  1. You can also update the sd example sketches. Sent from my LG-K430 using Tapatalk
  2. Thank you so much. It solved the issue! Sent from my LG-K430 using Tapatalk
  3. 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?
  4. have you connected +3.3 and +5V signals as well as the GND between megawing and papilio pro?
  5. any body had tested microSD wing, please let me know if there is any special trick here. regards,
  6. Interesting... Thank you jack. So the bootloader automatically looks into SPI flash in the boot time and loads the software code into the RAM?
  7. 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.
  8. 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.
  9. 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)
  10. 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!
  11. Thank you. It is solved now.
  12. I'm trying to build ZPUino on my windows machine with Cygwin, ISE and perl installed on. I downloaded the last version of ZPUino-HDL from alvie's git repo, then I started by 'Make'ing the content of 'papilio-pro/../designlab' folder, but at the first stage, I encountered this error: ERROR:Xst:2927 - "\ZPUino-HDL-master\zpu\hdl\zpuino\boards\papilio-pro\S6LX9\variants\designlab\ZPUino_Papilio_Pro_V2_blackbox.prj" line 6: Source file ../../../../../prescaler.vhd does not exist I can find the prescaler.vhd under '/lib' folder. So, Maybe I am not using the most recent version of repository. Please help me what's wrong? regards. Edit: Even after fixing the above issue by setting files path manually, I got other errors: ERROR:HDLCompiler:432 - "D:\ZPUino-HDL-master_alvie\ZPUino-HDL-master\zpu\hdl\zpuino\boards\posedge_one\S6LX9\variants\designlab\posedge_one_top.vhd" Line 720: Formal <m_wb_cti_i> has no actual or default value. INFO:HDLCompiler:1408 - "D:\ZPUino-HDL-master_alvie\ZPUino-HDL-master\zpu\hdl\zpuino\zpuinopkg.vhd" Line 83. m_wb_cti_i is declared here I wonder if there is anything wrong in my setup or it is a source code issue?
  13. Jack, Do you use automatic assembly for your boards or house-assembly? And just as a suggestion: Wouldn't it be better if you length-match all IO pins to each other? It may be possible that someone wants to design a high-speed peripheral (e.g. HDMI wing) for papilio nano in the future and it comes handy then.
  14. Jack, May I ask why did you prefer mini-usb rather than micro-usb? As the micro-usb is more rigid in terms of plug-unplug cycles compared with mini-usb (10,000 vs 5000). [link]
  15. great work! Can it be used along with xilinx tools (like papilio-due)? did you check the price with the manufactures? I am very eager to hear more about manufacturing steps involved in such a project.
