&lt;p&gt;你好，&lt;/p&gt;
&lt;p&gt;在 MSPM0G3507 上使用 MSPM0 SDK 2.11.00.07 时，通过 SysConfig 添加/配置 DMA Channel 会触发 GUI 崩溃。同一套 DMA 操作在 SDK 2.10.00.04 上正常。&lt;/p&gt;
&lt;p&gt;【环境】&lt;br&gt;- 器件：MSPM0G3507&lt;br&gt;- 封装：LQFP-48 (PT)&lt;br&gt;- MSPM0 SDK：2.11.00.07&lt;br&gt;- SysConfig（.syscfg 头信息）：tool 1.26.2+4477&lt;br&gt;- .syscfg 中的 product：mspm0_sdk@2.11.00.07&lt;br&gt;- 使用方式：CCS 内置 SysConfig（webview）&lt;/p&gt;
&lt;p&gt;【问题现象】&lt;br&gt;打开 SysConfig，尝试添加新的 DMA Channel（或选中已有不完整的 DMA Channel）时，界面报错：&lt;/p&gt;
&lt;p&gt;&amp;nbsp; Unable to render selection&lt;/p&gt;
&lt;p&gt;&amp;nbsp; TypeError: Cannot read properties of undefined (reading &amp;#39;attributes&amp;#39;)&lt;/p&gt;
&lt;p&gt;调用栈：&lt;br&gt;&amp;nbsp; at Object.getAttribute (...\mspm0_sdk_2_11_00_07\source\ti\driverlib\.meta\Common.js:3673:34)&lt;br&gt;&amp;nbsp; at hasLongLongOption (...\mspm0_sdk_2_11_00_07\source\ti\driverlib\.meta\DMAChannel.syscfg.js:412:19)&lt;br&gt;&amp;nbsp; at getLengthOptions (...\mspm0_sdk_2_11_00_07\source\ti\driverlib\.meta\DMAChannel.syscfg.js:375:8)&lt;br&gt;&amp;nbsp; at ...\ui.js (getOptions / getUIOptionsImpl)&lt;/p&gt;
&lt;p&gt;【本地分析】&lt;br&gt;SDK 2.11 的 DMAChannel.syscfg.js 中有：&lt;/p&gt;
&lt;p&gt;&amp;nbsp; function hasLongLongOption() {&lt;br&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; return Common.getAttribute(system.deviceData.peripherals["DMA"], &amp;quot;SYS_DMA_MMR_LLONG&amp;quot;) == &amp;quot;1&amp;quot;;&lt;br&gt;&amp;nbsp; }&lt;/p&gt;
&lt;p&gt;在 MSPM0G3507 的 deviceData.peripherals 中，看到的是 DMA_CHx（如 DMA_CH0、DMA_CH1&amp;hellip;），并没有名为 &amp;quot;DMA&amp;quot; 的 peripheral。&lt;br&gt;因此 peripherals["DMA"] 为 undefined，Common.getAttribute() 访问 .attributes 时崩溃。&lt;/p&gt;
&lt;p&gt;对比 SDK 2.10.00.04：getLengthOptions() 使用器件族判断&lt;br&gt;（isDeviceFamily_PARENT_MSPM0GX51X / G352X 等），对 G3507 会安全跳过 LonLong，不会崩溃。&lt;/p&gt;
&lt;p&gt;【补充说明】&lt;br&gt;- MSPM0G3507 头文件（mspm0g350x.h）未定义 DMA_SYS_MMR_LLONG（不支持 128-bit DMA），LonLong 本应直接不可用，而不是导致 GUI 崩溃。&lt;br&gt;- 使用 SDK 2.10.00.04 且 DMA Channel 配置完整的其他工程工作正常。&lt;br&gt;- 升级/使用 SDK 2.11.00.07 后，在 SysConfig 中一添加 DMA Channel 就会触发该错误。&lt;br&gt;- 这更像是 2.10 &amp;rarr; 2.11 之间 SysConfig DMA meta 的回归，而不是应用层配置问题。&lt;/p&gt;
&lt;p&gt;【希望确认】&lt;br&gt;1）是否确认这是 SDK 2.11.00.07 SysConfig DMA 模块的已知问题？&lt;br&gt;2）是否有官方规避方法，或计划修复（例如对 peripherals["DMA"] 判空，或恢复 2.10 的器件族判断方式）？&lt;br&gt;3）在正式修复前，对 G3507 + SDK 2.11 用户，是否推荐：手写完整 .syscfg，或本地修改 hasLongLongOption()？&lt;/p&gt;
&lt;p&gt;谢谢。&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/127/2210.image.png" alt="image.png" data-temp-id="image.png-113866"&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>LM5116-5116WG-25116DESIGN-CALC: LM5116官方电源设计器设计的模板，在Tina仿真的时候出错，仿真芯片各个引脚输出电压如图。我输入+24V需要输出-24V</title><link>https://e2echina.ti.com/thread/1087595?ContentTypeID=0</link><pubDate>Thu, 06 Aug 2026 05:43:14 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:63adecfd-42af-4adb-a2a3-85ec642a1950</guid><dc:creator>junyu junyu</dc:creator><slash:comments>1</slash:comments><comments>https://e2echina.ti.com/thread/1087595?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1087595/lm5116-5116wg-25116design-calc-lm5116-tina-24v--24v/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/tool/cn/LM5116-5116WG-25116DESIGN-CALC" class="internal-link folder tool" title="Link to Tool Folder" target="_blank"&gt;LM5116-5116WG-25116DESIGN-CALC&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/127/1738.image.png" alt="image.png" data-temp-id="image.png-194679"&gt;21&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/127/4442.image.png" alt="image.png" data-temp-id="image.png-144074"&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>UCC28950: 计算EXCEL工作表取消保护</title><link>https://e2echina.ti.com/thread/1087590?ContentTypeID=0</link><pubDate>Thu, 06 Aug 2026 02:11:44 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:9643c7da-f09e-4e58-a125-06715799a83e</guid><dc:creator>n y</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1087590?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1087590/ucc28950-excel/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/UCC28950" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;UCC28950&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;ucc28950的 &lt;span style="font-size:12pt;"&gt;SLUC222.excel 文件中关于电压补偿的计算公式与手册中不符，如何取消工作表保护密码进行更改&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>TMUXHS5212-EVM-DOC-CERT: tmux646</title><link>https://e2echina.ti.com/thread/1087264?ContentTypeID=0</link><pubDate>Thu, 30 Jul 2026 10:37:17 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:b539cde7-7a80-4590-a3e2-81bbaf8fbdc6</guid><dc:creator>Deemo Gao</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1087264?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1087264/tmuxhs5212-evm-doc-cert-tmux646/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; TMUXHS5212-EVM-DOC-CERT&lt;br /&gt;&lt;b&gt;Other Parts Discussed in Thread:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/TMUX646" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TMUX646&lt;/a&gt;&lt;/p&gt;&lt;p&gt;抱歉，我没有在型号里找到TMUX646，所以随便选了一个型号。&lt;/p&gt;

&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;This is question from a book. I edit in Pspice and wish a solution like solution same as from book. where did I do wrong?&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;if I have other quetion, is there a good place that I could ask because I think this forum is little complex. I wish a wechat group that can solve problem quickly or other means.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>TPA3255-Q1: 关于TPA3255的GVDD串连电阻和并联电容的使用问题</title><link>https://e2echina.ti.com/thread/1085571?ContentTypeID=0</link><pubDate>Tue, 21 Jul 2026 12:14:21 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:1c257c87-6d27-41e6-9f6f-b74e5956599a</guid><dc:creator>Hongye WEI</dc:creator><slash:comments>8</slash:comments><comments>https://e2echina.ti.com/thread/1085571?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1085571/tpa3255-q1-tpa3255-gvdd/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/TPA3255-Q1" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TPA3255-Q1&lt;/a&gt;&lt;br /&gt;&lt;b&gt;Other Parts Discussed in Thread:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/product/cn/TPA3255" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TPA3255&lt;/a&gt;,&lt;/p&gt;&lt;p&gt;你好，我是用三个TPA3255做一件6通道的音频功放，原理图是按规格书做的，其中PVDD是从GVDD（主路电压是36V15A）通过DC-DC降压到12V/1A，提供给GVDD的，电压电流非常稳定。但是我发现一个问题，当三个TPA3255的GVDDA/BC/D同时串有3.3欧姆，并联0.1UF对地时，功率输出上来一点点，就会进入保护了。把三个TPA3255的GVDDA/BC/D引脚上的0.1UF全部去掉之后，输出失真到30%THD，都不会保护（这样输出才是正常的）。如果停掉其中两个TPA3255不用，只保留一个的话，GVDD有0.1U电容，那么输出也是正常的。反正就是有两个或者3个TPA3255同时运行就不行。分开独立时钟运行也不行，共用时钟也不行。&lt;br&gt;&lt;br&gt;那么我的疑问是，当同时使用多个TPA3255一起工作时，去掉这GVDD上的0.1UF电阻，只保留这个3.3欧姆电阻，是否可靠运行？或者这个RC改如何取值呢？&lt;br&gt;&lt;br&gt;谢谢&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>UCC28750-SIMPLIS: 在之前卸载过一次后pspice安装失败，无法弹出正常的安装页面</title><link>https://e2echina.ti.com/thread/1085374?ContentTypeID=0</link><pubDate>Mon, 20 Jul 2026 06:36:46 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:ce4009af-d693-4cdc-9f9f-d933bba2c745</guid><dc:creator>lizihao li</dc:creator><slash:comments>1</slash:comments><comments>https://e2echina.ti.com/thread/1085374?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1085374/ucc28750-simplis-pspice/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; UCC28750-SIMPLIS&lt;br /&gt;&lt;/p&gt;&lt;p&gt;在之前卸载过一次后pspice安装失败，在以管理员身份运行时会闪退，无法弹出正常的安装页面&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>CCSTUDIO-THEIA: CCS Theia SysConfig Switch not working for MSPM0G3507</title><link>https://e2echina.ti.com/thread/1085372?ContentTypeID=0</link><pubDate>Mon, 20 Jul 2026 03:50:31 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:3b8c9f5f-bd49-4ada-a908-31a03149b93b</guid><dc:creator>JIngXiang Yang</dc:creator><slash:comments>3</slash:comments><comments>https://e2echina.ti.com/thread/1085372?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/tools/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/1085372/ccstudio-theia-ccs-theia-sysconfig-switch-not-working-for-mspm0g3507/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; CCSTUDIO-THEIA&lt;br /&gt;&lt;b&gt;Other Parts Discussed in Thread:&lt;/b&gt; &lt;a href="https://www.ti.com.cn/tool/cn/SYSCONFIG" class="internal-link folder tool" title="Link to Tool Folder" target="_blank"&gt;SYSCONFIG&lt;/a&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;In the SysConfig view of my CCS project, I clicked the &amp;quot;Switch&amp;quot; button to change the device package/part number.

&lt;p data-is-only-node="" data-is-last-node="" data-end="497" data-start="19"&gt;I am an optical design engineer, and we are currently performing system-level efficiency calculations. I would like to ask whether the diffraction efficiency value in the DLP9500 datasheet is the same as the value calculated using the DMD_Diffraction_Efficiency_Calculator. If we are working in the UV wavelength range, does it mean we should use the results from the DMD_Diffraction_Efficiency_Calculator instead of the values provided in the datasheet to calculate efficiency?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
