Hello,
We are interested in use of Polarfire FPGA’s. I made research from your website and found some documents about the secure boot mode of Polarfire.
What I would like to learn is, is it possible to program PL (fpga) from PS in Polarfire? I think, as a flash-based FPGA, polarfire FPGA reads its configuration from its own flash. We would like to change and program the configuration of FPGA from PS, is it possible? If it is, how can we manage it?
