Clear PCAP_PR (bit 27) in the PS device configuration control register (DEVCFG CTRL, address 0xF8007000)

Hello there,

  • Linux image: PYNQ V2.5
  • Board: TUL PYNQ-Z2

I would like to use SEM IP for PYNQ, controlling the Error injections with the PS part of the Zynq using Jupiter Notebook.

But I should clear the PCAP_PR bit in the PS device configuration, in order to transfer the configuration memory injection to SEM IP using ICAP. (Page 57, PG036)

How could I clear/ set this bit from linux? What files should I modify in order to modify this bit?

Thanks and Best Regards.

If you know the register address, you can probably use the Register() class from pynq package. We use the same class to configure clock registers as well.

It seems to work. Now I will try to integrate with my application.
