HiI am using SPC584B70 and LIN transceiver(TJA1021T) for LIN communication and I have a question.TJA1021TI need to create a break signal first for LINcommunication but I don't know how to create this signal in the current library.The current structure is to pass serial data to the TJA1021T chip, and the chip converts it to a LIN signal and sends it to me.The library I am currently using is serial_lld.c and I have checked that Tx and Rx work fine using this library.

HiI try to program SPC564B74L7 target with using BAM function by serial port (SCI). I use an FTDI USB to RS232 adapter (USB-RS232-WE-1800-BT-0.0). Despite several attempts, I can't connect to the target from SPC5FlashProgrammer (version 2.8.1 Beta). In the Interface drop-down menu, I have selected my UCUART::FTDI/0/UART cable (which is the only suggestion). I have no activity on the serial bus when I click on Connect. Has anyone encountered the same problem as me and would they have a solution?

I am getting the errors below when trying to build the project.Due to reasons, we regenerate the project and now this project cannot be build ...I have tried the solution at Solution 1 and Solution 2. I have check that i have the full access to the workspace folders and the error illustrated below are copy and pasted from SPC5 6.0. (I prefer using 5.8.1 because it seems that opening up the project in 6.0 does import the correct low level driver setting correctly.)(We don't backup the component folders because it appears it need to be regenerated each time it is imported on a new PC) 

I've been using for a bit a SPC58 eval-board and i was wondering how to share global variables between the two cores. I searched around on the internet finding nothing useful. Is "volatile int" enough even for a rough and dirty data sharing or should I use something like SRAM and its shared memory location?

When replacing L917A how should I reboot it, what hardware or software do, I need please help.*This post has been translated from Persan to comply with the ST Community guidelines.

Is it because some jumpers on the SPC574K exploration kit board need to be connected, or is it for other reasons that the UDE STK software cannot read the chip through the emulator of the SPC574K exploration kit board? 

While debugging the board AEK-AUD-C1D9031 , the SPC5-UDESTK is not responding and it says this always even when the target power supply is turned ON and the Device is shown in Device manager. I think there will be some target configuration which I have to do but I am not aware of the Configurations. I have attached the message for reference. Kindly reply back as soon as possible.Message from component 'PpcJtagTargIntf' : Can't connect target !Message from component 'PpcJtagTargIntf' : No JTAG client found !Please check: - target power supply - JTAG cable connection - target configuration 

HiOn power up the SPC56EL54L5CBFS looks like it is in an internal RESET mode that does not  end. The RESET pin is always  pulled down by the CPU. Power up of 1.2v and 3.3v in 1.5msec. Can you help to to understand why the RESET pin is always  pulled down by the CPU? Thank you.

Hi,Can anyone help me?Thanks 

I’m engineer from EMS company. For one of our customer we are going to manufacturing PCBA (Vehicle Control Module) based on SPC58NH92C5 uC. Our customer is owner of design and our customer develop the final firmware for product. However for the manufacturing process we will need kind of the special firmware called “Test Firmware” optimized and dedicated to allow to perform Final Functional Tests of the PCBA. To optimize production process there is the plan to follow in that way: perform programming withfinal firmware > depanel and coating process > Full Functional Test (in here I need test firmware functionality).As you see I can’t reflash PCBA on Full Functional Test due to that PCBA already is flashed with final firmware. In that case my plan is do not touch Final Firmware but I would like to develop my own test firmware and I would like to upload That firmware do SRAM instead of Flash memory and boot uC from SRAM.I see that SRAM for t

I would like to know some information about OTP programming in production for the Stellar SR6G7. What are the pins required to set the high voltage? I couldn't find clear information about VDD_OTP in the reference manual. According to the reference, I can see an NVMTMI eFuse with VDDINT and VDD_HV_NVM_PRG. But i think these are no the pins. Where can I find OTP Programming information? Is there any production documentation available?

helloI have just started working with SPC5 studio and I want to use PEMicro for debugging, but no matter how much I searched, I couldn't find anything that could help me in this way. My main problem is that I can't I set the software to PEMicro to debug with this programmer, and I read all the questions in this field that were asked on the site, but it did not help me. If there is a tutorial in this field, I would be happy if you could help, thank you.

I Use SPC582B-DIS Board and i use flash driver provided in ST with DOC UM2636(Standard Software Driver for C55 Flash module embedded on SPC58 B, C, E, H, G and N lines microcontroller). My code booted from 0x00fc0000 in low address. and modify the large arddress(0x00100000) used by the flash dirver.Flash init and Setlock(for unlock) is are ok.but hard fault is happend when i excuted FlashErase Fnc. When i tryed the DataFlash(EERPOM), is ok.But when i try CodeFlash is fault.is there anyone who can help me? 

Hi,I am using SPC584B70E5 and I need to read the Brown Out reset condition in the controller by reading the reset register. I could not find any reference in the controller manuals to do the same.Is it possible to identify the Brown Out condition by reading the reset register RGM ?If not, is there any other way to detect Brown Out in SPC584B controller? Please help me out with this problem.ThanksRejitha

Hello SPC5 Community,I'm using SPC5 Flash Programmer since few years to transfer binaries on SPC564B74L7 as it easier for OEM than JTAG and because there is no access to JTAG on some device we created.On my last licence request (to:apgtools-license@st.com) I got an answer (from:antonio.martinez@st.com) telling that SPC5 Flash Programmer will be deleted from ST website because "it has not been updated for Windows 10 – 11".I'm surprised that there is no other available solution over UART/LINflex. And it works fine on Windows 10 and 11.Can provide more info and suggest other solutions how to load binaries in Flash memory?Best RegardsAurélien

Hi allThis is regarding ASM instruction "efsdiv", compiler is giving error for this instruction. is it valid or any equivalent ASM instruction we have please let me know. Compiler used is Windriver, MCU platform is SPC58E/G.

Hello dear Engineers.I am using SPC58EC Dev. board and want to use CAN BUS and UART in the same time. I can send Enter command from my keyboard to SPC58EC board via USB to TTL module (TX RX pins). But how can i do that, when i press enter it can send CAN BUS message and i can read from CAN1 port (DB9) with PCANView. Does anyone experience about this and can help me please ?PS. I can run Serial and CAN Test Application Samples seperately and I want to combine the twoThanks))

Hello,I'm trying out examples for the SR5E1-EVBE7000P development board. I use StellarLINK to implement the code on the flash and when I run it via RESUME the code runs. But if I execute Terminate and want to run the code without StellarLINK, e.g. by turning the development board power off and on or using the reset buttons, the code doesn't run. I think I forgot something fundamental. Can I ask someone for help? Compared to e.g. the SPC58EC-DISP, where I also tried StellarLINK, I uploaded the code and after turning the board power back on, the code runs automatically. What should I set up on the Stellar micr

The Application note AN3324 (Implementing power-on self tests for SPC56EL60 in locked step) says in Figure 2 (page 9) that one should "Enable All Peripherals" before initializing the FCCU. What does "enable" mean in this context? Does it mean setting the ME_RUN_PC and ME_PCTL registers so that the peripheral is active in RUN mode? Some peripherals have additional ways to turn them on or off, such as the ADC_MCR_PWDN bit that puts the ADC into normal mode. Should this also be done as a part of this step, or can this be done later (i.e. after the safety initialization)? Or am I missing the point completely, and this instruction refers to some other action that I should take?
