AD9361 No-os, ad9361_txrx_synth_cp_calib

I am currently having trouble getting the development board to carry out the calibration on CP correctly. 

 

Looking on the scope at the returned data byte when asking if CP cal done, it is never getting set.

The code follows the entire Non-os ad9361.c etc. and will not calibrate once reaching the Rx/Tx part.

This is using the AD-FMCOMMS4-EBZ.

In terms of set-up, it will be using the on board crystal and I have used the product along with a Zed board and the Scope program works OK.

I have set-up to the DEV board:
PG_FMC 3.3V
3.3V to board
2.5V to board
0V

RESETB
SPIMO
SPIMI
SPICLK
SPI_ENB
VADJ 2.5V

Is there anything I am missing?  What would not cause the calibration to be carried out?

 

Thanks

 

Best wishes

Andrew
