I am trying to connect HMC8336LP6GE evaluation board but I consistently receive "lost communication" message at GUI.
My procedure is as follows.
- Connect RF board, USB interface board and computer;
- Open evaluation software, select HMC833 from drop down menu;
- Apply power 5.5V to the RF board, then current level is around 207mA.
- load register file(hmc833_int.txt or hmc833_frac_fb.txt) ; but connection is lost and all registers are read as "FFFFF".
What causes this problem? Any comment will do.
