  1. 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!
  2. 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 :-)
  3. 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 :-)

  6. Does it need any more information or explanation? I have 2MB SRAM on the DUO, but I can only use 25% of it (~500KB).
