Other Parts Discussed in Thread: CODELOADER
I have successfully loaded the registers with CodeLoader software and RF output looks great with USBANY interface. Now, I tried to program SPI directly to the EVM pins with wires using standard LINUX SPI interface (the ZYNQ built-in SPI interface) but it does not seem to lock the PLL. I checked registers programmed and found I have written exactly the same things as CodeLoader's one analyzed by logic analyzer.
Here are what I have written. 10MHz ref, R=5, PD=2000, N=1250, K=0, channel divider by 2.
R5 (INIT) 0x40870010
As soon as registers were written, current changes from 37mA to 265mA. But the LD LED does not lit. I think I am missing one small step. Can you check what is going on?
