Sep 15 18:45:01 prpplague: did you check the mailinglist? Sep 15 18:45:14 prpplague: there were some postings a few weeks ago on that topic Sep 15 18:45:31 prpplague: btw., what does JRC stand for? Sep 15 19:06:26 drath: yea, keesj was the one doing that posting Sep 15 19:06:33 drath: Jtag Route Controller Sep 15 19:07:13 drath: http://focus.ti.com/lit/ml/sprp603/sprp603.pdf Sep 15 19:07:25 drath: that is a good explaination of the purpose of a JRC Sep 15 19:07:49 drath: almost all of the multicore SoC's are moving towards using a JRC Sep 15 19:09:31 drath: keesj and i have been looking into the changes needed to be done to openocd Sep 15 19:18:54 prpplague: will the JRC remain in enabled state? or could for example a reset cause the ARM device to disappear from the chain? Sep 15 19:34:07 drath: a hard reset will cause the arm to disappear from the chain **** ENDING LOGGING AT Mon Sep 15 19:57:33 2008 **** BEGIN LOGGING AT Mon Sep 15 20:22:16 2008 **** ENDING LOGGING AT Tue Sep 16 02:05:38 2008 **** BEGIN LOGGING AT Tue Sep 16 07:02:31 2008 Sep 16 18:05:07 drath: greetings Sep 16 18:11:00 hey prpplague Sep 17 00:25:53 http://www.sparkfun.com/commerce/product_info.php?products_id=8843 **** ENDING LOGGING AT Wed Sep 17 02:59:57 2008
