Dear all

I am using AD9361 for LTE FDD Pico cell device, I meet the problem with self generator internal AD9361BIST function.  

- On evaluation RF from benetel , after configuration, i change the ensm from alert to fdd by write value 0x23 to 0x14. Then enable the BIST function, it generate a tone.

- I try to do like this with my board, when change the ensm from alert to FDD by write value 0x23 to 0x14, then I read back all registers value. All is 00, all configuration is gone.

 

Can some ones let me know why?

Please see my attached for more dentail.

 

Thanks all, hope your response.
