Hello All, I am working on data storage on external flash memory, so for my application we are using SPC582Bxx MCU and W25QXX as external flash to store audio files into it. I have configured the below SPI pins to access the flash memory device, I have referred the sample DSPI code, with reference this sample code, i made the required changes to access the flash device. But unfortunately, I am unable to get data from the device. I am trying to read manufacture data of flash device first then writing operation. Configuration, as per the pin mapping above, we get the DSPI

I use spc58nh board.​I was using an RTOS Task On one core.​I want to use two core, and divide task into two cores.​​is this possible?for example : core2 - task 1, task 2 --> core 1 - task 1 , core 2 - task 2​

Hello ST Community, I am currently working with the SPC58NN84E7 controller and using the AUTOSAR SPC58NN MCAL version 4.0.3.I am in the process of configuring the PWM module for our project, which requires both the GTM (for clocking the counter) and the DTM (for dead time functionality).However, I have noticed that the AUTOSAR SPC58NN MCAL version 4.0.3 does not provide  DTM module to implement dead time functionality. Could anyone provide guidance on how to handle this limitation? Are there any workarounds or alternative solutions available for implementing dead time in this context? Thank you for your assistance!Best regardsVeer.

Hello everyone,I’m currently working on a project using the SPC584B70E1 chip and SPC5Studio as my development environment. However, I’ve run into an issue where the “Execute” and “Debug” buttons are grayed out, and I’m not sure how to proceed. After searching online, I found information about the SPC5-UDESTK, which seems to be a USB/JTAG debugger for SPC5 MCUs. I have a few questions about this:Is it absolutely necessary to purchase the SPC5-UDESTK to enable debugging, or is it possible to use a standard ST-Link for debugging with SPC5Studio?If I do need to purchase the SPC5-UDESTK, will I also need to buy any additional debugging software, or is it included?Are there any free options available for debugging? If using ST-Link is an option, could someone explain how I can set it up for debugging in SPC5Studio?I would really appreciate any advice or guidance on this matter. Thank you so much for your help!

Hello,  I currently have SPC560P chip which I am able to program using SPC5 Studio and Debug using SPC5-UDESTK. The compiler that I have currently selected is "FreeGCC with VLE Support" by going to the Application Configuration -> SPC560Pxx Platform Component RLA -> Build Settings.I see the other options in the dropdown of Compiler Variant such as Hightech and GreenHills. The issue that I am currently facing is that I am modifying only a part of the existing code and I need to use another compiler when merging with the old code. So I was wondering if I can change the compiler to "mwcceppc" from "FreeGCC with VLE Support"  in SPC5 Studio ? If Yes, how ? I have added the path to "mwcceppc" in the SPC5 Studio -> Windows -> Preferences -> C/C++ -> Build -> Environment. And also the same in Project Properties. But I believe the setti

Hi, I am developing SPC58EG in SPC5 Studio.I want to use I2C communication with a RTC device.However, I cannot find any example for I2C in the IDE.How do I get the reference to develop I2C?Thank you.

Hi ST Team, MCU is SPC584B70E1. CAN0 is used as ISR-Rx normally. I want to choose "CAN FIFO 0 Rx New message Interrupt" as Wake-up Source. In SPC5 Studio, I configurated on WKPU Configuration setting , I selected INT 0 as WakeUp Source and in the CAN setting FIFO is ENABLE vs. Without wkpu_lld_start() and STOP0 Mode, CAN works expectedly. With Filtered IDs ISR_Rx_Buffer_Callback() executes, with the specific (Wake-Up message) packet FIFO_Rx_Callback() executes. But together with wake-up configuration does not works.  Is it possible to use "CAN FIFO 0 Rx New message Interrupt" as Wake-up Source??If it is ,how? On SPC5 IDE, How to configurate WKPU settings?

Hi,I am using the SPC564B74 to measure the frequency of a square wave signal. The problem is that I have a some artifact measurements that cause problems on my application. A few times per minute, the measured frequency randomly drops to zero or an intermediate value and I don't understand the root cause. I made measurements and it is software related. I am using the eMIOS module in MCB mode. The signal is the output of a variable reluctance sensor measuring a motor RPM, ranging from  4 Hz to 8000 Hz.The SPC564 is clocked with a 40 MHz cristal. (FXOSC 40MHz → PLL 120MHz → Peripheral Set 3 Prescaler = 2 → Peripheral Set 3 = 60 MHz (ADC0, ADC1, eMIOS0, eMIOS1)eMIOS0 prescaler = 15 → eMIOS0 CLK = 4MHz For good precision in low and high frequencies, I am measuring 16 periods (32 edges) of the input signal. The measured signal is mapped to PA[1] and I am using eMIOS0 channel 1 as MC

Hi!When I trigger the built-in LVD self-test for the Power Management Unit by writing PMUCTRL.CTRL.B.SILHT = 1, the PMUCTRL_FAULT register immediately indicates a low voltage detector fault and the MCU goes into SAFE mode. If I trigger the HVD test by writing PMUCTRL.CTRL.B.SILHT = 2, then it indicates a high voltage detector fault. However, when sampling ADC channel 10 (VREG_1.2V) which is the voltage measured in these self-tests (if I understand correctly), then it says exactly 1.2 volts. So it appears the PMU is giving a false positive and reacting even while the voltage is OK. What could be the cause of this? At first I thought that the chip was just broken. But this strange behavior appears on three different chips that I have tried on, so it's not just one individual bad unit. Then I thought this might be a general error in the SPC56 chip. But the reference manual errata document does not mention this as a known design flaw.&nbsp

 SR5E1E7 IO_Definitions (excel file attached to TN1404) shows some information I need help with. There a sheet called "IO Muxing Table" where there are several possible functions for different pins on the SR5E1x series. One of the columns "Special mapping" has HSM UART and HSM DO functions listed for ports PA[6] and PA[7].I've looked in the datasheet or reference manual (RM0483) but not found the info I need. Where can I look to find an explanation of what that pin function does/how it works?Is it a special status for UART2 (listed as another alternate function for those ports) if used on those pins or an entirely different function?

I'm searching for a simple API call such as found on Arduino :theValue = analogRead(port);does such a thing exist?  Hoping for pal_lld_analogReadpad( PORT_x, pinNumber );I find in adc_lld.h there is an array of functions which I am unsure why they exist or how to use them.Is there an example for reading a port configured as ThanksPaul 

I want to clear the FCCU flags on my SPC56 chip. From the test application generated by SPC5Studio, I have the following code:static void spc_clear_fccu_rgm(void) {/* FCCU CF errors clearing.*//* Clear FCCU CF Status Register0 errors.*/FCCU.CFK.R = 0x618B7A50UL;FCCU.CFS[0].R = 0xFFFFFFFFUL;while (FCCU.CTRL.B.OPS != 3U) {}/* Clear FCCU NCF Status Register0 errors.*/FCCU.NCFK.R = 0xAB3498FEUL;FCCU.NCFS[0].R = 0xFFFFFFFFUL;while (FCCU.CTRL.B.OPS != 3U) {}/* RGM errors clearing.*/RGM.FES.R = 0xFFFFU;RGM.DES.R = 0xFFFFU;}  However, when I execute this on the chip, it gets stuck on the first while loop, since the OPS field is 0x2 (aborted). The reference manual (RM0032) states that:The ABORT response occurs in the following cases:– wrong access (missing or wrong key) to the FCCU_CFS register (clear operation OP11)–

I am developing a safety application on the SPC56EL60L3 platform. The reference manual RM0032 §43.1.3 outlines the steps for verifying the test results of the STCU (Self-test control unit). As I understand it, I first have to check the actual test status and then I should perform a number of extra checks using the STCU_LBS, STCU_LBE (etc) registers to see whether the test results are reliable. I have two questions regarding this. First, I am unable to find a clear instruction on how to actually do the first step, i.e. see the status of the test result. I assume I can do it by reading the FCCU status flags CF[20] and NCF[12], but that is not explicitly stated in the STCU chapter. Can anyone please confirm if I am correct in my assumption or if I should do it in another way? Secondly, in case of no reported errors, the manual tells me to "confirm that the signature registers of each of the LBIST results match their corresponding expected values"

I believe the following question has been posted in the wrong label by @Nagendrapeddina , hence I am posting here as it has not been answered:How to generate .s19 file using SPC5 studio? Is it possible to generate .S19 files in SPC5 Studio ? 

Hi All,I am using SPC50B60-L5 controller and spc5 studio (IDE) for building a project. And PEmicro multilink programmer for programming. I have built the project successfully. In build results I can see .hex, .elf, .bin out files but, I need .s19 file for flashing using PROGPPCNEXUS software. In project properties>c/c++ Build path I can't see any build settings for generating .s19 file. Can anyone please help me with this?Thanks

Dear Community, I am working on an SPI-based setup where I have one SPI master and four SPI slaves, each connected to the master via their respective Slave Select (SS) lines. The configuration for the SPI master and the chip select lines is set up using SPC5 Studio, with each slave having a separate SPI configuration. I am using the following function to start SPI communication with each slave:     void spi_lld_start(SPIDriver *spip, SPIConfig *config); and I'm using this like this spi_lld_start(&SPID2, &config1); spi_lld_start(&SPID2, &config2); spi_lld_start(&SPID2, &config3); spi_lld_start(&SPID2, &config4);     he challenge arises when I need to start all four SPI slaves simultaneously. Currently, I need to pass a different configuration to this function for each slave. However, when I start one slave,

I'm using the SPC5EC58 chip, and i want to switch some relays. This works so far. The problem is, during the reset mode even i'm setting it by Hardware like by a button or in the debugging mode, the pins which controlls the relays are set to high, can i somehow disable that ? because the board is used in a critical environment, where the relays shouldn't be triggered by something like the reset.

Hi, I using the GDB SEGGER J-link with JTAG debug, and stuck in  "Setting breakpoint @ address 0x24001362, Kind = 2, Type = THUMB, BPHandle = 0x0001Starting target CPU..." Please help, thanks~      

Hello, Stellarstudio how to set the code optimization?  During the process of compiling a.C file into an.O file, the code is optimized. Commonly used optimizations include time optimization, which aims to make the code execution time shorter and more efficient, and space optimization, which aims to reduce the space occupied by the generated code.

We are using SPC58xNx 32-bit Power Architecture microcontroller for automotive ASILD applications.We are using third party flashing tool to flash data section multiple time. We are able to flash hex file 12-15 times successfully. But random time it may failed to flash. Since We need to flash multiple ECU in production, we need to make sure each time flashing should happen successful. Tool is getting stuck and instead of programming request it triggering destructive reset. We need to know how to fix this problem.A ‘destructive’ reset source is associated with an event related to a critical, usually hardware, error or dysfunction. This reset aims to bring the system into a known safe state,Kindly find the attchment for more details.Is any SFR or Peripheral Register or Some debug method via we can identified Which was the reset source for destructive reset ? for ST Microcontroller?Please let us know how we can identif

Hi Team,   Could you please let if SPC58NN84E7 supports for asymmetric encryption. I could find the information regarding asymmetric encryption in the spc58 cybersecurity reference manual 

After installation of SPC5-Studio Green, I have copied my HighTec license file into C:\SPC5Studio-6.0\licenses, however SPC5 is showing the following screen.The path it wants for the license file is 'null'. What can I do to get the license file to be recognized correctly?If this license is not working correctly will the software be able to run properly? I have an ECU with code generated in Simulink using the SPC5-Studio compiler, does it need the license to be recognized for that compilation to work correctly?
