I have some issue with fmcomms4 and zedboard. the process is:

First PL config ad9364 in tx at 2.4G, when I received some IQ data, use PL to process it, then I need to switch to tx mode to send some other data out, the whole process should in useconds level. Then I will repeat this at other frequency. But the problem is use PL to config ad9364 is complicated(from my understand, no exist lib), can I use no-os api? what's the latency level? how can my FPGA code communicate(synchronise) with my baremetal code? and what's the best practice for my usage?
