Hello Hein,

although this is of course not the right thread to ask this question, I’d like to comment on the
file latest Zynq_Zybo_driver.zip, which you attached to your last post.
Only 2 files are different to my actual NetworkInterface-files. And when I exchange the file NetworkInterface.c the transmit speed slows down from 720 Mbit/s to 44 Mbit/s.

Is this due to the call of the function ulReadMDIO( PHY_REG_01_BMSR ) ?

For the time being I stay with the previous file from: June 05, 2017, 4:02:15 AM

Best regards
