Yes I can reproduce the issue with Luminary EK-LM3S1968 board, with the latest firmware it failed just like your previous post. Then if I downgrade the firmware to 4.08i and OpenOCD will work. For those who want to downgrade the firmware, here is the doc. http://www.segger.com/cms/admin/uploads/productDocs/UM08001_JLinkARM.pdf (Section 9.5) This is a known problem. http://www.segger2.com/index.php?page=Thread&threadID=869 http://comments.gmane.org/gmane.comp.debugging.openocd.devel/16831 http://www.segger2.com/index.php?page=Thread&threadID=707 (4.10i works, 4.22 failed) -- Xiaofan _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
