Hello,I am facing a connection issue with SPC5 Flash Programmer version 2.8.1 when using UART communication with SPC560B64.Setup:Target MCU: SPC560B64External crystal: 8 MHzInterface: UCUART::HybridCom/7/UARTSame hardware setup as previously used successfullySPC5 Flash Programmer v2.7.9 works correctly on an older PC, v2.8.1 (and newer) fails to connect.The software stays in “Connection phase starting” and continuously retries, the UART interface LED does not blink. No connection is established.Same SPC560B64 device, same UART interface and wiringAre there any required driver updates, configuration changes, or compatibility notes for newer versions?

In the datasheet it is given at 40MHz the max C_L is 8pF (from AN6027), but the C_L in the design schema has C1 and C2 8pF(UM3305), which gives 4pF, could you suggest me with the external crystal oscillator design. And the range is from 4MHz to 40MHz,  so if for a chosen crystal , should the minimum frequency satisfy this condition ?  

Dear ，       Would you teach me how to set SPC582B DSPI 40bit data frame? I use the SPC5Studio-6.0.0-Doyle, you can see my attached picture.The biggest setting of SPI frame is 32 bits.  but the data sheet says "programmable serial frame size of 4 to 64 bits, expandable by software control"Would you teach me how to set SPI frame 40bit?

I am using stellar studio 8.0.0.in Debug perspective, I can only find the Expression view, but cannot find the Live Expression view in "Window--show view". With Expression view, the monitored variable will be refreshed only when pause the debug session,if it has Live Expression view, I can watch the variable value without need to pause.So I want to know if stellar studio have made the Live Expression function or similar functions now?

I am trying to connect to the SPC574K-DISP board through PLS UDE Starter kit to program but am getting a "Can't determine the default communication device! Current selection is ambiguous!" Pop up error message.I followed the Part 7 - AutoDevKit™ detailed tutorial: Debug and release of firmware created with AutoDevKit™ tutorial step-by-step (though I'm using a different board, and I used the RLA IRQ Test Application). To get to this step.I am using a new SPC574K-DISP board for this, it has not been used/programmed since it came out of the box this week, so I can't verify that it's not a board issue. Though, when powered, the board runs it's Blink LED test application.Device Manager shows two instances of "SPC574K-DISP Discovery+" under "Other devices",

I have the SPC5Studio software installed. Installed everything I could find in the Help-> Install New Software. Found two help files in openocd-> docs section in the SPCStudio folder on the C drive. Only one applied, so as far as I know these are the latest drivers. UDE STK 5.2 and UDE STK 221 are both sitting on the desktop and do not do anything.Nothing I have tried has worked, any insight would be deeply appreciated.ThanksMike

Dears, How can I get SENT SW demo code described in TN1233? Thanks.

 I can use stellar studio to flash the new software when start a debug session, but I want a separate tool to just flash the new software just like Stm32CubeProgrammer.Does Stellar team have made such tools?

Hello,I’m experimenting with a simple RAM loader for SPC58 loaded through BAF over CAN.The same program runs perfectly when I debug it in RAM using UDESTK, and I’ve adjusted the linker so the code starts at 0x40070000. It initializes CAN, does a few GPIO tests, etc. — all good under the debugger.However, when I upload the same image to RAM via BAF, it starts but crashes as soon as it tries to initialize the clock, and if I skip that, it later crashes on peripheral initialization (CAN, GPIO, etc.).So my question:What are the main things I’m missing for a program executed directly from BAF in RAM?Is there something specific about system/clock or peripheral state that must be skipped or re-initialized when booting this way?Any hints or example references for a working SPC5 RAM loader via BAF would be very helpful.Thanks!— Janis

Hello, Is there any application like Power Consumption Calculator (PCC, which is embedded inside the STM32CubeIDE) for SPC5 microcontroller Family?I am using SPC58xCx and SPC58xBx lines and need the current consumption data for microcontroller core, peripherals, and I/Os.Best regards.

Dear ST Support Team,We are currently developing an IoT-based mining vehicle monitoring system, which generates a large volume of operational data that must be stored and accessed locally. Due to this high data size, we are evaluating the use of SD card or eMMC memory, with a stronger inclination toward eMMC as our final storage solution.For structured and reliable file handling, we are planning to use the FATFS file system for read/write operations.We would like to confirm whether the SPC58NH92E7 microcontroller officially supports integration with FATFS on SDMMC/eMMC interfaces. If available, kindly provide documentation, application notes, or official reference examples demonstrating FATFS usage with this MCU. Tool we are using to flash controller:SPC5 StudioAuto devkit Thank you for

Dear Team, @Max VIZZINI Sir, Help us to Solve this issue.We are currently working with the SPC582B60E1MH00Y MCU in our project development. In our application, the ESP32 reads the firmware file from the cloud and sends it to the MCU via UART.As part of our application, we need to implement a Bootloader using UART communication. However, we do not have prior experience with the Bootloader implementation on the SPC58 series MCU. The hardware design has already been completed, and the SPC58 UART is connected to the ESP32 through the LINFlex1 serial interface pins. Kindly confirm whether these UART pins can be used for the Bootloader application. We kindly request your support in developing the Bootloader application for our project. Additionally, if you could share any reference documents or sample projects (UART Bootloader code), it would greatly help us to progress further and improve our de

Hi Everyone, I´m trying to find the BSDL File for SPC56EC74B3C9EEX. Someone can share me the file.? Sincerely, Ruben Gonzalez

Are there any C++ Dual Core demos/examples/instructions for using the SPC58EG (or any SPC58 examples) for configuring, initializing and executing?

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

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.

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,

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.
