Part Number: AFE7950EVM
Other Parts Discussed in Thread: AFE7900, LMK04828
- I have pasted LMKProgram.py program. My issue will be written in next point.(Note: LMK is getting programmed and I am getting qpll acknowledgement)
- I am trying to program Afe but i am getting follwoing errors (AFE is not getting programmed)
