Automotive MCUs

Hi everyone,I’m working on a project using the SPC58NH92 MCU with SPC5 LLD (RLA) drivers.The setup runs FreeRTOS on Core2 and bare-metal code on Core0.Both cores share data through a dedicated RAM region, with synchronization handled by SEMA4 for access control and cache invalidate/flush operations to maintain data coherence.The application works perfectly when compiled without optimization (-O0). However, when I build with optimization level -O2, the system throws an unhandled exception during runtime.I’m using FreeGCC as the compiler (SPC5Studio environment).Has anyone faced a similar issue on SPC58 multicore systems?Are there any additional recommendations or known considerations regarding shared memory, cache management, or compiler optimization in this setup?Thanks in advance for any help or insights!

The chip we are using is SR5E1E7. Now we want to know how to perform SWD debugging. We have tried various tools, but none of them worked.

I couldn't find the silk-screen printing instruction document for this model SPC58EG80E5FEC0X. Please help check if these two silk-screen prints are of the same model. Thanks a lot.    

Hello,I am trying to run Projects\System\SIUL2\siul2LedBlink from StellarSDK_4.0.0 on a SR6G7EVBC4000P_RevA board. The project was successfully build. To flash the board in RAM, I am using the last version of Lauterbach. When running, it seems that it can't break on main.For testing purposes, I was running the sieve_ram_aarch32_arm_v8r_le.elf using the same Lauterbach script and the execution and breaking on main was done as expected. On a deeper investigation, I have found out that the .elf file form Lauterbach differs from the one build. Those differences can be seen below. Also, I have tried running an example from Lauterbach using the NVM, but I get the following error:  Do you have any suggestions to run Projects\System\SIUL2\siul2LedBlink on the board? Also, to flash an application on NVM and fix the flash programming error. Thanks in advance :grinning_face:

I need the BSDL file (Boundary Scan Description Language ) for SPC560B54L3C6E0X device, but I cannot find it on your web site. Can you send to me?NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hello,I have a problem regarding the slow initialization of eth1 on SR6G7 evbc6000 rev B board.The function xNetworkInterfaceInitialise() is failing multiple times, until it is succesfull.  From further investigation, I discovered that phy_check_id() is the cause of the failing. phy_check_id() is used inside dp83tg720_phydev_init(), which can be found here: ModExt/Drivers/Ethernet/DP83TG720/src/dp83tg720.c .Is there something that must be done before initializing the interface? Could it be a problem regarding the Ethernet cable?This behaviour can be seen using StellarSDK 4.0.0, using the ethPing project (Projects/Comms/Ethernet/ethPing). In order to use the eth1, in main() function I also registered the eth1 interface, like this: xNetworkRegisterIf(ETH0_INSTANCE, NO_HW_LOOPBACK);xNetworkRegisterIf(ETH1_INSTANCE, NO_HW_LOOPBACK); Thanks in advance! :) 

Hello, We have two discovery boards with SPC5 automotive MCU - SPC560B-DIS and SPC582B-DIS.We want to use them as basis for testing our hardware, and intend first run the tests with the discovery boards.Where can I find files required for testing regarding these boards - I am looking for SVF, STAPL and BSDL files, can I download them from the website (I failed to find them) or can you send me those files? Thank you in advance,Adam

There are several R52+ cores available in Stellar SR6 P7 line, e.g. SR6P7C8.I have question about the Symmetric Multi-Processing (SMP) support on these R52+ cores. Is SMP available inside R52+ cluster or among R52+ clusters?

I have flashed the application onto the HSM core of SR6G7, and I can see that the HSM core is not running up without a trigger from the Host core. After some analysis, I found that the HSM core requires a power mode change from DRUN mode to RUN mode via the ME_MCTL register. Therefore, I would like to know how we can enable the HSM core to run first by changing the ME_MCTL register value to RUN mode directly, without running the Host core of SR6G7. I want to ensure HSM core running first before host core running. Any help would be appreciated.

I would like to know that, what are the minimum DCF configuration required to activate the HSM core in Stellar SR6G7? Is there any Lauterbach cmm script available to flash the UTEST DCF configuration? 

To enable the HSM notification to application core, I understood that we need to enable HSM2HOST IE register. I would like to know which bit position of 32 bit, we need to enable to make interrupt activate ? There is no such informations in the safety document.   

Hi Team,For SPC58EE84E7QMSAR , Need Port/Pin Mux Functionality / allocation Details for Hardware Software interface specificationThanks,Chetan

Hello,I have SPC563M-Disp development board, i am trying to flash hex file in it with the help of AEK-MCU-SSPC5LNKU tool. each time i try to connect my board with the SPC5-Flash-programmer it does not respond. Need support

Hello, recently downloaded SPC5 Flasher V2.8.1, this is required to flash a custom board using serial (RS232) to load the CAN-Bootloader (SPC564B74 @40Mhz), subsequent loading of programs is done via CAN. The SPC5 Flasher appears to be not connecting to the USB/Serial Converter (no activity LEDs flashing). I have tried several USB/Serial devices (including genuine FTDI chip set) and both Win10 and Win11 PCs and a Win7 with serial port. I have confirmed all the system software is installed as required.  The flash tool does see the interfaces, but there is no USB activity when attempting connection on either interface selection.. I have considered older versions of the SPC5 Flasher, however these require licence files and from what I see in the posts, these versions are obsolete and licencing is no longer an active pathway.  Please advise if there is any specific drivers or config files required for the SPC5 Flasher for the USB>Serial devices.

When I installed the the latest StellarStudio v8.0.0 (https://www.st.com/en/development-tools/stellarstudio.html#get-software), seems like it has installed the SDKs for Stellar E family only. How can I get the SDKs for Stellar P family. The link above seems to claim, the StellarStudio provides comprehensive framework to design, build and deploy embedded applications for the whole Stellar SRx family (i.e. Stellar E, G and P) and not just Stellar E. Please canyou advice? 

Dear,I am trying to flash a SPC570S50E1 MCU through CAN. I have the SPC5FlashProgrammer software and a SH-C31A USB to CAN adapter. The MCU is flashed with "SPC570Sxx_RLA Bootloader Application for Discovery" example project from ST.The problem is that my USB to CAN adapter is not recognized in the SPC5FlashProgrammer software. I read that the software should be used with the SPC5-Connect interface but it is not longer for sale. Is there any other interface I can use with the SPC5FlashProgrammer software ? Or is there any other software to flash a SPC5xx MCU through CAN ?Thank you in advance,Best regardsClément  

Hi, for a new project is search an MCU with 4 CAN FD and the possibility to connect a 64GB EMMC memory to safe data on it.Due to the harsh environment, a solution with an SD card is not possible. Do you know if i can connect it to the Bolero?Do you know if there is a demo-board where i can build a test sample for this szenario?   

Hi,I get this message when I open SPC5Studio: but I have already followed the istructions for Free Hightech license coping the new license in the requested folder.Does it means to have less functionalities with wizard to configure the MCU? 

Hello All, I'm usin SR6P3 ARM mcu. I have to implement a simple SPI communication with StellarSDK. When send/receive starts the communication stucks in a while cycle where the code checks Tx queue busyness. while (queue->tx_busy == SPIQ_QUEUE_TX_BUSY) {                 ; }   Never comes out from this while. The clock is 1MHz. But if I set the clock lower like 50kHz, then the communication is good. This is the pin configuration: /*===========================================================================*/ /*                              SPIQ 0                                       */ /*===========================================================================*/ /* SPIQ0  CLK - PJ12 */ #define SPIQ0_CLK siul2_iopack(SIUL2_PORT_J, SIUL2_PAD_12) #define SPIQ0_CLK_

I'm trying to build the SPC5 Studio SPC582Bxx sample project using GHS.I'm getting a lot of syntax errors in the *.s files.Do I need to manually fix these errors?What's the simplest way to build GHS?

SPC564A datasheet promises compatability. Does that mean I can swap out SPC563M with SPC564A. Set target addresses in firmware, build and install, and all runs hunky dory?

Hello,Where can I find the BSDL file for this device? The SPC58EG84 alternative should work as well.Thank you!

Where can I find 'Getting Started' documentation for Stellar Studio - which is listed as SW dev tool for SR5E1E570C30F00X? For STM32 products, I was using STM32 Cube IDE which had Cube MX integrated (To generate driver code). I believe similar should be there for Stellar Studio. But I am not able to find any relevant documentation.

Hello,I am working with the UM2458 (STEVAL-CTM009V1 / CTM004V1) motor control evaluation board in SPC5Studio.In SPC5Studio project configuration, I see an L9907 Component RLA (driver + diagnostic). However, in the user manual and hardware schematic of UM2458, there is no L9907 IC present. Instead, the board uses the L6491D gate driver.Because of this mismatch, when I run Motor Control Live Monitor:I get Diag errors and register read failures from the L9907 tab.No gate drive outputs appear, even though PWM and VCC are correct.My questions:Does the UM2458 board actually use L9907 anywhere? (I think not, but SPC5Studio enables it by default.)How do I correctly configure SPC5Studio so that it matches the hardware (with L6491 gate driver)?Should I remove the L9907 RLA component from my project? If so, what’s the correct way to disable it?Is there any example project for UM2458 with L6491D that I should use instead of L9907?Thanks in advance for clarifying — I want to be sure I’m not debuggi

 Hello I'm trying to flash data on a large block, but I've seen that the current code stops with FlashErase or FlashProgram functions.So I tried flash control in two ways and none of them worked.1. divide separate section to flsh areas2. use the secondLargeBlockSelect parameterThis is the code that was trying the second method by separating separate sections on B0F11 and B0F12 Block.This way, it goes to FlashErase, but it seems that FlashProgram is experiencing an error.I feel like the SetLock part is not working correctly.  We are in the development stage just before mass production by contracting with an automobile company.I'd appreciate your help.Thank you.
