Summary: Support for AVRISP mkII USB programmer Project: AVR Downloader/UploaDEr Submitted by: None Submitted on: Wed 01/11/06 at 17:27 Category: None Priority: 5 - Normal Status: None Privacy: Public Assigned to: None Originator Email: [EMAIL PROTECTED] Open/Closed: Open _______________________________________________________ Details: Recently, Atmel has discontinued their serial-based AVRISP programmer, and now sell the AVRISP mkII, which is basically identical, except the serial interface has been replaced with a USB interface. This patch adds support for the AVRISP mkII. The command format is identical to the existing STK500v2 support with one exception: the range of supported SCK values is different. Thus, the patch adds support for this new range of SCK values. In order to use a AVRISP mkII programmer, simply specify STK500v2 as the programmer, and use the "-P usb" option to indicate that it is connected via USB. A few modifications were necessary to usb_libusb.c since the AVRISP mkII does not encapsulate its frames in the same format as the jtagmkII. Instead, it does not encapsulate frames at all, and just relies on the USB packet boundaries to indicate the frame boundaries. A short packet must always terminate a command or response. This required adding a new type of recv command to usb_libusb.c. _______________________________________________________ Carbon-Copy List: CC Address | Comment ------------------------------------+----------------------------- dcm --AT-- mit --DOT-- edu | Originator Email _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Wed 01/11/06 at 17:27 Name: avrispmkII.patch Size: 10.13KB By: None Patch file <http://savannah.nongnu.org/patch/download.php?item_id=4789&item_file_id=5752> _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?func=detailitem&item_id=4789> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@nongnu.org http://lists.nongnu.org/mailman/listinfo/avrdude-dev
