I am trying to read the statistic registers from the ixf440, so far no success. I went through your example codes. In the control.c file ( libixprouter.tar ) i saw that you use the scratchRead32( ) function to do the job. I could not find this function. Can you advise me on this matter? You my find this Q too obvious, but i am a beginner on the system, anything is helpful to me. thanks Tomer.
