Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: svenq (svenq) Assigned to: Nobody/Anonymous (nobody) Summary: Avarice dies with timeout upon memory read Initial Comment: Avarice dies with a receive timeout when reading memory from an ATMega32u4 via JTAG, after apparently correct initialization. MCU: ATMEGA32U4 Tools: AVR JTAG ICE mkII, FW 7.28 or FW 6.x Avarice 2.10, 2.12 or 2.13 on Gentoo Linux or Debian Linux avr-gdb 7.2 or 7.6 Same setup works with AVR Studio 6 ---------------------------------------------------------------------- >Comment By: Joerg Wunsch (joerg_wunsch) Date: 2012-11-16 09:18 Message: The main difference between both appears to be the use of the undocumented command 0x36, rather than the old CMND_SET_DEVICE_DESCRIPTOR. So far, I assumed command 0x36 is only used for Xmega device, but perhaps it is to be used in general now. In addition to the already known usage (with a 0x0002 as the initial value of the configuration record), it seems the IO register bitmaps are also configured through command 0x36, but with initial values 0x0080, 0x0081, 0x0088, 0x0089. This configuration method looks very similar to what the JTAGICE3 uses (see the respective feature request and attached USB trace). ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=425407&aid=3587834&group_id=39505 ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
