Sbc_fs26_InitDevice(); RTD function failed during Initialisation

Kazarian — Tue, 17 Sep 2024 09:19:47 GMT

Hello,

We use FS2600 with S32K3 on our design, SDK ver 4.0.0. and S32DS ver 3.5 Build id: 240726, update 13. FreeRTOS is used as OS.

During initialisation , this code is called:

Std_ReturnType initFs26Driver() { Std_ReturnType retVal = E_NOT_OK; /* Initializes the FS26 driver */ retVal = Sbc_fs26_Init(&Sbc_fs26_xConfig_BOARD_InitPeripherals); if (retVal != E_OK) { return retVal; } /* Configures the device */ retVal |= Sbc_fs26_InitDevice(); if (retVal != E_OK) { return retVal; } /* Fault Error Counter should decrease to zero */ uint8 u8FaultErrorCounterValue = 0U; retVal |= Sbc_fs26_GetFaultErrorCounterValue(&u8FaultErrorCounterValue); if ((retVal != E_OK) || (u8FaultErrorCounterValue != 0U)) { return retVal; } /* Sbc device should be in FS_STATES_FS0B_ASSERT */ Sbc_fs26_RxFrameType rxData = {0}; retVal |= Sbc_fs26_ReadRegister(TRUE, SBC_FS26_FS_STATES_ADDR, &rxData); if((retVal != E_OK) || ((rxData.u16ReadData & SBC_FS26_FS_FS_STATES_MASK) != SBC_FS26_FS_FS_STATES_FS0B_ASSERT)) { return retVal; } return E_OK; }

Function Fails on Sbc_fs26_InitDevice(); specifically on Sbc_fs26_WaitInitFSClosed() -> Sbc_fs26_WaitInitFSClosed().

InitFS is not closed and the Sbc_fs26_GetDeviceState return FS_STATES_INIT_FS, as shown in image DeviceStateisInitFs.JPG.

attached the used configuration. can you please tell me why is this failing ?

Best regards.

During INIT phase you need refresh WD to decrease fault error counter into zero then close it,can you please verify your WD feeding wrong or correct?

Hello @guoweisun

im using the RTD APIs, the function from the RTD : Sbc_fs26_InitDevice(); already implement the logic you mentioned, however the

/* Close initialization phase by sending first watchdog refresh. */ eReturnValue = Sbc_fs26_WdRefresh();

is not called, and the Sbc_fs26_WaitInitFSClosed(); return a status error 0x1. could it be a wrong config ?

I am not software engineer here I only support FS26,for the FS26 enter into normal mode steps please see below picture,you can match the drive step by step to verify whether it works or not.
