Does python command change the bitstream

Support

I use rfsoc 4*2, version 3.
There are some packages like rfsoc_sam, pynq.overlays.base, nco… that we can initialize at the beginning, and it will download the “base.bit” file to the PL.
The question is after then, we can input some python commands interactively, will the commands change the original .bit file that is downloaded at the beginning.
What I thought is, the interactive python commands only use the drivers to control the IO, is it right? Or these commands also change the .bit file, besides the corresponding PL.

Thanks.

Hi @zwan,

will the commands change the original .bit file that is downloaded at the beginning.

No, the bitstream is untouched. But the IP can be configured via the registers that are memory mapped.
