If no response is received, it may indicate that the HSE firmware encountered a fatal error and entered shutdown mode. In this case, we recommend checking the MU GSR register for diagnostic information.<BR />Possible causes include invalid service parameters, invalid memory addresses, XRDC access violations, ECC errors, clock or initialization issues, resource conflicts, or other fatal HSE internal errors.<BR />To help investigate, please provide the HSE FW version, the specific HSE service being executed, the service descriptor, and the MU status registers (FSR/GSR) when the issue occurs.</P> Wed, 08 Jul 2026 11:54:00 GMT davidtosenovjan 2026-07-08T11:54:00Z https://community.nxp.com/t5/S32K/Pending-HSE-response/m-p/2391879#M59738 <P>I would like to inquire if there have been previous instances where the HSE response remained pending and did not arrive during an OTA update with the S32K312 MCU.</P><P>Additionally, please confirm under what circumstances the HSE response might become pending.</P> Wed, 08 Jul 2026 01:42:55 GMT https://community.nxp.com/t5/S32K/Pending-HSE-response/m-p/2391879#M59738 hjkim84 2026-07-08T01:42:55Z https://community.nxp.com/t5/S32K/Pending-HSE-response/m-p/2392357#M59749 <P>We are not aware of a known S32K312 OTA issue that causes HSE services to remain permanently pending.<BR />In general, every HSE service request should return a response.
