When I program ZYNQ 7z014s PL (lasts approximately 3 seconds), PS sometimes work properly, but hangs up more often because there is no responds on UART. Is it because there is any conflict at polling code to JTAG ?
PS is communicating with PL through AXI all the time at its main polling, every polling cost about 1ms.

Hi @jerry ,
Looks like the PS is requesting data from PL ending up in hang state. make sure that there are no dependencies from PL. If the PS is trying to access any address in PL before it gets programmed, then the PS would enter into hang state.
