hroyster Posted May 23, 2018 Report Share Posted May 23, 2018 I have built a special papilio that is a clone of the papilio pro. It also has spansion flash chip that shares the address and data lines with the SD memory. I want to create a bram only zupino core that I load into the pro like board. This will free the address and data lines of the SDRAM. If I de select the SDRAM on the new board and select the spansion flash, I can then use i/o registers to transfer files from the SD card on the CL wing to the spansion flash. Then I will load the actual xilinx program that uses the flash directly with no papilio core. Is there a straight forward way to do this? My first attempt was to modify the papilio 500 project with SD cl wing and modify the ucf file to correctly connect to the pro Hardware. The xilinx loaded and verified, but the arduino load operation could not find the bram core?? error (Cannot get programmer version, aborting) I figured someone else may have tried this obvious modification of loading the smaller zupino bram only core on the pro board, but I couldn't find a reference in the forum search. Thanks in advance for any help. Howard Royster Quote Link to comment Share on other sites More sharing options...
