DRV8308EVM: Closed loop speed control

Part Number: DRV8308EVM
Other Parts Discussed in Thread: DRV8308,

For close loop control, DRV8308 EVM GUI, section 3.2 Quick Guide to Spin With Speed Control was followed. The following problem was found

  1. In the instruction On All Registers tab, I am not able to select the SPDMODE bits to 00 (FREQ) Mode. When I set it to FREQ mode it sets to PWM mode by itself.
  2. The speed control is not working. The RPM does not remain consistent upon giving load. 
  3. The instruction provided in the last line of Section 3.1 was found untrue.

Please guide how can we operate the BLY171S-24-4000 (provided with EVM) in close loop control mode.
