|
||
|
|
connection to the target by calling the “activate physical” command. In many
|
||
|
|
interfaces, the physical can be disabled by default or overridden by user
|
||
|
|
code, which implies that an external reset sequence must be applied in order
|
||
|
|
to gain access. In other cases, the external reset must not be used, for
|
||
|
|
example when attaching to a running process. The use of external reset must be
|
||
|
|
specified in the command parameter. </p><p>Activating the physical must be followed by device ID validation, to
|
||
|
|
ensure that the session is capable of starting with the device that is
|
||
|
|
expected. For this reason, the activation command returns an ID packet
|
||
|
|
containing the device ID of the target, as read directly from the target. If
|
||
|
|
no valid device is detected, the command will return FAILED. </p><p>The GET_ID command can also be used to retrieve this value at any stage
|
||
|
|
during the session. It is read out on demand and not cached. </p><p>On completion of a session, the physical must be deactivated. The tool
|
||
|
|
disconnects from the target at this point. In order to re-connect, the
|
||
|
|
physical must be activated again. </p></div><script src="../common/main.js" type="text/javascript"><!----></script><script src="../common/splitterInit.js" type="text/javascript"><!----></script><div class="navfooter"><table summary="Navigation footer" width="100%"><tr><td align="left" width="40%"><a accesskey="p" href="ch05s03s01.html">Prev</a> </td><td align="center" width="20%"><a accesskey="u" href="ch05s03.html">Up</a></td><td align="right" width="40%"> <a accesskey="n" href="ch05s03s03.html">Next</a></td></tr><tr><td valign="top" align="left" width="40%"> </td><td align="center" width="20%"><a accesskey="h" href="index.html">Home</a></td><td valign="top" align="right" width="40%"> </td></tr></table></div></div><div id="sidebar"><div style="padding-top:3px;" id="leftnavigation"><div id="tabs"><ul><li><a tabindex="1" style="outline:0;" href="#treeDiv"><span class="contentsTab">Contents</span></a></li><li><a onclick="doSearch()" tabindex="1" style="outline:0;" href="#searchDiv"><span class="searchTab">Search</span></a></li></ul><div id="treeDiv"><img style="display:block;" id="tocLoading" alt="loading table of contents..." src="../common/images/loading.gif" /><span class="dochome"><a href="../index.html" tabindex="1">Documentation Home</a></span><span class="root"><a href="index.html" tabindex="1">Atmel EDBG-based Tools Protocols</a></span><div style="display:none" id="ulTreeDiv"><ul class="filetree" id="tree"><li><span class="file"><a tabindex="1" href="pr01.html">Preface</a></span></li><li><span class="file"><a tabindex="1" href="protocoldocs.Introduction.html">Introduction</a></span><ul><li><span class="file"><a tabindex="1" href="ch01s01.html">EDBG interface overview</a></span></li><li><span class="file"><a tabindex="1" href="ch01s02.html">Atmel EDBG-based tool implementations</a></span></li></ul></li><li><span class="file"><a tabindex="1" href="protocoldocs.cmsis_dap.html">CMSIS-DAP</a></span><ul><li><span class="file"><a tabindex="1" href="ch02s01.html">CMSIS-DAP protocol</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02.html">CMSIS-DAP vendor commands</a></span><ul><li><span class="file"><a tabindex="1" href="ch02s02s01.html">AVR-target specific vendor commands</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02s02.html">ARM-target specific vendor commands</a></span><ul><li><span class="file"><a tabindex="1" href="ch02s02s02s01.html">Erase pin</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02s02s02.html">Serial trace</a></span></li></ul></li><li><span class="file"><a tabindex="1" href="ch02s02s03.html">EDBG-specific vendor commands</a></span><ul><li><span class="file"><a tabindex="1" href="ch02s02s03s01.html">Get configuration</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02s03s02.html">Set configuration</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02s03s03.html">EDBG GET request</a></span></li><li><span class="file"><a tabindex="1" href="ch02s02s03s04.html">EDBG SET request</a></span></li></ul></li></ul></li><li><span class="file"><a tabindex="1" href="section_serial_trace.html">Serial trace commands</a></span><ul><li><span class="file"><a tabindex="1" href="ch02s03s01.html">Set transport mode</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s02.html">Set capture mode</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s03.html">Set baud rate</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s04.html">Start</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s05.html">Stop</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s06.html">Get data</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s07.html">Get status</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s08.html">Get buffer size</a></span></li><li><span class="file"><a tabindex="1" href="ch02s03s09.html">Signon</a></span></li></ul></li><li><span class="file"><a tabindex="1" href="ch02s04.html">Enveloped AVR
