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.

************************************************************************************************ Detailed Description: WDOG tested in SystemInit() function (system_S32K116.c) after POR. For debugging purposes: - WDOG counter reference clock is pre-scaled to slow the test (CS_PRES = 1). - During CNT_LOW test, BLUE LED (PTE8) ON. - During CNT_HIGH test, RED LED (PTD16) ON. - Once both tests have passed, GREEN LED (PTD15) ON. If either of the test fails, WDOG will stay in its default configuration and rest the MCU. ---------------------------------------------------------------------------------------------------------------- Test HW: S32K116EVB-Q048 REV.B MCU: S32K116 0N96V Debugger: S32DSR1, OpenSDA Target: internal_FLASH ************************************************************************************************

******************************************************************************** Detailed Description: The S32K144 MCU is secure if SEC bits are set to non 0b10 value in Flash Secure Register (FSEC). And can be unsecure using either Mass Erase or Verify Backdoor Access Key command provided they are enabled, again indicated by bits KEYEN and MEEM in the FSEC register. The FSEC register is a read-only register and is loaded with the content of the flash security byte in the Flash Configuration Field located in program flash memory during the reset sequence. The configuration field holds the Backdoor comparison key as well and is configurable in startup_S32K144.S file. The attached example code shows use of Verify Backdoor Access Key flash command. The MCU is secured in the Flash configuration field and therefore once the application has been loaded the debugger does not have access to the MCU which must be run stand-alone. The state of the SEC bits is indicated by LEDs. The RED LED indicates the MCU is secure (SEC != 0b10) after reset. After a delay loop, the Verify Backdoor key command is executed which will unsecure the device and the LED will turn BLUE (SEC = 0b10). NOTE: The Verify Backdoor key command is executed from RAM to avoid simultaneous access to the PFlash block. -------------------------------------------------------------------------------------------- Test HW:      S32144EVB-Q100 MCU:           S32K144 0N47T Debugger:    S32DS1.3, OpenSDA Target:          internal_FLASH ******************************************************************************** 2.0     Sep-30-2017     Daniel ********************************************************************************

/******************************************************************************** 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 *******************************************************************************/

The S32K3 family of 32-bit AEC-Q100 qualified MCUs combines a scalable family of Arm® Cortex-M7-based microcontrollers built on long-lasting features with a comprehensive suite of production-grade tools. S32K3 MCUs are included in NXP’s Product Longevity Program, guaranteeing a minimum of 15 years of assured supply.

This example project will show user how to use and configure the basic functionalities of WKPU + GPT RTC API.  ------------------------------------------------------------------------------ * Test HW: S32K3X4EVB-T172 (SCH-53148 REV B2) or S32K344MINI-EVB * MCU: S32K344 * IDE: S32DS3.5 & S32DS3.6 * SDK release: RTD 6.0.0 * Debugger: PE Micro * Target: internal_FLASH  ------------------------------------------------------------------------------ This example routine configures the WKPU & RTC units for wake-up. The RTC is present in always ON domain, hence available in RUN mode as well as in STANDBY mode.   The chip contains one instance of RTC (Real Time Clock) timer and API (Autonomous Periodic Interrupt) timer, where both can perform 32-bit comparisons. Both RTC and API timers can generate interrupts as well as wake-up from low power modes. The following figure highlights the path for RTC API wake-up. Please refer to Chapter 69.3.2 API functional description from the S32K3XX reference manual (Rev. 12) for further information.   The routine waits for SW5 to be pressed, then: Turns off the green LED Switches CORE_CLK to Option C - Boot Standby mode (CORE_CLK @ 24 MHz). Initializes the ICU driver. Configures RTC_API channel (WKPU0) Initializes GPT module. Starts timer and sets RTC_API_TIME. Enters standby. After the period defined, RTC API generates an interruption and MCU wakes up. After wake-up, MCU resets and polls for SW5 to be pressed again. The RTC API value can be changed with RTC_API_TIME definition. This example is provided as is with no guarantees and no support.
