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

I got some problems when using RSU in Cycone IV E device: 1: When using RSU, is it necessary to use an external trigger to trigger the FPGA to load the application image? I try to use logic to trig ...

    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 how do you write it partially, The POF checking is checking the initial part of the bitstream to contain the correct bitstream before continuing with reconfiguring the FPGA. May I know if you corrupt only the Application image?

    Hi,

    My application image is consist of 64 sectors,256KB each sector,when the first 10 sectors are writed ,i stop the update process in Host computer,,and FPGA will reconfig contiously after restating.When application image is only erased ,it can fallback successfully,and when all the contents(64sectors) are fully writen, it can update successfully.

      Besides,only the Application image is update,factory iamge will never be erased or write in update process.
