How to reset PL by PS when booting in UltraScale+

Jump to solution

I am trying ot reset PL part by PS when booting.

If I am thinking right, when I see Ultrascale EV board user guide(zcu102, zcu104, zcu106), there is PL reset called 'CPU reset'.

I want to replace 'CPU reset' in PS like 'pl_reset0'. Is it possible to make 'pl_reset0' to CPU reset?

Is there no error when I make CPU reset by PS in UltraScale+?

 

Thank you.

Hi @chlwogns414,

If you want to reset PL from PS, you can use any GPIO through the EMIO.
