Can't use linux after configuring the FPGA !!

Hi ,

I have an arria 10 SoC devkit, i have the default GSRD on HPS that contains the default partial reconfiguration rbfs (core.rbf , periph.rbf) , when i try to configure the FPGA using Quartus programmer tool with another design the linux stops and i can't access it neither by serial or by SSH ,

need help any ideas ?

Thank you

    If the software is trying to access a module in the FPGA while it is reconfigured, the CPU can hang. Check also that the relevant HPS2FPGA bridges are enabled. Can you do a reset of the CPU after you have configured the FPGA?

    thank you for the response, no i can't the only thing i can do is restarting the board, and the software is not trying to access any module in the FPGA when i reconfigure it,

    i will check if the HPS2FPGA bridges are enabled but i don't think that's problem,
