Hi User,
Our PLC expert (https://e2e.ti.com/members/6176143) has looked into this, please see his reply below:

I assumed that you are using BOOSTXL-AFE031-DF1 Rev A board, see the attached User's Guide: http://www.ti.com/tool/BOOSTXL-AFE031-DF1
Although I am not fully understanding what your exact issues are, I am assuming that you do not see Transmission or Receiving signals at Power Amplifier’s output pin 42 (PA_OUT2) and Pin 43(PA_OUT1). Here are possible root causes:
Possible Issue 1:
Please check the voltage states of Pin 47 and Pin 48. They should be pulled high or in logic high. This is documented in AFE031 datasheet, see the requirements on the bottom of p. 39 in the link below. http://www.ti.com/lit/ds/symlink/afe031.pdf
Possible Issues 2:
The polarity, phase, and frequency of the clock (CLK) have been modified, all the gain values from the guide have been used and I’ve written on the registers but there’s no way to read them back so it’s not possible to know if they are modified correctly. The main GPIOs ‘mode select’ and ‘system shutdown’ are set LOW as indicated in the pdf document.
In Table 10, Command Register on p. 41 of the AFE031 datasheet, you need to enable R/W bit in Bit 15, where 1=Read and 0=Write. Please make sure that you configured the bit 15 correctly via SPI command.
If you have any other issues, please let us know. I will help you to answer questions and resolve these issue.
Best,
Raymond
