URL: <http://savannah.nongnu.org/patch/?6825> Summary: xmega problems with JTAGICEmkII Project: AVR Downloader/UploaDEr Submitted by: zladay Submitted on: Fri 08 May 2009 10:13:15 AM GMT Category: None Priority: 5 - Normal Status: None Privacy: Public Assigned to: None Originator Email: Open/Closed: Open Discussion Lock: Any _______________________________________________________ Details: I am attaching a patch that fixes some xmega problems on JTAGICEmkII. Added support/resolved issues: - handling (r, w, v) of the following memory types * EEPROM * flash (including sections: application, application table and boot) * fuse bytes (0, 1, 2, 4, 5) * JTAG signature * lockbits * production signature * user signature Supported xmega MCUs: - 128a1d, 128a1, 192a1, 256a1 - 64a3, 128a3, 192a3, 256a3, 256a3b - 16a4, 32a4, 64a4, 128a4 It was tested with an x128a1 only. Support for the rest is based on the documentation only and is not tested. Fixed bugs: Segmentation fault caused by buffer overflow in jtagmkII_paged_load() in jtagmkII.c. Known issues: - writing of user signature failure at verification (contents differ from data written) - writing of EEPROM failure at verification (contents differ from data written) - the same behavior is experienced with the recent [4.16.628] version of AVR Studio - no working reference implementation is known Still to do (among others) - PDI physical interface support - recent version works with JTAG only - erase operations (chip, flash, application, boot, EEPROM, user signature) _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Fri 08 May 2009 10:13:15 AM GMT Name: avrdude-jtagicemkii-xmega.patch Size: 37kB By: zladay <http://savannah.nongnu.org/patch/download.php?file_id=18118> _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?6825> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@... http://lists.nongnu.org/mailman/listinfo/avrdude-dev |

Follow-up Comment #1, patch #6825 (project avrdude): I finally got the time to test the patch. Sorry for taking forever. Alas, with the patch, JTAG programming completely fails for me. This is just a first test, so I didn't try to isolate the hunk(s) of the patch that makes it fail. The symptom is that it starts out fine, but reads only garbage: avrdude: Yikes! Invalid device signature. avrdude: Expected signature for ATXMEGA128A1REVD is 1E 97 41 avrdude> d fuse4 >>> d fuse4 0000 00 |. | avrdude> d fuse2 >>> d fuse2 0000 00 |. | avrdude> d flash >>> d flash 0000 00 00 00 00 01 00 00 00 00 00 00 40 00 00 10 00 |...........@....| 0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| avrdude> d ee >>> d ee 0000 00 00 00 00 01 00 00 00 00 00 00 40 00 00 10 00 |...........@....| 0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| In contrast, without the patch, at least the minimal functionality is OK: avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.01s avrdude: Device signature = 0x1e9741 avrdude> d flash >>> d flash 0000 0e 94 40 00 0e 94 2b 00 0e 94 4d 00 05 e0 00 93 |..@...+...M.....| 0010 05 02 00 93 45 02 00 91 16 02 10 91 56 02 01 23 |....E.......V..#| 0020 01 30 c9 f7 00 91 08 02 00 93 64 06 0e 94 4d 00 |.0........d...M.| 0030 00 91 09 02 00 93 64 06 0e 94 4d 00 00 91 48 02 |.. ...d...M...H.| avrdude> d ee >>> d ee 0000 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 0010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 0020 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 0030 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| avrdude> d fuse4 >>> d fuse4 0000 1e |. | avrdude> d fuse5 >>> d fuse5 0000 f7 |. | avrdude> d lock >>> d lock 0000 ff |. | _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?6825> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@... http://lists.nongnu.org/mailman/listinfo/avrdude-dev |

Follow-up Comment #2, patch #6825 (project avrdude): I just noticed I mistyped the command. So, without the patch, EEPROM access doesn't work either, only the signature could be read. (The above data were collected using -c stk600.) _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?6825> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@... http://lists.nongnu.org/mailman/listinfo/avrdude-dev |

Follow-up Comment #3, patch #6825 (project avrdude): From the symptoms, it seems to me that you have not refreshed avrdude.conf. That should remedy the situation. JTAG signature handling should at least surely work. There are however still problems with EEPROM read e.g.. I am submitting a newer patch that fixes most of these. This new patch is against the SVN head (version 819). This should be easier to integrate. With this patch, memory handling should work (flash, EEPROM). I am using this patched version of avrdude on Mac OS for programming an x128a1 routinely. It is fairly stable. This has been reported by a user on Linux, too. There has been one issue reported. If flash programming is finished, the target board does not start to run the new code. A manual reset is required. Features not dealt with: - chip erase functions - PDI physical interface support _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?6825> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@... http://lists.nongnu.org/mailman/listinfo/avrdude-dev |

Update of patch #6825 (project avrdude): Status: None => Done Assigned to: None => joerg_wunsch Open/Closed: Open => Closed _______________________________________________________ Follow-up Comment #4: Oops, sure, you are right: I forgot to add -C avrdude.conf to use the local copy of it, rather than the installed version. Thanks a lot, I committed it to SVN now. Fuse changes appear to require leaving and re-entering programming mode on the Xmega in order to take effect. This is still not handled yet. As it can also be noticed on the STK600/PDI, it should probably be handled in a more generic way than per-programmer. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/patch/?6825> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/ _______________________________________________ avrdude-dev mailing list avrdude-dev@... http://lists.nongnu.org/mailman/listinfo/avrdude-dev |
