GTL setup for Emulator debug 문서 원본 보기

<h2>GTL Configuration</h2>
<p>Emulator Debug 환경에서는 기본적으로 개발환경에 따라 다음 3가지 환경을 구성할 수 있습니다.</p>
<p><span style="font-size: large;">&nbsp; 1) SMP 또는 Single core debugging 환경 : 아래 Configuration 1 참조</span></p>
<p>&nbsp; &nbsp; &nbsp;- 가장 간단하며 Emulation Host와 TRACE32 PowerView가 같은 Host상에 위치합니다.</p>
<p><span style="font-size: large;">&nbsp; 2) AMP &nbsp;debugging 환경 : 아래 Configuration 2 참조</span></p>
<p>&nbsp; &nbsp; &nbsp;- Emulation Host와 TRACE32 PowerView가 같은 Host상에 있으나 AMP 지원을 위해 여러개의 PowerView를 실행합니다.</p>
<p><span style="font-size: large;">&nbsp; 3) AMP debug 환경 및 Network Access debugging : 아래 Configuration 3 참조</span></p>
<p>&nbsp; &nbsp; &nbsp;- Emulation Host와 TRACE32 PowerView가 각각 별도의 Host에서 동작하므로 Network을 통해 연결됩니다. 따라서</p>
<p>&nbsp; &nbsp; &nbsp; &nbsp;TRACE32 PowerView를 개발자 PC에서 실행하여 연결할 수 있으므로 매우 간편하게 사용할 수 있습니다.</p>

<h2>GTL debug environment 설정</h2>
<p>상기 3가지 동작 Mode는 TRACE32 실행 시 기본적으로 참조하는 config.t32 파일의 <strong>PBI 설정</strong>에 따라 결정되며</p>
<p>각 동작 Mode의 설정은 다음과 같습니다.</p>
<ul>
<li>
<h3>Setup for Configuration 1</h3>
</li>
</ul>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PBI=MCILIB ; configure system to use hostmci.so</span></p>
<p>&nbsp;</p>
<ul>
<li>
<h3>Setup for Configuration 2</h3>
</li>
</ul>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PBI=MCISERVER&nbsp; </span><span>; set up the usage of hostmci.so and </span><span>open</span></p>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;PORT=30000&nbsp; </span><span>; server at 30000 for the first instance</span><span>.</span></p>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;INSTANCE=AUTO&nbsp; </span><span>; consecutive number of </span><span>instance for AMP setup</span></p>
<p>&nbsp;</p>
<ul>
<li>
<h3>Setup for Configuration 3</h3>
</li>
</ul>
<div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 본 설정은 두가지 고려사항이 필요합니다. 상기 그림에서와 같이 Emulation Host side에서는 TRACE32 PowerView의</div>
<div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 디버그 명령을 받아 Emulator에 전달하는 MCI server라고 하는 Module을 먼저 실행해 주어야 하며 다음으로</div>
<div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PowerView를 다음 설정으로 설정한 후 실행하게 됩니다.&nbsp;</div>
<div><strong>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; *&nbsp;Invoke MCI-server first in Emulation Host side</strong></div>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&gt;&gt; </span><span>./</span><span>t32mciserver port=30000 ; start t32mciserver at port 30000</span></p>
<div><strong>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; * CONFIG.T32 for Trace32 debugger side</strong></div>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PBI=MCISERVER&nbsp; </span><span>; set up connection to </span><span>t32mciserver</span></p>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; NODE=192.168.0.1&nbsp; </span><span>; connect to IP 192.168.0.1 </span></p>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PORT=30000&nbsp; </span><span>; at port 30000</span></p>
<p><span>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; INSTANCE=AUTO&nbsp; </span><span>; consecutive number of </span><span>Trace32 instance for AMP setup</span></p>
<p><span><br /></span></p>
<h2>TRACE32 PowerView 실행 후 Emulator 연결</h2>
<p>TRACE32 사용 시 Physical JTAG 디버그 환경과 다른 점은 오직 Emulator 연결을 위한 설정만 다릅니다. 즉 기존에 사용하던</p>
<p>.cmm Script들을 그대로 사용할 수 있으며 GTL관련 내용만 추가하면 되겠습니다.</p>

<p>TRACE32 PowerView는 개발자로 하여금 타깃의 현재 상태를 명확히 볼수 있도록 내부적으로 초당 수십회의 타깃 상태정보를 읽어</p>
