Automotive MCUs

Hello,Target: SPC584CWe integrated crypto rsassa-pss into our Primary Bootloader and Secondary Bootloader.Primary Bootloader is running on flash and to download Secondary Bootloader, while it uses almost 22s to verify signature.Secondary Bootloader is downloaded to RAM and runs on Ram to flash application. it uses 4s to verify signature.It is a huge difference since Secondary Bootloader is only 143K while application is 1157K. but it seems Primary Bootloader runs crypto slower than Secondary Bootloader on RAM.The crypto implementation is the same.Any idea why it is like this?Br,Kim

Hi,One question at the beginning: how to clear interrupt flag in SPC582B50 for "Flash controller Prog/Erase/Suspend IRQ" (vector 185)? I can't see any related interrupt flag in the manual, MCR.DONE also cannot be cleared manually.Once IRQ related to flash erase is issued, the IRQ_Handler is called over and over until I disable the interrupt at all (MCR.PECIE = 0).-----I found some incosistencies between Reference Manual RM0403 and actual behaviour of SPC582B50 flash registers.According to RM section 32.3.2.3 to 6 - all LOCKx registers should be set to all-1s after reset.I observe otherwise:The same secti

Good Morning!I need a datasheet for a component and I'm not getting it.The component is a driver that drives a main relay.Attached is the photo of it.Can they send?Thank you.

@Hi FOlks, @Erwan YVIN​ Intro and Question no.1 as follows:What is the HW programmer I can use to burn the flash on SPC56B line of uCs embedded in my custom board/design!?Question no.2 as follows:I have been since working with the SPC56B-Discovery board with a SPC560B54L5 onboard which is larger in size(144pins) and as I don't need that many pins so wanted to go with a SPC560B50L1 with 64 pins LQFP package but I'm not sure if they would be code to code compatible with the bigger 144pin (SPC560B54L5 ) uC!?

Hi,Is there a way to disable PLLs at all from the clock tree editor?If I change macro definition: SPC5_ME_DRUN_MC_BITS in clock_cfg.h, it is obviously restored when generating the application again ("Generate SPC5 Application" button in toolbox).Would you have any advice for this?Good day,Yannek

hi everyone.i have a problem of my CAN examplei have run example source on my SPC560BC50L1 chipon my SPC5Studio, there is no library for SPC560BC50L1 chip, so i use library for SPC560BC50L5and i set chip as SPC560B50L1 chip,when i set SPI communication, i was succesful to enable SPI by setting PIN editorbut, when i use can communication library, there is no PIN set on Library, it was empty.i run this example source code ( SPC560BCXX-OSLESS-CAN ) .it was done for running, but there is no signal on my Pin ( my CAN0 TX PIN is 14 )what should i do to run can example source on my chipsor what can i do to set my pinmap to use this library?

Greetings,I'm having an issue changing the state of the NOT_RDY bit in the MCR register of flexcan from 1 to 0. SInce this is a status bit, it relies on FRZ and HALT bit and reflects upon it. Inspite of changing the FRZ and HALT bits, the NOT_RDY doesn't change.Thank you for your help in advance

Hi,I have installed SPC5Studio in order to use my SPC584B-DIS dev board and I can't find a way to program / debug my cpu!! It seems that SPC5Flasher is integrated to spc5Studio but no way to find and use it. Idem for UDE. When I cliked on the debug icon nothing happens.Need help please!Regards

The code is as followed. When i delete TLB entry 1 configuration code, the program can run normally!! Why?:confounded_face: __asm void MMUTLB_init(void) {  /*configure TLB entry 1,start from 0x0000 8000,4MB*/ lis   r3, 0x1001      /* Select TLB entry 1, define R/W replacment control */ ori   r3, r3, 0x0000  /* clear the low 16bits of r3*/ mtMAS0 r3              /* Load MAS0 with 0x1001 0000 for TLB entry 1*/ lis   r3, 0xC000      /* Define description context and configuration control: */ ori   r3, r3, 0x0600  /* VALID=1, IPROT=1, TID=0, TS=0, TSIZE=0110 (4MB size) */ mtMAS1 r3              /

dear allI am use SPC5 studio with a cofig of SPC560P50L3,i want use etimer0/1 caputre and put this data to dma for signal cycle is 1.5us.when i open a new project and click “Low level drviers..�?,there i can find ICU mode maybe ​related to etimers ,but i can not find a palce to config etimer with dma.so,i anyone help me ? thanksZongsheng​

Hi,I finally managed to get SPC5Studio working, and have compiled the SPC56ELxx_RLA IRQ Test Application for DiscoveryPlus board.But when I press the Execute and Debug Button, I get an error messageMissing UDE target configuration!Target configuration does not exist - invalid launch configuration.Does anyone know how to fix this please?Thanks,Owen.

Message from component 'PpcJtagTargIntf' :Can't connect target !Message from component 'PpcJtagTargIntf' :Failed to connect probably because of wrong processor state !Please check:- JTAG cable and Target Power- Target's boot configuration- Target's PLL configuration- Censorship password configuration !Message from component 'PpcJtagTargIntf' :Processor is in UNKNOWN state !Message from component 'PpcJtagTargIntf' :Failed to halt processor !Message from component 'UDEDebugServer' :Unable to establish connection . To correct the situation, check configuration file entries and try again.

hello, i am new to this community and started working on the BLDC & PMSM motor controller for electric traction application. found STDES -EV001V1, i would like to know the details of connection and is it survive 50A current, is any addition i have to buy if i order STDES-EVT001V1

Hi i'm trying to use pwm on my board but every time on building i get the error "PWM driver activated but no Channels assigned". I also tried to copy and paste the code of the example on my project and configure the same pin on the pinmap editor but it gives me always the same error.

Our program can run when connected to the debugger, but it can't run automatically when unplugged and recharged. What's the problem?

Although SPC582B family has up to 7 FlexCAN modules, some units have only 3 (i.e. SPC582B60E1CD00X).Which 3 of 7 CAN modules are available in this processor?Since SPC5Studio shows 7 CANbuses for this processor, I don't know which I/O should I design for CANbuses.

Hi,Is there any hardwade design guideline for SPC58 like there is AN3024 application note for SPC56?There is a lot of power supply signals in SPC582B...E1 and very little grounds...VDD_LV_FLAVDD_LVVDD_HV_IO_MAINVDD_HV_ADR_SVDD_HV_ADV_SVDD_HV_OSCVDD_HV_IO_MAINVDD_HV_FLAVSS_HV_ADV_SVSS_HV_ADR_SVSS_HV_OSCWhich should be connected and which not?I found it strange that there is no ordinary ground signal (different than in SPC56). Which ground is THE ground? OSC?In SPC56 I had to put decoupling capacitors between adjacent VDD_LVs and VSS_LVs. But in SPC58 there is no VSS_LV and VDD_LV is far away from any ground pin...Thanks in advance,Yannek

Hi All,We are using SPC560PL3 development board in our project. I'm facing issue with board reset, My code works for some time and resets. I tried to check with exceptions added handlers in the irq.c file. I have attached the file for reference, Please check.When my board resets, I'm expecting some messages to print. But I'm not seeing any messages for reset issue. My UART works fine. Please let me know what I'm missing here. Do I need to set any option in the SPC5 studio? Or any code need to be modify to call these call back functions?Help me to solve this issue.Thanks,Basava.

Hi,Please suggest development board which has Flexray Interface. I have write Flexray Driver and can be used integarted with vechicle dignostics services.Thanks !Regards,Deepak

I am working with spc58nh92 microcontroller mounter on spc557xxMB and i am trying to measure the boot time of the microcontroller. i know i have to measure PORST signal from the microncontroller, but i dono whoch pin is associated with that microcontroller in order to measure the boot time.?
