When using RSU, is it necessary to use an external trigger to trig FPGA to load application image?

    Hi,

    The pof_error only performed sanity check and not full check. So if the initial bitstream is correct then it will try to configure the FPGA with application image. The pof_error will only detect if there is some error on the initial bitstream.

Hi,

May I know if it is stuck in the loop that when it load the factory image then it will try to reconfigure to application image? Or is there a way to stop the configuration when it is reverting to factory image after failure?

    Hi,

    It can load application image successfully and will not stuck in the loop when both two images are complete,but it will stuck in the loop when application image is corruptted. As far as i am concerned,pof_error is supposed to go high after failure,and it should remain high,so even if it revert to factory image after failure,reconfiguration should not be trigged.
