CC1120-CC1190EM915RD: Controlling my CC1120+CC190 using RFStudio

Part Number: CC1120-CC1190EM915RD

Hello,

I have designed a CC1120 + CC190 board and would like to control it by hooking it up to TrxEB and using the TI RFstudio.
I am using the TrxEB EVAL_BD, P7 connector and use the SPI lines to control my CC1120 and it works fine but cannot get the CC1190 under control using RFStudio (CC1190 always in power down mode).


In my board CC1120 GPIO0/GPIO3 are driving the CC1190 PAEN/LNAEN and they stay always LOW no matter what I select in RFStudio.
I have updated the TrxEB firmware and RFStudio to the latest versions but still CC1190 lines are not driven by CC1120 and saty LOW.

Can you please let me know how to take care of this issue? Can I change the CC1120 registers in RfStudio to change the CC1190 PAEN/LNAEN lines? If yes, which REGs and bits do I need to change?

Regards,
Reza
