How to write VHDL code into SD Card SO THAT I DON'T NEED TO COMPILE EVEERY TIME I SWITCH ON THE de0 BOARD?
What exactly do you mean?The easiest way would be to buy an SD card reader and then copy the files from the PC to the SD card. I dont see how this relates to VHDL though, as it applies to any files?
I believe, this is the third time, the user is asking the same question. I guess he simply wants to know how to store an FPGA configuration non-volatile.One possible method is described in the DE0 Users manual "Configuring the EPCS4 in AS Mode".
