Hi


Unfortunately, there is not much documentation on this.

I could not find out why a full configuration option is enable where it is not able to be run.

But in general when configuring the FPGA from linux, we should not do a full configuration as the full configuration will cause the hps to be configured and the linux will crash.

    Hi,

    thank you very much for your support.

    We are only writing the full RPD file (firmware) without making any changes to the HPS.

    As far as we understand, this file only contains the FPGA firmware and should not affect the HPS, correct?

    What should we do next, and where can we get further support?

    Thanks again!

    Best regards
