hi, 請問TC397 CPU看門狗二次重設後,一直處於重設狀態,不再重啟。這是什麼原因導致的? /* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!! * Enable the watchdogs and service them periodically if it is required */ // //IfxScuWdt_disableCpuWatchdog(IfxScuWdtgetCIfxScuWdt_disableCpuWatchdog(IfxScuW tyWatchdogPassword()); IfxScuWdt_changeCpuWatchdogReload(IfxScuWdt_getCpuWatchdogPassword() , REL_VAL); IfxScuWdt_serviceCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword()); /* Wait for CPU sync event */ IfxCpu_emitEvent(&g_cpuSyncEvent); IfxC_wawaity&g_

Kindly refer to this Knowledge Base Article (KBA) to verify if it addresses the same question as yours. https://community.infineon.com/t5/Knowledge-Base-Articles/Why-AURIX-TC233-is-going-into -power-on-re...

 

在第一次SMU復歸被請求時,將設置一個內部標誌。如果在內部標誌已經設定的情況下SMU再次請求第二次復位,就會發生雙SMU復位事件,並自動產生永久重設請求。只有透過系統重設或設定了位元SMU_WDTSCON1.CLRIRF且位元SMU_WDTSCON0.ENDINIT也已經設定時,內部標誌才會被重設。正確服務WDT不會自動清除此標誌。

Reference: Section 9.1.3.3.3 "Prevention of Double SMU Resets" in the document named "aurixtc3xx_um_part1_v2.0.pdf."
