  1. ZPUino 2.0 VHDL Simulation

    Hi, I'm trying to run a VHDL simulation of the ZPUino v2 code I downloaded from Github. In my simulation environment, I've included the ZPUino v2 code and a model of the SDRAM. (However, I've not yet included a model of the SPI flash as I'm not sure how to load it and am uncertain if it's actually necessary.) In my simulation, I've also loaded the SDRAM at adress 0x1000 with a .hex (converted from .bin) version of my Arduino program. In simulation, I'm able to see the bootloader being accessed, but not long after it's completed the bootloader access, my simulation ends. What should I expect next in my simulation? I was expecting to see the program counter access the SDRAM at address 0x1000. Thanks for any help!
  2. Working on DesignLab 1.0.3 release.

    I used the DesignLab installer and only changed the default installation path. Although I haven't tried all the examples, but other sketches (which do NOT include a smallfs directory and file) seem to compile fine (note that I didn't attempt to actually load the sketches in this experiment, just compile the C code).

    Thanks for the link to the zpuino v2 VHDL. DesignLab Sketch Compile Error -- this simply uses the Arcade MegaWing example, which includes the following file: smallfs/music.ymd Found smallfs directoryC:\Users\me\Downloads\Papilio\DesignLab/hardware/tools/zpu/bin/mksmallfs C:\Users\me\AppData\Local\Temp\build5878582571163576.tmp/smallfs.dat C:\Users\me\Downloads\Papilio\DesignLab\examples\MegaWing_Arcade/smallfs SmallFS: Packed 1 files sucessfullyprocessing.app.debug.RunnerException: Error compiling.at processing.app.debug.Compiler.generateSmallFS(Compiler.java:75)at processing.app.debug.Compiler.compile(Compiler.java:106)at processing.app.Sketch.build(Sketch.java:1587)at processing.app.Sketch.build(Sketch.java:1566)at processing.app.Editor$DefaultRunHandler.run(Editor.java:2184)at java.lang.Thread.run(Unknown Source) The same problem occurs with other examples which attempt to include audio, such as:example://WING_Audio/examples/Audio_ModFile_simple/Audio_ModFile_simple.ino

    Where can I find the VHDL source code for the zpuino 2? The current DesignLab version only includes the .ngc Thx
  6. Working on DesignLab 1.0.3 release.

    I have a Papilio Pro, but the issue is with the Sketch. The sketch won't compile unless I remove the smallfs directory. The circuit loads fine.
  7. Working on DesignLab 1.0.3 release.

    In the current DesignLab version, the Arcade MegaWing example sketch won't compile. Note that if I remove the smallfs directory, though, the sketch will compile.
  8. Are there plans to include the ZPUino version 2 VHDL code in the next release of DesignLab? I can't seem to find it. Thanks.
