Here are my environment settings:</P><P>I am using RTD version: 4.0.2, with the OStype set to FreeRTOS in the baseNXP module.<BR />Both the FreeRTOS and UART modules are using their default settings.<BR />When I call Linflexd_Uart_Ip_AsyncSend within a task, it triggers the uart_irq_handler. Upon the transmission of the last piece of data,<BR />the Linflexd_Uart_Ip_CompleteSendUsingInterrupts, Linflexd_Uart_Ip_SetInterruptMode, SchM_Enter_Uart_UART_EXCLUSIVE_AREA_02, and OsIf_SuspendAllInterrupts are invoked in the Uart_Irq_handler.<BR />Finally, OsIf_SuspendAllInterrupts calls FreeRTOS's taskENTER_CRITICAL, which triggers configASSERT.</P><P>Could you please help me resolve this issue?<BR />Should I use taskENTER_CRITICAL_FROM_ISR instead of taskENTER_CRITICAL in the Uart_irq_handler?<span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/289306iC9B23D693CAB03AE/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/289307i2BE3B31834D904E7/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 893px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/289309i87848C12C258C0FA/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/289310i55472915030ADB68/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></P> Fri, 19 Jul 2024 06:08:04 GMT https://community.nxp.com/t5/S32G/program-stuck-when-using-S32G-UART-API-with-freertos/m-p/1911882#M8817 Terry_Huang 2024-07-19T06:08:04Z https://community.nxp.com/t5/S32G/program-stuck-when-using-S32G-UART-API-with-freertos/m-p/1911917#M8818 <P>upload the call stack we observed&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 999px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/289320i58B24BBC5CB7AB5C/image-size/large?v=v2&amp;px=999" role="button" title="image.png" alt="image.png" /></span></P><DIV><DIV class="">&nbsp;</DIV></DIV> Fri, 19 Jul 2024 07:07:17 GMT https://community.nxp.com/t5/S32G/program-stuck-when-using-S32G-UART-API-with-freertos/m-p/1911917#M8818 Terry_Huang 2024-07-19T07:07:17Z
