&lt;div&gt;
&lt;div&gt;
&lt;div&gt;1. **TISCI 消息路径**: Sciclient_pmSetModuleState(TISCI_DEV_DPHY_RX0,&amp;nbsp;TISCI_MSG_VALUE_DEVICE_SW_STATE_ON)&amp;nbsp; 走 device_enable() 完整流程&amp;nbsp; &amp;nbsp;(时钟 &amp;rarr; 依赖 &amp;rarr; 电源域 &amp;rarr; MDCTL &amp;rarr; GO) &amp;mdash; 约 10us 内返回 -1。&lt;/div&gt;
&lt;div&gt;2. **直写 PSC 寄存器** (TISCI 失败后):&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- MDCTL26.NEXT=3 (ENABLE) + PTCMD GO &amp;rarr; NEXT 被硬件消费后回退为 0,MDSTAT 不变, PTSTAT 从未置位, 10 万次紧轮询**零过渡态** (从未观察到0x21-0x2B 中间态);&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- MDCTL26.NEXT=1 (SYNC_RESET) &amp;rarr; 同样静默失败;&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- MDCTL26.NEXT=2 (DISABLE) &amp;rarr; 同样。&lt;/div&gt;
&lt;div&gt;3. **FORCE 强制转换** (MDCTL26 bit31, 按 E2E 帖 1408158 的建议):&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;FORCE|SYNC_RESET+GO、FORCE|DISABLE+GO &amp;mdash; FORCE 位回读时已被硬件清除,MDSTAT 仍是 0x0A00。&lt;/div&gt;
&lt;div&gt;4. **LRST 直控位** (MDCTL26 bit8, 不经 FSM/GO 握手): assert&amp;rarr;release 翻转后 MDSTAT26.LRSTZ (bit8) **毫无变化** (保持 0)。健康模块 (LPSC25) 的ctl/stat 始终镜像一致 (0x103/0x1F03)。这表明 PSC 到模块 26 的 slice寄存器通路本身已死 &amp;mdash; 仅 CBASS 总线接口活着 (MDCTL26 可写可读回)。&lt;/div&gt;
&lt;div&gt;5. **防火墙**: MERRPR0/MERRPR1 = 0, GBLSTAT = 0 (清除后); MDCTL26 写入落地 (回读正确), 排除防火墙拦截。&lt;/div&gt;
&lt;div&gt;6. **时钟**: DPHY_RX0 主时钟父节点是 CHIP_DIV1_CLK_CLK (与工作正常的UART0 VBUSP 同源)。无软件可编程的 PHY PLL。&lt;/div&gt;
&lt;div&gt;7. **电源**: VDDA_1P8_CSIRX0 实测 1.792V, VDDA_CORE_CSIRX0 实测 0.848V &amp;mdash;&amp;nbsp; &amp;nbsp;均在标称范围。&lt;/div&gt;
&lt;div&gt;8. **引脚复用**: MIPI RX 差分线为专用引脚 (无 PADCONFIG 表项)。&lt;/div&gt;
&lt;div&gt;9. **外部 TX 状态无关性**: 在外部 MIPI TX 启动前/启动后/不同 CSI 速率 (1700/1200/600 Mbps) 下尝试使能 &amp;mdash; 全部相同失败,排除线态/TX 活动因素。&lt;/div&gt;
&lt;div&gt;10. **模块 25 对照**: LPSC25 (CSI_RX_IF0) 用完全相同的序列任何时刻都能使能并工作 &amp;mdash; 问题唯一指向模块 26。&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;
&lt;div&gt;### 与 E2E 帖 1408158 的关键对比&lt;/div&gt;
&lt;br&gt;
&lt;div&gt;帖 1408158 (AM62A7, 2023) 报告了同类失败 (使能失败、SYNC_RESET 失败、强制转换失败)。TI 当时的内部输入是: &amp;quot;PSC 逻辑在转换前需要 IP 应答。如果到 SYNC_RESET 的转换失败, 说明 IP 不空闲或处于坏状态。&amp;quot;我们的案例比该帖更严重: 那位客户能 DISABLE 但不能 ENABLE。我们**无法通过任何机制向任何方向移动模块 26** &amp;mdash; 包括完全不经 FSM/应答路径的 LRST 直控位。&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;###提问&lt;/div&gt;
&lt;div&gt;1. AM62Ax 是否存在已知硅片勘误 &amp;mdash; DPHY_RX0 (LPSC26) 的 PSC slice 对任何状态转换请求/本地复位控制无响应? 若有, 规避方案是什么?&lt;/div&gt;
&lt;div&gt;2. DPHY_RX0 状态转换是否存在文档未覆盖的 &amp;quot;IP 应答&amp;quot; 前置条件 (例如 DPHY专属的 CTRL_MMR 隔离或本地复位释放, 必须在 PSC 转换前完成)?&lt;/div&gt;
&lt;div&gt;3. 是否有额外的调试寄存器 (MDSTAT/PTSTAT/MERR 之外) 能暴露 PSC FSM拒绝模块 26 转换的原因?&lt;/div&gt;
&lt;div&gt;4. 若为已知问题, 是否有计划在后续 SDK/器件修订中修复? (注: AM62Ax&amp;nbsp;MCU+ SDK 自 2025 年 8 月的 11.01.00.16 后未再更新。)&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;### 环境信息&lt;/div&gt;
&lt;div&gt;- R5FSS0-0 裸机 FreeRTOS 应用, Sciclient_direct_init() (经sciserver/dm_stub 自托管 DM), 自研 SBL 从 QSPI NOR 引导&lt;/div&gt;
&lt;div&gt;- PSC 基址 0x04000000: MDSTAT26 @ 0x0800+0x68 读数 0x0A00;MDCTL26 @ 0x0A00+0x68; PD0 (ALWAYS_ON) PDSTAT = 0x00000301&lt;/div&gt;
&lt;div&gt;- MDCFG26 解码: NUMCLKEN=7, PERMDIS=0, NEXTLOCK=0&lt;/div&gt;
&lt;div&gt;- 相邻模块 25 (CSI_RX_0): MDCTL=0x103 / MDSTAT=0x1F03 (ENABLE, 健康) &amp;mdash;证明编程序列、权限和电源域状态全部正常&lt;/div&gt;
&lt;div&gt;&amp;nbsp;&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;
&lt;div&gt;换板复测问题相同，结果如下&lt;/div&gt;
&lt;br&gt;
&lt;div&gt;1. **MDCFG26=0x11FF 逐位解码** (TRM Table 14-11568):&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- PERMDIS(bit10)=0 &amp;rarr; 未被永久禁用 (推翻早前 PERMDIS=1 误读)&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- NEXTLOCK(bit13)=0 &amp;rarr; MDCTL.NEXT 可写 (无写锁)&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- ASYNC(bit12)=1, PWRDOM=0 (PD0=GP_CORE_CTL, 与 devices.c 一致)&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- NUMCLK/NUMCLKEN/NUMSCRDISBALE=7/7/7 (DPHY 复杂时钟岛)&lt;/div&gt;
&lt;div&gt;2. **完整 TISCI 设备使能流程失败**: `Sciclient_pmSetModuleState(DPHY_RX0,ON)` 走本地自托管 DM 全流程 (时钟配置 + LPSC 依赖 + 电源域 + PSC 转换),ret=-1, 822us 超时, MDSTAT26 全程 0x0a00。&lt;/div&gt;
&lt;div&gt;3. **直写寄存器序列同败**: MDCTL26 写 NEXT=3/1/2 (Enable/SyncRst/Disable)+ PTCMD GO(PD0)。写入确认落地 (R98 探针 rb=0x103), 但:&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- MDSTAT26 恒为 0x0a00, 过渡态 (0x21-0x2B) 一个都没出现;&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- PTSTAT bit0 在紧轮询窗口内从未观测到置位;&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- **NEXT 被硬件清回 0** (C: 循环后清回; D/E: 循环内清回 0x100)。&lt;/div&gt;
&lt;div&gt;4. **MDSTAT26=0x0a00 精确解码** (TRM Table 14-11571): STATE=0(SwRstDisable), MRSTZ(bit10)=0 + LRSTZ(bit8)=0 &amp;rarr; 模块/本地双复位**稳定置位**, MRSTDONE/LRSTDONE=1 &amp;rarr; FSM 干净停在复位静止态, 不是卡在转换中间态。&lt;/div&gt;
&lt;div&gt;5. **对照实验 `[R177-G]` (同域同配置相邻模块)**:&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- m25 (CSI_RX_0, 同 PD0, 同 MDCFG=0x11FF): ctl=0x103 (NEXT=3 **保持**),stat=0x1f03 (ENABLE, 全部复位释放) &amp;mdash; 同一套序列刚成功;&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- m34 (MAIN_IP, DPHY_0 的 LPSC 硬依赖): ctl=0x103, stat=0x1f03 &amp;mdash;&amp;nbsp;ROM 使能后 NEXT=3 一直保持;&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- m26 (DPHY_0): ctl=0x100 (NEXT=0 被回退), stat=0x0a00。&lt;/div&gt;
&lt;div&gt;&amp;nbsp; &amp;nbsp;- 旁证: 成功使能的模块 GO 后 NEXT 从不清零 &amp;rarr; LPSC26 的&amp;quot;NEXT 消费后回退 + 状态不动&amp;quot;是硬件拒绝执行转换的特有行为。&lt;/div&gt;
&lt;div&gt;6. **辅助状态全部干净**: MERRPR0/1=0, GBLSTAT=0, PDCTL0=0x301(ON+EPCGOOD), PDSTAT0=ON &amp;mdash; 无任何 FSM 错误标志。&lt;/div&gt;
&lt;br&gt;
&lt;div&gt;**SDK 侧交叉验证** (本轮新增, rm_pm_hal devices.c/psc.c):&lt;/div&gt;
&lt;div&gt;- 模块号确认: LPSC25=CSI_RX_0 (TISCI_DEV_CSI_RX_IF0), LPSC26=DPHY_0(TISCI_DEV_DPHY_RX0), LPSC34=MAIN_IP &amp;mdash; 与寄存器读数完全吻合;&lt;/div&gt;
&lt;div&gt;- 依赖链: DPHY_0 depends=MAIN_IP(34) (已 ENABLE, 依赖满足);CSI_RX_0 depends=DPHY_0 &amp;mdash; 而 m25 在 m26 未使能时照样 ENABLE &amp;rarr;LPSC depends 是 PM_HAL 软件引用计数, 非硬件 FSM 门控;&lt;/div&gt;
&lt;div&gt;- PM_HAL 使能序列 (依赖&amp;rarr;PD ON&amp;rarr;写 MDCTL&amp;rarr;PTCMD GO&amp;rarr;等 PTSTAT/MDSTAT)与 R177 手动序列等价, 且用同一序列 m25 成功;&lt;/div&gt;
&lt;div&gt;- DPHY 时钟表 7 项中除 MAIN_CLK (常开 CHIP_DIV1) 外均为板级/输出时钟(CSI0_RXCLKP/N 输入脚、TCK、PPI_RX_BYTE_CLK 输出), 无需 PLL 配置,排除时钟父源缺失导致 FSM 拒绝的可能。&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;/div&gt;

&lt;p&gt;1：问题描述：我们的产品使用到了TMS320F28335PGFA芯片，在客户工厂使用时，出现了应用程序被擦除的情况（IAP程序正常），最终导致产品不工作。重新烧录应用程序后，产品恢复正常。&lt;/p&gt;
&lt;p&gt;2：问题定位：软件定位到是&lt;span data-type="leaf"&gt;存储在FLASH的C扇区的数据擦除，怀疑是程序主动擦除的，程序的主动擦除是根据存储在RAM里的一个标志位决定是否执行程序擦除；在&lt;/span&gt;&lt;span data-type="leaf"&gt;执行擦除时，需从FLASH地址中读取更新指令，&lt;/span&gt;&lt;span data-type="leaf"&gt;怀疑RAM中的标志位出现异常或FLASH读取指令时出现异常。&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span data-type="leaf"&gt;3：硬件定位：通过示波器查看芯片内核电压与XRS引脚的下电时序，并未出现XRS的信号超前内核电压掉电。上电时序内核电压也提前 VDDIO 电压上电。产品添加了EMC的防护和CE认证。&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span data-type="leaf"&gt;4：做过的排查：因怀疑芯片可能受到强电磁干扰导致上述问题，采用芯片（受试芯片还包括电源芯片：TPS767D301MPWPREP）上方紧贴导线，并在此导线上施加190A的脉冲电流，模拟芯片受到电磁干扰，多次测试均未复现程序丢失情况。&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span data-type="leaf"&gt;请问此问题会是哪些原因导致的？&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>TMS320F28P650DK: 用一个信号，三个ADC采样模块，同一个SOC采集到的值存在差异</title><link>https://e2echina.ti.com/thread/1087285?ContentTypeID=0</link><pubDate>Fri, 31 Jul 2026 06:15:27 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:c56f69f9-a8c4-484a-9fcd-2492ff6ce55d</guid><dc:creator>sam duan</dc:creator><slash:comments>5</slash:comments><comments>https://e2echina.ti.com/thread/1087285?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/processors/f/processors-forum/1087285/tms320f28p650dk-adc-soc/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/TMS320F28P650DK" class="internal-link folder product" title="Link to Product Folder" target="_blank"&gt;TMS320F28P650DK&lt;/a&gt;&lt;br /&gt;&lt;/p&gt;&lt;p&gt;光伏逆变器产品，采用TMS320F28P650DK，ADC-A ,ADC-B,ADC-C采集同一个1.5V信号，计算出的数据幅值不一样。&lt;/p&gt;
&lt;p&gt;原理图如下：1.5V模拟电压送到 A14 B14 C14 ,三个模块同时采集一个模拟信号。&amp;nbsp;&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/120/6098f4b9_2D00_8e42_2D00_4c62_2D00_9949_2D00_c00183e01ffd.png" alt="6098f4b9-8e42-4c62-9949-c00183e01ffd.png" data-temp-id="6098f4b9-8e42-4c62-9949-c00183e01ffd.png-38122"&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;测试结果：输入信号是同一个1.5V信号，使用三个ADC通道采样后的结果不一致，C14通道采样结果相对差一些&lt;/p&gt;
&lt;p&gt;&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/120/6cdde3ceaa652de4f586a64b7a0bd07b.png" alt="6cdde3ceaa652de4f586a64b7a0bd07b.png" data-temp-id="6cdde3ceaa652de4f586a64b7a0bd07b.png-67950"&gt;&lt;/p&gt;
&lt;p&gt;ADC 模块供电原理图如下：三个采样模块采用同一个电源和地,供电采用3.3V 的LDO(REF3030AIDBZR)降压到3V&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;

&lt;p&gt;将问题问询了 ai， ai 说：&lt;/p&gt;
&lt;p&gt;a. 在动态任务中，如果没指定&amp;nbsp;.stackHeap，则栈通常来自：&lt;strong dir="ltr"&gt;默认堆 heap，也就是 SYS/BIOS 的默认动态内存池。&lt;/strong&gt;&lt;/p&gt;
&lt;div dir="ltr"&gt;具体来源一般是：&lt;/div&gt;
&lt;ol dir="ltr" start="1"&gt;
&lt;li dir="ltr"&gt;如果配置了 &lt;code dir="ltr"&gt;Task.defaultStackHeap&lt;/code&gt;，则从该 Heap 分配；&lt;/li&gt;
&lt;li dir="ltr"&gt;否则从 &lt;code dir="ltr"&gt;Memory.defaultHeapInstance&lt;/code&gt; 分配；&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;---&lt;/p&gt;
&lt;p&gt;b. 在静态任务中，如果没指定 .stackSection，则其&lt;span data-spm-anchor-id="a2ty_o01.29997173.0.i11.732155fbxSYtxq"&gt;来自&lt;/span&gt;编译期静态分配的 RAM，通常位于 &lt;code dir="ltr"&gt;.bss&lt;/code&gt;、&lt;code dir="ltr"&gt;.far&lt;/code&gt;、&lt;code dir="ltr"&gt;.ebss&lt;/code&gt; 或你指定的 task stack section。&amp;nbsp;&lt;/p&gt;
&lt;p&gt;---&lt;/p&gt;
&lt;p&gt;请问上述说法正确吗？如果我想控制不同的静态任务的任务堆栈的位置，是不是只需修改 .stackSection 并使用 Program.sectMap[] 语句改变段位置即可？&lt;br&gt;---&lt;/p&gt;
&lt;p&gt;此外在其它示例工程的 cfg 中看到了这样一条语句，这是代表将所有任务的栈空间都分配到 &lt;span&gt;L2SRAM&amp;nbsp;&lt;/span&gt;这个段上吗？&lt;/p&gt;
&lt;p&gt;Program.sectMap[".far:taskStackSection"] = &amp;quot;L2SRAM&amp;quot;;&lt;/p&gt;

The FPGA is configured as a CSI interface, and its VCCO needs to be set to 1.2V. The VCC voltage of the CSI in TDA4 is 1.8V. Can the CSI interface of FPGA and TDA4 be directly connected?&lt;br&gt;I understand that the two can be directly connected. Because both chips comply with the MIPI DPHY v1.2 standard. The MIPI LP level defined in this standard is 1.2V.&lt;/p&gt;
