I followed the instructions you provided, but it appears that the current webpage structure may have changed, and I was unable to find the entry points you described. Specifically: 1. When opening `ticsc.service-now.com/csm`, the page remains stuck in a loading/redirecting state and does not display the "Request a New Support" or "Submit an Application for the Family" buttons you mentioned. 2. I also tried navigating through the "Support & Quality" section on TI.com.cn, but still could not find a submission path that matches your description. Could you please provide an updated guide or a direct link? For example, is there a way to submit a quality-related case directly through my TI account page? Or is there an email address I can use to send the X-ray inspection results and a description of the issue to the relevant team? I look forward to your further guidance. Thank you.https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1087272/am2432-continuous-frame-loss-is-observed-with-the-enhanced-link-function-enabled-for-am2432-ethercat-pru/3914203Tue, 04 Aug 2026 08:07:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:42364288-cdb0-4ff0-a7c8-3009acde2e0bAaron Thomas你好， 这是否与 “回复：AM2434：AM243增强型链路通信的Ethercat问题” 重复？ 问候， 亚伦ECTEhttps://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1087513/ucc28711-internal-lead-frame-protrusions/3914202Tue, 04 Aug 2026 07:06:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:493f7ff1-133d-4e03-ae6e-78c7ff19e6e4FRANK1The TI E2E Forum is designed to address technical issues customers encounter while designing with TI products.

As shown in the attached X-ray images, there appear to be internal lead-frame protrusions on the side of the body of the device. These protrusions extend outward from the main lead-frame structure and are visible on both the top and side views under inspection. We have highlighted the areas of concern in the images for reference. Could you please help confirm: Are these protrusions a normal characteristic of the lead-frame design for this device? Could they potentially impact the mechanical or electrical reliability of the part, such as the risk of short circuits or die attach integrity? Is there any known process variation that could cause such features, and do they fall within TI's standard acceptance criteria? Any clarification or guidance would be greatly appreciated.

When the Enhanced Link function is enabled, continuous frame loss may occur probabilistically after power cycling the device (the Beckhoff master cannot receive the returning data frames). This frame loss issue does not occur when the Enhanced Link function is disabled. Investigation results are listed below: 1、When the problem occurs, the Ethernet LED remains steadily on, which means the PHY link has been established. 2、We read the ESC Port Control register (0x100) and Port Status register (0x110). The value of Port Status register 0x110 is 0x5501, indicating that the port link is not up and the port is not opened. This suggests an issue with PRU processing.AM2434AM2432https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1086293/tms320f28335-f28335mcbsp-spi/3911042Mon, 27 Jul 2026 04:30:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:6270d3ce-9509-4e4f-9bc3-55ed78bdba4cDaniel您好 https://dev.ti.com/tirex/explore/node?isTheia=false&node=A__AA5CUK4JS.MUNHzyYDDXeg__C2000WARE__1kRFgrO__LATEST 请您参考官方给出的历程。 TMS320F28335：McBSP 配置处理 SPI 速度问题 - C2000 微控制器论坛 - C2000 ™ ︎ 微控制器 - TI 端对端支持论坛 相关帖子说明。请您参考。https://e2echina.ti.com/support/microcontrollers/other/f/other-microcontrollers-forum/1086300/tms320f28335-tms320f28335-mcbsp-spi/3911041Mon, 27 Jul 2026 04:20:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:9082931f-1f63-4473-9aa3-d0ecf49c0cd3Alice您好， 请参考设计手册 TMS320x2833x, TMS320x2823x Technical Reference Manual 的“Table 12-16.
