Can it achieve a higher inductance under the same core volume and thus improve power density?</div> </div> <div> <div>In Lab 3, the PH1 branch operates normally, yet the PH2 branch suffers intermittent drive loss. What are the potential root causes for this fault? Previously, the PFC performance was excellent with an input voltage of 90 V, yielding a power factor above 0.99. The missing drive fault on PH2 only emerged after the input voltage was raised to 200 V.</div> </div> <div> <div>After proceeding to Lab 4, the Hall-effect sensor on the PH2 branch was damaged. Following replacement of this Hall sensor, the maximum achievable power factor dropped to merely 0.91, and the PH2 drive becomes lost even at 90 V input.</div> </div> <div> <div>Is it feasible to disconnect one winding of the coupled inductor to test a single branch independently? Are there published papers validating the design of this coupled boost inductor? Can we substitute the coupled inductor with two discrete inductors for subsequent testing? I have exhausted troubleshooting ideas and have no clear direction for further debugging. Your prompt assistance would be highly appreciated.</div> <div><img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/96/6811.image.png" alt="image.png" data-temp-id="image.png-13655"></div> <div>&nbsp;</div> <div><img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/96/56804.image.png" alt="image.png" data-temp-id="image.png-80270"></div> </div><div style="clear:both;"></div>https://e2echina.ti.com/thread/1076768?ContentTypeID=0Wed, 03 Jun 2026 01:49:40 GMT91561404-af28-475a-b96b-cb6cbaadd097:7c1d02ee-501d-4634-87ce-03fd1124521eJiatong Zhan2https://e2echina.ti.com/thread/1076768?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1076768/tidm-02002-tidm-02002/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/tool/cn/TIDM-02002" class="internal-link folder tool" title="Link to Tool Folder" target="_blank">TIDM-02002</a><br /></p><p>各位TI的工程师，我们公司最近有个双向DC/DC的项目，现在对比DAB、CLLLC等方案，在TI参考设计栏目找到了一些资料，请问能提供一些仿真文件吗？</p><div style="clear:both;"></div>https://e2echina.ti.com/thread/1076697?ContentTypeID=0Mon, 01 Jun 2026 00:46:41 GMT91561404-af28-475a-b96b-cb6cbaadd097:d53726b1-2bc9-4415-9714-6f05a443bfbfXu Large5https://e2echina.ti.com/thread/1076697?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1076697/tcan1146-q1-tcan1146/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/product/cn/TCAN1146-Q1" class="internal-link folder product" title="Link to Product Folder" target="_blank">TCAN1146-Q1</a><br /></p><p>您好，我有两个TCAN1146的使用问题需要咨询：</p> <p>1.控制器下电时，唤醒芯片通过SPI指令设置为sleep模式，INH拉低后，此时CAN总线上一直有非唤醒报文或者唤醒报文，则总线INH会被拉高，原因是什么呢。</p> <p>2.CAN总线上现在有两个唤醒CAN，下电时，将一个控制器的唤醒CAN设置为sleep模式，INH会正常拉低，但是休眠后，无法再次唤醒。只有经过一次断总电，才能重新进行唤醒。该问题原因可能是什么？进入了故障模式？如果是进入故障模式，需要如何处理才能不断总电就可以被唤醒？</p> <p>以上问题困扰我好几天了，希望可以得到快速的回复，十分感谢。</p><div style="clear:both;"></div>https://e2echina.ti.com/thread/1076414?ContentTypeID=0Sat, 30 May 2026 07:38:11 GMT91561404-af28-475a-b96b-cb6cbaadd097:4f370b5b-3a45-41e6-9c88-6b82ce3341d4blank hu1https://e2echina.ti.com/thread/1076414?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1076414/rm57l843-we-are-going-to-use-this-chip-can-you-help-to-release-the-related-software-development-kit-and-software-user-guide-thanks/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/product/cn/RM57L843" class="internal-link folder product" title="Link to Product Folder" target="_blank">RM57L843</a><br /></p><h2>we are going to use this chip , can you help to &nbsp;release the related &nbsp;software developmentkit &nbsp;and &nbsp;software user guide ,</h2> <p>first we wants to bootup RM57L843 EVK(Which we are desgining the hardware now )</p> <p>pls&nbsp; kindly help to release the related software developmentkit and user guide ,thanks&nbsp;</p><div style="clear:both;"></div>https://e2echina.ti.com/thread/1075607?ContentTypeID=0Tue, 26 May 2026 10:57:21 GMT91561404-af28-475a-b96b-cb6cbaadd097:55cf14a4-098a-4f8a-ad7e-658c7b5db025Feiyang Zhang2https://e2echina.ti.com/thread/1075607?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1075607/am2754-q1-am275x-uart0-pmic-resetstatz-bootmode/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/product/cn/AM2754-Q1" class="internal-link folder product" title="Link to Product Folder" target="_blank">AM2754-Q1</a><br /></p><p>器件型号：<br>AM275x / AM2754<br><br>PMIC：<br>与 AM275x EVM 上使用的 PMIC 型号一致<br><br>板卡：<br>AM275x 自制硬件板<br><br><br>问题概述：<br><br>我们正在调试一块基于 AM275x 的自制板。该板使用的 PMIC 型号与 AM275x EVM 一致，当前配置为 UART0 启动，但上电后 UART0 没有任何输出。<br><br>同时我们观察到 BOOTMODE 引脚电平和 RESETSTATZ 行为异常。<br><br>在我们的自制板上，BOOTMODE 高电平只有约 1.3 V，理论上应为 1.8 V。断开 ADC 芯片后无变化。但是断开 AM275x SoC 后，BOOTMODE 高电平恢复到 1.8 V。<br><br>对比 AM275x EVM，EVM 上 BOOTMODE 信号通过缓冲器/收发器接入 SoC，并且缓冲器受 RESETSTATZ 信号控制。我们可以在 AM275x EVM 上测到正常的 RESETSTATZ 复位波形，但在我们的自制板上没有测到预期的 RESETSTATZ 波形。<br><br>由于 PMIC 型号与 AM275x EVM 一致，因此我们目前重点排查自制板与 EVM 在 PMIC 外围电路和启动时序上的差异。我们怀疑问题可能与 PMIC 外围使能电路、VIO 供电来源、电源时序、RESETSTATZ 行为、BOOTMODE 缓冲器/控制逻辑有关，而不是 PMIC 型号选择错误。<br><br><br>测试结果：<br><br>1. 输入电源<br><br>设备上电后，输入电源为 12 V。<br><br>测得输入电流约为 8&ndash;11 mA，电流稳定。不同 BOOT 引脚电阻焊接配置下，电流会有轻微变化。<br><br>2. 常供电电源轨<br><br>宽压转 5 V 的 DCDC 输出正常。<br><br>以下常供电电源轨测量正常：<br><br>SOC_VDDSHV_CANUART = 1.8 V<br>VDD_CANUART = 0.85 V<br><br>3.

PMIC 才能启动<br><br>如果是后者，就会形成类似循环依赖：<br><br>PMIC 不启动<br>&rarr; SoC 不工作<br>&rarr; PMIC_LPM_EN0 不拉高<br>&rarr; PMIC 仍然无法启动<br><br><br>希望 TI 协助确认的问题：<br><br>1. 我们的自制板使用了与 AM275x EVM 相同型号的 PMIC。请问 TI 能否确认 EVM 上 PMIC 外围电路中，哪些部分是 AM275x 正常启动所必须的？特别是 PMIC 的 VIO、使能控制逻辑以及相关 U15/Q1 电路，是否必须由常供电电源轨供电？<br><br>2. 在 AM275x EVM 上，PMIC 启动、PMIC_LPM_EN0 和 RESETSTATZ 之间的预期关系是什么？PMIC_LPM_EN0 在 PMIC 电源时序完成前保持低电平是否正常？还是外部 PMIC 电路应当在 SoC 驱动该信号之前就能独立启动？<br><br>3. 如果 PMIC_LPM_EN0 在 PMIC 启动前保持低电平，硬件设计上是否需要提供外部上拉或默认使能路径，让 PMIC 能先启动？<br><br>4. 在 AM275x EVM 上，BOOTMODE 信号通过缓冲器/收发器接入 SoC，并受 RESETSTATZ 控制。这个缓冲/控制方案是否是必须或推荐的？是否用于避免 SoC 在复位未释放或电源未完整建立时拉低 BOOTMODE 引脚？<br><br>5. 我们测得 BOOTMODE 高电平只有约 1.3 V，断开 SoC 后恢复到 1.8 V。这是否说明 SoC 因为部分电源轨未上电或时序错误，导致 BOOTMODE 引脚被内部钳位、漏电或反向供电？<br><br>6. 对于这种情况，推荐的硬件调试顺序是否应该是：<br><br>强制 PMIC 使能<br>&rarr; 确认所有 PMIC 输出电源轨正常<br>&rarr; 检查 RESETSTATZ 波形<br>&rarr; 检查 BOOTMODE 引脚电平<br>&rarr; 再检查 UART0 启动输出<br><br><br>补充说明：<br><br>UART0 的物理连接已经检查过，暂不认为是串口线或 UART 接错的问题。<br><br>当前更主要的症状是：板子似乎没有进入正常启动状态，因此 UART0 没有任何启动输出。<br><br>希望 TI 能帮助确认 AM275x 的 PMIC 启动时序、PMIC_LPM_EN0 的作用，以及 EVM 上 BOOTMODE 缓冲器和 RESETSTATZ 控制逻辑是否建议在自制板中参考实现。</p> <p><img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/96/0081.image.png" alt="image.png" data-temp-id="image.png-34935"></p> <p><img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/96/8311.image.png" alt="image.png" data-temp-id="image.png-110987"></p><div style="clear:both;"></div>https://e2echina.ti.com/thread/1072145?ContentTypeID=0Wed, 06 May 2026 15:28:32 GMT91561404-af28-475a-b96b-cb6cbaadd097:f98a78e0-a1b9-4a06-a735-2ec309a80c58biza inc2https://e2echina.ti.com/thread/1072145?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1072145/mspm0-sdk-mspm0g3507-dma/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/tool/cn/MSPM0-SDK" class="internal-link folder tool" title="Link to Tool Folder" target="_blank">MSPM0-SDK</a><br /><b>Other Parts Discussed in Thread:</b> <a href="https://www.ti.com.cn/product/cn/MSPM0G3507" class="internal-link folder product" title="Link to Product Folder" target="_blank">MSPM0G3507</a></p><p>HI，我在基于MSPM0G3507的串口+DMA实现不定长数据的收发，由于MSPM0G3507的寄存器特殊性，当使用DMA时，因为DMA及时半空FIFO所以超时中断无法触发，如果引入定时器轮询会浪费外设的同时效率不高，频繁的接收中断也会拉低CPU的效率。</p> <p>我看到并参考：<a href="https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/1220244/faq-uart-rx-ms-level-timeout-realization-based-on-event-for-mspm0?tisearch=e2e-sitesearch&amp;keymatch=UART%20timeout%20MSPM0">https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/1220244/faq-uart-rx-ms-level-timeout-realization-based-on-event-for-mspm0?tisearch=e2e-sitesearch&amp;keymatch=UART%20timeout%20MSPM0</a> 来进行设计，但是发现偶尔会出现字节多收，理论上此拓扑应该能行的通，但是我试验多次，发现一旦数据多了还是会多收字节，表现为DMASZ的数量跟实际发送不一致。</p> <p>对于MSPM0G3507的架构特殊性，我严重怀疑TI的芯片设计是否有用过串口。</p> <p>此问题依然存在，最后我只能使用串口中断+超时中断，使用仅仅4字深的FIFO来接收数据。</p> <p>各位如果有更好的建议，还请让我知道，谢谢！</p><div style="clear:both;"></div>https://e2echina.ti.com/thread/1071472?ContentTypeID=0Fri, 01 May 2026 03:10:08 GMT91561404-af28-475a-b96b-cb6cbaadd097:f911ce41-b4e6-4837-87b7-39536e0a35c5Bo Zhao1https://e2echina.ti.com/thread/1071472?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1071472/tidm-02013-tidm-02013/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/tool/cn/TIDM-02013" class="internal-link folder tool" title="Link to Tool Folder" target="_blank">TIDM-02013</a><br /></p><h2>我们想要两套TIDM-02013进行学习，查找你们商城没有成品进行购卖的，不知道能否定制两套。</h2><div style="clear:both;"></div>https://e2echina.ti.com/thread/1067656?ContentTypeID=0Fri, 10 Apr 2026 02:46:47 GMT91561404-af28-475a-b96b-cb6cbaadd097:cfac3f7f-b3f6-4346-aa9b-51f463a72b47tang yuanzheng2https://e2echina.ti.com/thread/1067656?ContentTypeID=0https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1067656/tda4vm-inquiry-about-online-debugging-support-for-dccsetup_2023_10_10-exe-and-alternative-isp-tuning-tools/rss?ContentTypeId=0<p><b>Part Number:</b> <a href="https://www.ti.com.cn/product/cn/TDA4VM" class="internal-link folder product" title="Link to Product Folder" target="_blank">TDA4VM</a><br /></p><p data-spm-anchor-id="5176.28103460.0.i17.6fd51db8rmJD5a">Hi TI Team,</p> <p data-spm-anchor-id="5176.28103460.0.i16.6fd51db8rmJD5a">I&rsquo;m currently working with the TDA4VM ISP pipeline and using the <strong>DCCSetup_2023_10_10.exe</strong> tool to generate DCC configuration files for image tuning.</p> <p data-spm-anchor-id="5176.28103460.0.i19.6fd51db8rmJD5a">I have two questions:</p> <ol style="list-style-type:none;"> <li style="list-style-type:disc;"> <p data-spm-anchor-id="5176.28103460.0.i21.6fd51db8rmJD5a"><strong>Does DCCSetup_2023_10_10.exe support online (real-time) debugging?</strong><br>Specifically, can I adjust ISP parameters (e.g., GLBCE, noise reduction, color correction) in real time while the system is running, and see the changes reflected immediately in the output video stream?</p> </li> <li style="list-style-type:disc;"> <p data-spm-anchor-id="5176.28103460.0.i20.6fd51db8rmJD5a"><strong>Are there other recommended tools or methods for online ISP tuning on TDA4VM?</strong><br>I&rsquo;ve heard about the TI Image Tuning Tool (ITT) and <code>ti_tuning_app</code>, but I&rsquo;m not sure if they are compatible with this version of DCCSetup or the latest Processor SDK (e.g., PSDK 8.x or 9.x).
