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

This channel generates a waveform that will be captured by Channel 9 eMIOS Icu with DMA: Configures EMIOS 0 Channel 9 in ICU_MODE_TIMESTAMP using SAIC (Single Action Input Capture) mode. This channel captures the timestamps of the waveform generated by Channel 1. After a predefined number of captures, a DMA interrupt is triggered. ******************************************************************************************************* Any support, information, and technology (“Materials”) provided by NXP are provided AS IS, without any warranty express or implied, and NXP disclaims all direct and indirect liability and damages in connection with the Material to the maximum extent permitted by the applicable law.

This simple example demonstrates how to configure and handle UART interrupts using the LPUART module on both S32K312EVB-Q172 & S32K312MINI-EVB. It sets up a UART callback function and initiates reception in single-byte mode. After each byte is received, the buffer is updated using Lpuart_Uart_Ip_SetRxBuffer() , unless a newline character ( '\n' ) is detected, in which case a reception flag is set to signal the main loop. When the LPUART_UART_IP_EVENT_END_TRANSFER event occurs, reception is re-enabled using Lpuart_Uart_Ip_AsyncReceive() . Note: Only basic event handling is implemented; other UART events are acknowledged but not processed. The example uses LPUART instance 6, enabling serial communication via the USB port (J40 on EVB & J9 on MINI EVB). ------------------------------------------------------------------------------ * Test HW: S32K312EVB-Q172 & S32K312MINI-EVB * MCU: S32K312 * IDE: S32DS3.6.2 * RTD release: 6.0.0 * Debugger: PE Micro * Target: internal_FLASH ------------------------------------------------------------------------------ Running the example: 1. Open a Serial terminal on PC for the serial device with these settings: 115200 baud rate No parity One stop bit No flow control If using TeraTerm, ensure the transmit setting is configured to LF (Line Feed) to properly send newline characters when pressing Enter. 2.

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

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
