about starting reconfiguration~

hello,

my board has cyclone1, epcs,and ext_flash ,and so on. now, i want to start the reconfiguration, not using re_por or low_to_high conversion of reconfig pin, i see the "altremote_update Megafunction" datasheet, but it desen't supported the cyclone1, so is there anyway to start the reconfiguration? thanks.

    Why? You didn't tell in your previous thread why the suggested solution doesn't work for you. May be, there is an issue, but I didn't see it yet.

    hi,

    sorry for my poor english. i want to start the reconfiguration of fpga, and don't want to use re_por and low_to_high transformation (javascript:showjdsw('showjd_1','j_1')) of nconfig pin to start the reconfiguration, if the fpga can start the process by itself?

    Cyclone I has to dedicated remote update hardware, the only way to trigger a reconfiguration is by the nconfig pin. This is also the most simple way. I don't yet understand, why you don't want to use this option.

    hi,

    i don't want add extra electrocircuit (javascript:void(0)), so i want to know if the fpga can reset itself via doing some operation.
