If it’s not meet as per setting voltage at tester (LLimit vs ULimit) board will be failed. Refer to the below test log. This is requested by customer and one of the most important parameters load into our FCT tester. Is it simply just a measure of deviation in the output voltage of your converter during a transient event? Yes.https://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1693206/uc2843-uc2843d8tr-ti66m-body-marking---functional-failure-with-higher-transient-response-voltage-deviation/6525356Thu, 29 Oct 2026 18:44:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:461beafc-70a9-4424-a791-d5ff2bcfe946Adhvaidh AravindHi Amirul, Thanks for reaching out via E2E. I understand you have already opened a formal investigation through our Customer Quality/Product Returns (CPR) process (CPR261155211). Because you have already submitted this for formal analysis, the most effective way to resolve your questions is to continue working directly through that support ticket. Our quality and engineering teams are best positioned to review the specific lot-traceability data for the "TI66M" marking, compare it against your "good" lots (TI62M, TI67M, TI68M), and provide the definitive root cause and disposition guidance you need . I don't have access to the CPR system and I am not sure if you have provided this information already, but could you please send a picture of the top-side marking of your device? Also, could you explain what transient response voltage deviation test is, and what voltage it is measuring? Is it simply just a measure of deviation in the output voltage of your converter during a transient event? Thanks. Best, Adhvaidhhttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1693523/am6442-yocto-ti-sdk-packages-fail-to-be-fetched/6524572Thu, 29 Oct 2026 05:30:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:13d739b2-c7f2-461a-8c53-91ded979454aVinuchandran A VHi, This is a known issue with git.ti.com at the moment and the IT Infra team is still working on it. Until it's fixed, you'll have to rely on the pre-seed workaround. A default clone sends one very large request listing all refs, and the server rejects it with HTTP 501: error: RPC failed; HTTP 501 curl 22 The requested URL returned error: 501 fatal: error reading section header 'shallow-info' Small requests, such as git ls-remote or a single-branch clone, work fine. BitBake’s git fetcher runs git clone --bare --mirror , which asks for every ref, so it hits the failure. Switching the URL scheme or git protocol version won’t help, and the server isn’t rejecting --bare itself. Workaround: pre-seed the BitBake download cache BitBake checks DL_DIR/git2/ before fetching. If the pinned SRCREV is already there, it skips the network. You can fill that cache yourself with a single-branch clone, which works, and leave the recipe unchanged. 1. Find the cache directory BitBake expects for the recipe: bitbake -e | grep ^GITDIR It will look like /git2/git.ti.com.git. .git. 2. Remove any partial or failed download at that path: rm -rf 3. Create the bare clone there, using the branch named in the recipe’s SRC_URI: git clone --bare --single-branch --branch \ https://git.ti.com/git/ / .git 4. Check that the recipe’s SRCREV is in the clone: git -C cat-file -e ^{commit} && echo OK If this fails, the commit is on a different branch. Repeat step 3 with the right branch, or fetch just that ref with git -C fetch origin . Avoid git fetch --all and --tags, which send the large request that fails. 5. Re-run the build: bitbake Repeat this for every repo that fails with the 501, one per recipe. Please try this out as a temporary hack.

Issue Summary Affected device: UC2843D8TR Suspect body marking: TI66M Good body markings: TI62M, TI67M, TI68M Observed failure rate: Currently observed on all evaluated TI66M units. Failure detected during Functional Circuit Test (FCT). FCT Results Parameter Suspect Unit (TI66M) Good Unit Transient Response Voltage Deviation 6.2 V 2.8 V Product Acceptance Limit 4.0 V 4.0 V Result FAIL PASS Investigation Good and failed units were evaluated under identical test conditions. Failures are currently correlated to TI66M body marking lots. Material has been segregated and blocked from production pending investigation. Engineering analysis report has already been submitted through TI CPR process (CPR261155211). Question, 1.Although the transient response voltage deviation is not a datasheet parameter, what internal device characteristics could cause one lot (TI66M) to consistently show higher deviation than other body markings? 2.Have there been any known process changes, fab changes, assembly changes, test flow changes, or material changes associated with lots represented by body marking TI66M? 3. what shall be the disposition for this failed part? 4.Why TI66M behaves differently from TI62M/TI67M/TI68M.UC2843https://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1691236/uc2845aq-part-uc2845aq-technical-inquiry/6521265Mon, 26 Oct 2026 16:01:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9d2d8ada-e50e-4c31-9baa-c00e535568d0Adhvaidh AravindHi Zoltan, Thanks for reaching out via E2E.

Our technical team has reviewed the document, and we appreciate the thorough preliminary testing you have already conducted. The details you provided—including the 70% failure rate (273/490 pcs) , the successful A-B-A swap test confirming the issue follows the IC, and the Lot Trace Code (5186644WCW) —are exactly what the manufacturer needs to trace the manufacturing batch records. Regarding RMA, please reach out to your local FAE team and quality team, (based on field team judgment) to formally submit this case to the manufacturer's Failure Analysis (FA) laboratory and get their official assessment on the internal voids, we will require the original X-ray images or inspection reports referenced in your form. Could you please reply with the following attachment(s)? High-resolution X-ray image files (or video captures/reports) showing the internal voids/bubbles within the components. (Optional but highly recommended) Any specific programming logs or error codes generated during the failure.

Please advise RMA-2026-13429 / FA and Credit request Could you please assist us on this material issue shared by customer? Per customer: We are currently investigating an intermittent failure during the programming process of one of our products. During the failure analysis, through X-ray inspection, we identified what appear to be internal voids/bubbles within the component. This condition has been observed in components associated with the reported failure. Could you please support us by coordinating with the component manufacturer to confirm whether this condition is considered acceptable, whether there is any defined specification or limit for this type of voiding, and what manufacturing or material-related conditions could cause it? Our main objective is to determine whether this condition could be causing or contributing to the intermittent behavior we are observing. We would appreciate the manufacturer’s support in reviewing the X-ray images and providing a technical assessment regarding the possible relationship between the voids and the intermittent failure.Industrial AutomationTM4C129ENCPDThttps://e2e.ti.com/support/site-support-group/site-support/f/site-support-forum/1687353/tpsm33615-how-to-calculate-the-effective-capacitance-value-for-output-capacitor/6510761Wed, 14 Oct 2026 15:58:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:9ad336f9-45a3-4da8-a721-a4af0de08ec2Frank De StasiHello That value is found empirically based on bench testing and simulation.
