PS hangs up when JTAG program PL

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.

Re: PS hangs up when JTAG program PL

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.

 

Best Regards,

Srikanth

Re: PS hangs up when JTAG program PL

Hi @jerry 

In my experience, Linnux hangs if CPU_IDLE hasn't been set to off in the Petalinux BSP.

This is true if you are running Linux on your PS while programming PL with JTAG.

Hope this helps.
