**************************************************************************************************** * Detailed Description: * * CM7_0 Safety Core (Lockstep): * * Runs as Domain 0 on the CM7_0+CM7_1 lockstep core pair of the S32K358. * Acts as the system master: performs full initialization of clocks, XRDC * domain assignment and memory region protection (Rm_Init), Port, Platform, * and releases CM7_2 from reset via Mcu_SetMode(McuModeSettingConf_1). * * XRDC memory layout configured by Rm_Init: * - 0x20480000 (SHARED_VARIABLE): Domain 0 RW, Domain 1 RW — Sema42 Ch 0 protected * - 0x20480010 (SHARED_FAULT_FLAG): Domain 0 RW, Domain 1 RW — Sema42 Ch 1 protected * - 0x20490000 (CM_0_OWNED_VARIABLE):Domain 0 RW, Domain 1 NO ACCESS — exclusive to CM7_0 * * Two Sema42 channels are used: * - Channel 0: guards the shared counter at 0x20480000 (competed with CM7_2) * - Channel 1: guards the fault flag at 0x20480010 (CM7_0 monitors CM7_2 violations) * * Main loop (continuous): * - Writes to the owned SRAM region (0x20490000) directly, without a semaphore — * XRDC guarantees exclusive Domain 0 access. Blinks BLUE LED on each write. * - Acquires Sema42 Ch 0, increments the shared counter at 0x20480000, * releases Ch 0. Competes with CM7_2 for the gate — mutual exclusion * is visible as either core stalls while the other holds the semaphore. * * XRDC_ISR_Handler (triggered by XRDC interrupt when CM7_2 violates 0x20490000): * - Spins on Sema42 Ch 1 until CM7_2's HardFault handler sets the shared * fault flag at 0x20480010, confirming CM7_2 has handled the violation. * - Acquires Ch 1 and clears the fault flag, signaling CM7_2 to resume * its main loop cycle. * - Together with CM7_2's HardFault handler, this implements a lightweight * cross-core fault notification and recovery handshake. * * CM7_2 Application Core * * Runs as Domain 1 on the independent CM7_2 core of the S32K358. * Only Sema42 is initialized here — XRDC and full RM initialization * are handled exclusively by CM7_0 (Domain 0, lockstep) before this core is released from reset. * * Two Sema42 channels are used: * - Channel 0: guards the shared counter at 0x20480000 (competed with CM7_0) * - Channel 1: guards the fault flag at 0x20480010 (CM7_2 signals CM7_0) * * Main loop (repeating cycle of 10 iterations, i = 0..8 + violation): * - Before each iteration, CM7_2 reads the shared fault flag via Ch 0 * and spins until CM7_0 clears it (fault recovery synchronization). * - Iterations 0..8 (9x): acquires Ch 0, increments the shared counter, * releases Ch 0, blinks GREEN LED to indicate successful access. * - Iteration 9: deliberately writes 0xDEAD to CM7_0's owned SRAM region * (0x20490000), which has no XRDC access for Domain 1. * This triggers a HardFault on CM7_2. After fault handling, variable i is reset * to 0 and the cycle repeats indefinitely. * * HardFault handler (triggered by XRDC violation on iteration 9): * - Lights RED LED immediately. * - Calls Rm_XrdcGetDomainIDErrorStatus() to read and decode the XRDC * error registers (domain, faulting address, access type, attribute). * Error registers are cleared automatically inside this API call. * - Acquires Sema42 Ch 1 and sets the shared fault flag at 0x20480010 * to notify CM7_0 that a violation was detected. ------------------------------------------------------------------------------------------------ * MCU: S32K358 * FXOSC 16MHz * RTD: S32K3_RTD_7_0_1_D2602_ASR_REL_4_9_REV_0000_20260206 * Debugger: PE Micro Multilink * Target: Internal_FLASH ****************************************************************************************************
