Customer may need more high performance via S32K3xx. How to optimization user's code? As following have some suggestions: 1. Most of user code allocate to P-Flash and enable I-Cache 2. Allocate system stack to D-TCM and enable D-Cache 3. Execute code frequently allocate to I-TCM. E.g., ISRs etc. 4. OS' task stack allocate to D-TCM 5. vector table allocate to D-TCM Please note: 1. Due to enable D-Cache, other masters(E.g., DMA, HSE, another APP cores) access theses area of cacheable will be impact. So, theses area need to allocate to non-cacheable area. 2. If another master(E.g., DMA, HSE and another APP cores) access the D-TCM need to over back door. E.g., core1/DMA/HSE access core0' DTCM needed to over backdoor. Information: S32K3' Coremark in RM, theses Coremark' value are from ARM. If used IAR/GHS etc and set compiler flag, then the Coremark value is very closely with RM. If used GCC, then the Coremark value will less than RM. BR Tomlin

******************************************************************************** The purpose of this demo application is to show you the usage of the FlexCAN module configured to use CAN FD using the S32 RTD API. - This demo application requires two boards, or single board connected with CAN tool. - CAN FD is enabled with bitrate 500/2000 kbps - It configures FlexCAN0 module and its transceiver (TJA1153). - MB0 is used to transmit CANFD std. ID - MB1 is configured to receive any std. ID - Callback function is used as well to handle TX and RX process in MBs. Received ID is echoed back. - setupCanXCVR function is called to Init TJA1153 connected to FlexCAN0 on the board. It expects transceiver in Vanilla state and set TPL to pass all std and ext ID and do not block any message coming from bus. Finally leaving configuration mode without writing to non-volatile memory nor locking the transceiver. * * ------------------------------------------------------------------------------ * Test HW: S32K3X8EVB-Q289 rev B2 * MCU: P32K358HVS 0P14E * Compiler: S32DS.ARM.3.5 * SDK release: S32K3_RTD_4.0.0_D2311 / S32K3_RTD_5_0_0_D2408 * Debugger: Lauterbach * Target: internal_FLASH * ********************************************************************************

Hi, If you try to compile the sample project within S32K14X_MCAL4_2_RTM_1_0_0, you should take care of the command if you use Linaro. After you set the environment of compiling and run the command under command window, you should enter "launch.bat MODE=USER TOOLCHAIN=linaro" NOT "launch.bat MODE=USER TOOLCHAIN=LINARO" The command is case sensitivity. Hope you can compile the project successfully. Cheers! Oliver

Example of usage of AIPS-lite, Protects the access to GPIO port. This example can be used with UART terminal, 115200 bps. The interface menu shows like this: AIPS example has started Please press 0 + enter to set red LED in GPIO port Please press 1 + enter to set red LED in GPIO port Please press 2: GPIO peripheral will only accept accesses from trusted master, M0 (Core) is set as untrusted when a write access, AIPS cannot longer be modified from core and a reset will occur in the next GPIO access Please press 3: GPIO access is write protected, any write access to GPIO will produce a hard fault
