Transition from FDD mode to TDD mode in Ad9361

Hello,

 

I am using the Linux driver to configure the Ad9361 chip. The Ad9361 chip (ARradio) is connected with Altera SocKit .

 

I would like to know that how can i make a transition from FDD mode to TDD mode using shell command. The default state of the ensm mode is fdd and register value of 0x013 is 0x1.

 

I tried to change the register value to 0x0, which states for TDD mode but still I am in fdd mode and after 2-3 minutes the register value again changes back to its default value 0x1.

 

I have checked using ADI IIO oscilloscope. Also,  I have seen the instructions that has been given on this webiste (https://wiki.analog.com/resources/tools-software/linux-drivers/iio-transceiver/ad9361) but there is no information for the transition from FDD mode to TDD mode using shell command.

 

So, Can you please tell me the shell command and also tell me that how can i change the register value permanently?

 

Regards,

Mukesh
