******************************************************************************************************** Detailed Description: LPUART1 echoes RX signal at 115200 bps When an 's' char is received, the MCU enters VLPS. A falling edge of the RX signal brings the MCU from VLPS via LPUART RXEDGIF interrupt. BUS_CLK can be monitored at CLKOUT PTD14. In VLPS, BUS_CLK is gated off. -------------------------------------------------------------------------------------------------------------------------- Test HW: S32K144EVB-Q100 MCU: S32K 0N57U Debugger: S32DS_ARM_2.2, OpenSDA Target: internal_FLASH ******************************************************************************************************** danielmartynek_0-1605283306283.png danielmartynek_2-1605283434147.png

NXP S32K1xx serial MCU is widely used in automotive body control and many general-purpose automotive applications, while to target some applications with special requirements such as requiring more peripherals instance than the portfolio can offer (e.g. 6x CAN-FD, 6x LIN or 4 I2C) like mid-end BCM or DCU, an on-board dual/multi MCU sync solution is proposed as an alternate solution to extend the S32K1xx MCU peripherals/memory resource and CPU process capability. The eRPC (Embedded Remote Procedure Call) is a Remote Procedure Call (RPC) system created by NXP(https://github.com/EmbeddedRPC/erpc/). An RPC is a mechanism used to invoke a software routine on a remote system using a sample local function call. eRPC software architecture Figure 1. eRPC software architecture In this project, we ported the eRPC protocol to S32K1xx platform, tested and figured out its performance. An out-of-box software package with detailed user guide (this document) is provided to simplify and accelerate users’ assessment of eRPC on S32K1xx. Two S32K144EVB boards are connected to demonstrate the usage of the eRPC protocol. One works as the client, another as the server. The client board starts an eRPC request and the server board responds to the request and executes the service. eRPC task workflow on S32K144-EVB.png Figure 2. eRPC task workflow on S32K144-EVB There are three types of MCU extensions are demonstrated in the project: MCU IO extension: Set LED; MCU peripheral extension: CAN and LIN message forwarding, LED luminance regulator; CPU process capability extension: Matrix multiply and addition math operation. Please find the attached sample projects and user guide for more details. Table of Contents in User Guide.png Figure 3. Table of Contents in User Guide •Note: Even though we did a lot of tests for the solution with the sample projects on S32K144-EVB, it’s still customer’s responsibility to ensure the total quality by themselves when it’s integrated in a real application project, all the sample codes and user guide documentation are just reference for customer. If you have any questions about this solution, please post here and we can have an open discussion. Best Regard, Enwei Hu(胡恩伟) GPIS System Apps Engineer.

/******************************************************************************** Detailed Description: Example shows possible implementation of multiple ADC conversions using SDK. Here 25 channels are sampled periodically. 2 ADC modules and 2 PDBs are used. ADC0 is configured to sample 16 channels, ADC1 9 channels. PDBs are set to back-to-back mode to perform chain conversion. Within ADC component you need to select ADC input to be measured for each item in configuration list. For ADC0 channels ADC ch12 is selected, as it is connected to trimmer on the EVB. DMA is used to read result into single buffer, and DMA callbacks are issued to indicate end of transfer for each ADC module. Within those callbacks PTE14 and PTE15 is toggled. PDB0 output pulse is generated on the PTE16 to indicate start of ADC measurement. This is done periodically at LPIT ch0 rate, which is set to 30us. The ADC0 ch0 result is used to dim LEDs. * ------------------------------------------------------------------------------ * Test HW: S32K144EVB-Q100 * MCU: FS32K144UAVLL 0N57U * Target: Debug_FLASH * EVB connection: * Compiler: S32DS.ARM.2018.R1 * SDK release: S32SDK_S32K1xx_RTM_3.0.0 * Debugger: Lauterbach Trace32 ******************************************************************************** Revision History: Ver Date Author Description of Changes 0.1 May-04-2019 Petr Stancik Initial version *******************************************************************************/

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

Hello, NXP does a big change on document structure. Generally, you can find pin assignment table, interrupt mapping and memory map table in RM. But now, these information change to Excel files and attached in RM. For example on S32K. You will find the words in RM, like 'For reset values per port, see IO Signal Description Input Multiplexing sheet(s) attached to the Reference Manual.' Then, please go to attachment tab of your PDF file viewer, like Adobe Acrobat Reader DC. These steps are also fit for MPC57xx , S32R family. Cheers! Oliver

Hi, ARM Cortex-M have a DWT (Data Watchpoint and Trace) unit implemented, and it has a nice feature in that unit which counts the execution cycles. The DWT is usually implemented on most Cortex-M3, M4 and M7 devices, including e.g. the NXP S32K14x. Attachment is the sample project on S32K142 to measure the running time of a function. Password of extraction is nxp. Enjoy the measuring! Cheers! Oliver BTW, Measure the running time of one function on PowerPC could also be gotten through the link.

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

******************************************************************************** * Detailed Description: * RAM self-test is performed after reset in startup_S32K144.s file. * The RAM self-test should be executed right after reset, so it does not destroy * data loaded to RAM by init functions. The code is inserted after * initialization of core registers. RAM initialization is commented out because * the same operation is done by the self-test. * The test flow is: * 1. Write pattern 0x55AA55AA to first word in RAM * 2. Read the data back * 3. Compare the data and increment error counter if not equal * 4. Write inverse pattern 0xAA55AA55 to first word in RAM * 5. Read the data back * 6. Compare the data and increment error counter if not equal * 7. Clear the first word in RAM to leave whole RAM erased to ‘0’ at the end of test * This procedure is repeated for whole RAM. * If the error counter is different from zero at the end, the program stays in * endless loop until watchdog reset. * * ------------------------------------------------------------------------------ * Test HW: S32K144EVB-Q100 * MCU: FS32K144UAVLL 0N57U * Fsys: Default * Debugger: Lauterbach Trace32 * Target: internal_FLASH * ********************************************************************************
