  1. Hi Jack Thank you very much! It's working now as it should... I have 2MB SRAM on the DUO, and I can use 100% of it :-)
  2. Hi Jack It's the samen with the bit file from Papilio DesignLab 1.0.8 -> File -> Examples -> Papilio_DUO_QuickStart on my Papilio DUO 2MB.

    I have the same problem. On my pc I have pluged in other ftdi devices (e.g. usb-rs232-converter). If I unplug the other ftdi devices I can download to the papilio :-)

  5. Does it need any more information or explanation? I have 2MB SRAM on the DUO, but I can only use 25% of it (~500KB).
  6. Hi I'm working with Papilio DUO, Papilio DesignLab 1.0.8 and ZPUino SOft Processor Vanilla v2.0. I'm just testing how much RAM I can use in my sketch. For this reason I increase the size of an array (unsigned char). The sketch below with an array size of 501*1024 bytes is not running. The same sketch with an array size of 500*1024 is working fine. static unsigned char bufferRAM[501*1024]; void setup(){ pinMode(13, OUTPUT); Serial.begin(115200); } void loop(){ digitalWrite(13, HIGH); delay(100); digitalWrite(13, LOW); delay(100); Serial.print(bufferRAM[0]); Serial.println("Hello..."); } Compiler output: Binary sketch size: 515.216 bytes (of a 2.048.000 byte maximum) - 1.728 bytes ROM, 513.640 bytes memory, 25% used Der Sketch verwendet 1.576 Bytes (0%) des Programmspeicherplatzes. Das Maximum sind 2.048.000 Bytes. Globale Variablen verwenden 152 Bytes des dynamischen Speichers. What can be the reason? The Papilio DUO Hardware Guide website says: The ZPUino Soft Processor integrates the SRAM which gives your ZPUino sketches 512KB or 2MByte of code space! Thank you for your help!
