    Accessing SRAM area in DesignLab

    Any answer is appreciated!
  2. Hi, How can I access the on-board SRAM space directly in designlab? I could not find the offset address of external memory anywhere... regards.

    Loading the SPI Flash on the Papilio Pro

    Thank you magnus. I can now figure out why your bscan works and the others not! I have the same conditions on my board: Qspi flash and weak pull-Ups. regards,

    Loading the SPI Flash on the Papilio Pro

    magnus, Thank you for the point. I checked it with the bscan files under /bscan_spi_spartan6 inside your git repo (Tools_src). it worked without any problem! But It does not work with papilioprog bscan files!! Update: Altought the configuration files can be successfully programed on the spi flash thanks to new bscan files, but the zpuinoprogrammer fails to identify the flash! while with the old bscan, it does not have this issue!

    Loading the SPI Flash on the Papilio Pro

    I have recently experienced this issue with my SPI flash on my own custom board. I was able to program it just a couple days ago, but now it fails with the exactly same error: Uknown Flash Manufacturer (0x00) Error: SPI Status Register [0x00] mismatch (Wrong device or device not ready).. The interesting point is that it can be programmed by xilinx IMPACT without any problem, So I dont think that this could be a hardware issue. my software is FPGAprog from magnus with a little modification to support Winbond parts. the code is very similar to papilio-loader although. any idea please?

    microSD write issue

    You can also update the sd example sketches.

    microSD write issue

    Alvie, thanks for the replay, yes, Only write is not working. I am able to read the files easily. but I cant open any file for writing. for instance, the "readwrite" example initializes the SD successfully, but it fails at "opening test.txt" step. Although If I manually create the "test.txt" file on the microSD (by connecting it to my PC via a memory-reader), It passes the write step (no write actually!) and reads the contents of test.txt successfully! I didn't know that at-all! How can I enable it?

    Connecting VGA with jumper wires

    have you connected +3.3 and +5V signals as well as the GND between megawing and papilio pro?

    any body had tested microSD wing, please let me know if there is any special trick here. regards,

    load sketch into SPI flash

    Interesting... Thank you jack. So the bootloader automatically looks into SPI flash in the boot time and loads the software code into the RAM?

    load sketch into SPI flash

    Is it possible to load the sketch into SPI flash, along with the .bit file in designlab? (It is possible for microblaze in ISE). regards.

    strange error while burning bootloader

    After watching the Designlab introduction tutorial videos, I did not see any usage for "Burn bootloader"! Is it an option that works only for programming the AVR chip in Papilio DUO board? If so, is there any way to burn the bootloader for those sketches that are not associated with any Hardware project (e.g. blink example) in designlab IDE? (actually a way other than loading the .bit file manually to the FPGA). regards.
  14. Hi, I wonder why I am getting this strange error while I am trying to Burn bootloader to my board in designlab? Arduino: 1.0.8 (Windows 8), Board: "Papilio DUO FPGA 512KB - ZPUino" Error while burning bootloader. java.lang.NullPointerException at cc.arduino.packages.uploaders.SerialUploader.burnBootloader( at$ at java.awt.event.InvocationEvent.dispatch(Unknown Source) at java.awt.EventQueue.dispatchEventImpl(Unknown Source) at java.awt.EventQueue.access$200(Unknown Source) at java.awt.EventQueue$ Source) at java.awt.EventQueue$ Source) at Method) at$1.doIntersectionPrivilege(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at Source)

    microSD write issue

    Hi. I have ported my custom board to designlab and have run various desginlab examples on it. One problem I could not solve yet is writing files to SD card usign SD examples. The sd card could successfully being initialized and even list the files inside it. but the file open and write fails. any suggestion to solve this is appreciated!
