I was trying to understand loopback in picozed sdr kit ad9361 no os application using example files.
1. What is the difference in BIST Loopback and HDL Loopback?
2. Loopback functions are in ad9361.c,ad9361.h and ad9361_conv.c - How to enable loopback and how to see the result?
3. Are we using BIST Signal generator in above files for loopback?
4. There are 2 types of loopback in ad9361 - RF Section Active/Inactive. How to test/check each one of these?
5. In loopback is it--- data injected at Rx AND WATCHED AT tX PORT OR tX TO Rx? Where to check loopback data? do i require chipscope or any tool?
