When a signed integer's top bit gets set it "becomes" negative.
Somewhere along the way your unsigned variable is being mis-interpreted.
Often the default behavior is signed, so make sure you are using the
right declarations and casts.
Java doesn't know from unsigned, so the negative might be an artifact
of your tracing technique.
