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...
hroyster Posted May 23, 2018 Author Report Share Posted May 23, 2018 As a follow up, I noticed that the ucf callout for the usb_tx and usb_rx seemed to be reversed from the pro ucf so I switched them (not sure about why this worked). When I did, the arduino programmer did not error on the missing core but generated the following error which looks like it found the core but did not see what it wanted to see. error - Board: Unknown board @ 96000000 Hz (0xb4010f00) Cannot program flash on non-sector boundaries! I thought the Bram flash ( i assume this is the program space in the bram flash) would be placed in the same place in the core but maybe not - there must be some ID issue. I have attached the project if any one has a chance to take a quick look. Thanks again for any help. Howard Flash_SD_2.7z Quote Link to comment Share on other sites More sharing options...
LenBiar Posted August 30, 2019 Report Share Posted August 30, 2019 Thanks Jorg.....on closer inspection, I think she has been refinished, so scratchplate may well not be original......but very well done if not original......knobs defo not original, and I wonder what they should be like?
