Automotive MCUs

DearI noticed there are 64K core local RAM in the MCU SPC584C70E3. Does this area is used exclusively by the processor core? Can it be used as general SRAM by user code? If can, how to use it? Thanks!

I have just installed SPC5Studio 6.0 and I have opened GTM DPLL Test Application. I am getting the "Unresolved inclusion" error for#include "components.h"#include <build/mcs/mcs0.h>How do I resolve this? I don't seem to have any folders like the ones given for previous versions.

Hello ST CommunityI have got the SPC570S-DISP: Discovery Evaluation Board,I want to test it with a sample application from the library, but My computer has no driver, where to download it?I have no experience with SPC5 MCU, I just know about STM32 MCU.Thank you very much.

Hello,I can generate 4 PWMs ( 2 x Complementary Pair) with dead-time but I want to add phase-shift to a complementary pair which is one of them. How can I implement this?Best Regards

There is no file named DTM_UART.hex  in the installed folder of STSW-BLUENRG-DK.I reinstalled 2 times. please guide and there is no proper mention of the connections required in AEK-COM-BLEV1.pdf.

Unresolved inclusion: <string.h>where is the file exactly?

Hi,I've got the latest SPC5Studio 6 with all updates (gcc4.9.4) and testing on the SPC560D40L1 chip with the discovery board. So core is e200z0h VLE.I want to manipulate the flash in my app so I need to call some code from the RAM. I added the necessary sections in the application.ld, and the necessary attribute for my method :__attribute__ ((section (".codeinram"))) void method_in_ram()I'm calling this method from flash codevoid flash_method() { method_in_ram()}All this compile correctly (no warning, no error), but this crashes during debug with invalid opcode...I decompiled the hex, found that the flash_method content is not VLE code but PPC code !! e200z0h does not support PPC but only PPC VLE. Why is gcc creating PPC opcodes to call a method in RAM ? I tried to add longcall attribute but it does not help ...Any help appreciated!Thanks

Hi,In the sample application for SPC584BXXX flash test, the hex file is written on RAM and then executed. I need the hex file to get written on flash and then write some data on other specific sectors of flash. So I modified the linker script by changing the RAM sections by flash at some places but the program doesn't work as expected. Please help me to get an appropriate solution so that the hex gets written on flash and the FlashWrite Flashinit, FlashErase etc. will work as expected.Thanks in advance.

Hi Everyone,    As you know we are working on the Custom BLDC Driver Board with SPC platform in that we are facing the Some issue in the FOC integration.Current environment and setup:1. FOC Source code (SPC_MCTK_LIB) for SPC560p DISP Board2. FOC source code for X-Nucleo IHM001 Board.3. SPC560p Discovery Board4. X-Nucleo IHM001 Board with Bull running Motor.We are trying to replace the L9907 driver Board from the SPC_MCTK_01 kit with L6230 driver Board of X-Nucleo IHM001 Board.Queries1. Current FOC code Part of SPC_MCTK_01 has the L9907 driver code, We are trying to replace the l9907 driver code with L6230 driver code to suite our custom BLDC motor drive. Please guide us which and what part of the software has to be changed in order to make this integration correct.

Hi,The PEP flag (of FLASH_0.MCR) should be set when I try to write to protected block of flash.I observe, that this flag is cleared automatically at the moment of clearing EHV flag.Is it intended and should be written in RM? Or do I do something wrong?uint8_t DoFlashing (void ) { // clear potential error flags FLASH_0.MCR.R |= FLASH_0_MCR_ERROR_FLAGS; // start erasing/program FLASH_0.MCR.B.EHV = 1; // here PEP gets 1 because flash is LOCKED // active wait to be finished while (!FLASH_0.MCR.B.DONE) {} FLASH_0.MCR.B.EHV = 0; // here PEP returns to 0 FLASH_0.MCR.B.ERS = 0; FLASH_0.MCR.B.PGM = 0; if (FLASH_0.MCR.B.PEP) { // DOES NOT WORK !!! return FALSE; } return FLASH_0.MCR.B.PEG; }Best,Yannek

I have configured MDI and MDIO pins and wanted to verify mdio write cycle signal on DSO. So what other settings need to do apart from MDC and MDIO pin configuration. Do I need to initialize MDC clock? What are the settings need to do for MDC clock.Below is mdio_write function I am using.static void mdio_write(volatile struct ETHERNET_tag *reg,uint8_t phy_addr, uint8_t reg_addr,uint16_t data){ reg->MAC_MDIO_DATA.B.RA = reg_addr; reg->MAC_MDIO_DATA.B.GD = data; reg->MAC_MDIO_ADDRESS.B.PA = phy_addr; reg->MAC_MDIO_ADDRESS.B.RDA = reg_addr; reg->MAC_MDIO_ADDRESS.B.GOC = GMII_WRITE_OP; reg->MAC_MDIO_ADDRESS.B.GB = 1; dwmac_qos_mdio_busy_wait(reg);}

HiIs STA1385 Telemaco3P supported by Arm KEIL MDK?else what are the alternatives for programming and debugging?Unfortunately there is little or no info. on this processor on the ST websitehttps://www.st.com/en/automotive-infotainment-and-telematics/sta1385.htmland none at Keil websitehttps://www2.keil.com/stmicroelectronics-stm32Thanks

Not sure this is the right section...but I would like to know if it is possible to use the L9177A with an hall effect sensor, in that case, I guess the signal is to be routed to the VRIN+ input, what about the VRIN- input?Must be connected to GND or to a some threshold voltage? whats the level of the signal the L9177A will recognize with hall sensor signal?Thanks a lot.

Hi guys,i have the following problem. I configure the interrupts as follow.INTC.BCR.R = 0; INTC.IACKR[0].R = (uint32_t)&VectorTable[0]; INTC.CPR[0].B.PRI = 0;   // enable interrupts __asm__ volatile ("wrteei 1" : : : "memory");After that, i configure one Etimer Channel with timer compare interrupt. The interrupt flag will set in etimer module, but the ISR will never be called.If i change my configuration to the following, the interrupts will come:INTC.BCR.R = 0; INTC.IACKR[0].R = (uint32_t)&VectorTable[0];   (void)INTC.IACKR[0].R; // read back   INTC.CPR[0].B.PRI = 0; // enable interrupts __asm__ volatile ("wrteei 1" : : : "memory");I would be happy if someone could explain what I'm doing wrong, because I can't find anything about it in the reference manual.best regardsdavid

The sleep mode option in SPC560P-DISP Discovery (SPC560 P Line) is removed as per reference document. I have attached the revision history screenshot of reference document.My question isis SPC560P-DISP Discovery board have sleep mode option or not?please see the image for reference

Hi Technical Team,I have SPC560P-DISP Discovery board which is based on the 32-bit microcontrollers Power Architecture® Core SPC560P50L5. For programming this board, i am referring "RM0022 Reference manual"( revision history of document : Revision - 8 and Date :10-Jul-2015). SPC560P-DISP Discovery board has 32 external interrupt only (Table : 99 (EIRQ[0:31]) in reference document ). But i need to configure 80 input resources as external interrupt. My question are1. How can i directly configure 80 input resources as external interrupt?2. If it is not possible for 80 external interrupts, what is the alternate solution for this?Please provide your input to proceed my development work.

Good day,I might be missing something, but an issue cropped up when I moved to SPC5 Studio 6.0.0 Asimov when attempting to compile any project that includes the MCTK Web Library. The message that I get while building is:./components/spc56xx_web_motor_control_component/lib/System_Drive_Params/src/Spc5xxx_MC_it.c:48:21: fatal error: pal_lld.h: No such file or directoryAny ideas as to why this might be happening? Thanks in advance.

Hello!​I have a SPC58EC-DISP; I set the PWM frequency 20KHz and duty cycle 1%,then it's not output,when set 8%,it's output 2us time;I found that the minimum PWM output time seems to be 2us.now I want PWM frequency 20KHz(50us) and 1%(0.5us) ouput,what should I do?

Hi All,I need to record time stamps in the code, how i can do it? is there any example code is available?Thanks,Basava.
