Presented driver is not AUTOSAR nor ISO26262 compliant. This driver package * needs so-called MPC5744P Basic software drivers, which present the basic layer * for this application. * * The key features of this package are the following: * - Offer driver allowing to write and read into and from PwSBC registers * - Switch PwSBC modes (low power, normal etc.) * - Treat all interrupt sources (events) * - Supervise voltages presented in the PwSBC interface * * For more information about the functions and configuration items see these documents: * ******************************************************************************* * * @attention * *******************************************************************************/ /*================================================================================================== * Project : FS65xx * Platform : MPC574xP * Dependencies : MPC574xP - Basic SW drivers. * All Rights Reserved. ==================================================================================================*/ /*================================================================================================== Revision History: Modification This function Author (core ID) Date D/M/Y Name Description of Changes B35993 / BRNY001 18/08/2015 ALL Driver ported from MC33908 BRNY001 30/10/2016 FS65_ProcessSPI Added missing registers (WU_source, Diag_Vcore, Diag_vcca) BRNY001 04/10/2017 LDT related functions Bug correction --------------------------- ---------- ------------ ------------------------------------------ ==================================================================================================*/ #include "typedefs.h" #include "FS65xx_driver.h" #include "FS65xx.h" #include "sbc_65xx.h" #include "SpiIf.h" #include "common.h" struct { uint32_t writeCmd; ///last write command uint32_t readCmd; ///last read command uint32_t stateSPI; ///actual state of the state machine Status_32B_tag statusPwSBC; ///actual PwSBC status uint32_t response; ///last PwSBC response uint32_t FSdelayDisabled; ///disables delay 3.5 us after a secure command, 1 - disabled, 0 - enabled } SPIstruct; struct { uint32_t WD_answer; ///current content of the WD_answer register register32_struct currentLFSR; ///last LFSR state } PITstruct; /*================================================================================================== / Global Variables *==================================================================================================*/ uint8_t FS65_Error = FS65_ERROR_OK; /*==================================================================================================* * User-Defined Initial Values for FS65xx registers * *==================================================================================================* * Fill-in this table with the initialization values for the INIT registers * * Don't bother with the secured bits, they are comuted by the initialization functions * *==================================================================================================*/ FS65_RegVal_struct FS65_Registers_InitValues = { 0x00, // INIT_VREG; 0x43, //0x41, // INIT_WU1; io_0 up and high, io_4 any edge 0xC0, //0x40, // INIT_WU2; io_5 any edge 0x00, // INIT_INT; 0x00, // INIT_INH_INT; 0xF4, // CAN_LIN_MODE; CAN in Normal mode 0x60, // INIT_FS1B_TIMING; 0x00, // INIT_SUPERVISOR; 0x10, // INIT_FAULT; //0x4D, // INIT_FSSM: IO_23 is fail-safe 0x00, // INIT_FSSM: IO_23 not fail-safe 0x10, // INIT_SF_IMPACT; //(WD_WIN_4 << 4), // WD_WINDOW;0x30 // (WD_WIN_128<<4), (WD_DISABLE<<4),//将喂狗的时间由64-128改为32-64ms 0xB2, // WD_LFSR; 0x00, // INIT_WD_CNT; 0xE0, // INIT_VCORE_OVUV_IMPACT; 0xE0, // INIT_VCCA_OVUV_IMPACT; 0xE0, // INIT_VAUX_OVUV_IMPACT; }; static uint32 txData, rxData; static uint32_t sbc_start = 0; static uint32_t fs65_error_code; uint32_t reset_source; uint32_t fault_error_counter = 0; /*==================================================================================================*/ /* User Callback */ /*==================================================================================================*/ /****************************************************************************! * @par Description * When an error is detected by the functions FS65_Init() or FS65_GetStatus(), * this function is called.
