Difference Xilinx JTAG and arm PJTAG

Dear All,

 

I would like to understand the difference between the Xilinx JTAG and the ARM PJTAG used in Zynq devices.

 

Are there features available in PJTAG and not in Xilinx JTAG?

 

Is the Xilinx JTAG enough for deep debugging linux OS?

 

Is the Xilinx JTAG enough for deep ARM debugging?

 

Thank you in advance.

Re: Difference Xilinx JTAG and arm PJTAG

Using PJTAG you can access DAP. With Xilinx JTAG you can access both TAP and DAP.

 

What if you want to debug both PL and PS at the same time? Think about that.
