Hi, I'm working on a project to get a C64 emulator running on the Papilio DUO. I have a working setup using uno2iec program to emulate the disk drive, but this still requires a laptop connected to the board. I found a project named sd2iec, that uses the SD card to load disk images of, but the compiled program is too big to fit on the ATMega32U4 together with a bootloader. So I need a way to program the AVR directly. I Googled for documentation on how to use the bootloader program routine to upload my software as well, but couldn't find any. Is there a way to program the AVR on the Papilio DUO without bootloader via USB using for example avrdude? Kind regards, Paul
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(SerialUploader.java:339) at processing.app.Editor$62.run(Editor.java:2907) 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$3.run(Unknown Source) at java.awt.EventQueue$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$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 java.awt.EventDispatchThread.run(Unknown Source)
Hello, I was wondering if anyone could point me in the right direction on a problem I am having. I am trying to understand the ZPUino system and I want to make a customized core for my project so I am trying to just figure out how the whole project source fits together. I can compile a with whatever core changes I intend on making bit successfully. There is a bootloader section in the repository which has debug and verbose options. I am attempting to just enable verbose options as an exercise in understanding how all the pieces fit together. I can build the bootloader code successfully I have searched but I cant seem to find any information on how to integrate a custom bootloader with a custom core. In a previous post i read that the ZPUino doesnt use a bmm file so how do you integrate the bit with the hex of the bootloader. Could anyone point me in the right direction. Thanks
