We are trying to erase a flash sector during reprogramming by using the flasherase() function provided by st. The flash erase function takes around 220ms causing the hardware watchdog reset. Any inputs?

SPC5Studio cannot use the malloc() and free() functions in the stdlib.h standard library.​For Example:char * str = (char *) malloc(1024); free(str);​​I've added the GCC standard header path to SPC5Studio, and other library functions are used normally, and I can't compile through when using the malloc function, reporting the following error:​c:/spc5studio/eclipse/plugins/com.st.tools.spc5.tools.gnu.gcc.ppcvle.win32_4.9.4.20190604105544/toolchain/bin/../lib/gcc/powerpc-eabivle/4.9.4/../../../../powerpc-eabivle/lib\libc.a(lib_a-sbrkr.o): In function `_sbrk_r': sbrkr.c:(.text._sbrk_r+0x1a): undefined reference to `sbrk' collect2.exe: error: ld returned 1 exit status make: *** [build/out.elf] Error 1​​How do I solve the problem that malloc and free are not available, or how do I dynamically allocate memory in SPC5Studio?​Thank you.​

Discovery broad SPC528B-DISSPC5Studio 6UDE STK 5.00.05OS: WIN10 64BIT​1. i imort this sample project: SPC582Bxx RLA CAN Test Application for Discovery .2. follow sample code cand2 and cand7 enable sub0 mcan1 and sub1 mcan1,but i can't work( no loopback mode).3. if i enable additional "mcan 0 sub0", cand2 and cand7 can work.i have no idea what happen. ​

Hello, we bought 3x SPC 582B-DIS Eval Boards. I tested the first one with one of the examples provided in the SPC5 Studio successfully ~2 months ago. Last week I tried to put it into operation again but in Windows it's not recognized ("unknown usb device (port reset failed)"). I thought that this might have been due to ESD issues or mechanical stress during storage, so I tried the second Eval Board which was working perfectly at the beginning. This time I was more careful (Operation and storage only in air-conditioned ESD lab).Nevertheless, the Board worked less and less over time while testing several examples (always lost USB connection during operation - needed to reconnect USB). Now the board is in the same state (not being recognized by Windows), no matter how often I plug it in and out.Especially for the second board I took care that no mechanical or electrical stress (not even electrical measurements) were applied.In the device manager, it's displayed as "unknown usb device (dev

This document: https://www.st.com/resource/en/user_manual/dm00082034-standard-software-driver-for-c90lc-flash-stmicroelectronics.pdfdescribes a flash library intended to be used with JTAG on the SPC5 family, which we would like to use for our CI. However, we have not found the library itself anywhere. Is there any direct link available for downloading the library? Also, is the source code available? ThanksLuis

In the SPC570S50E1 datasheet in 1.3 Features overview (p.9) it says:2 LIN and UART communication interface (LINFlexD) modules– LINFlexD_0 (master/slave)– LINFlexD_1 (master)Does this mean that if I need a slave, I can only use LINFlexD_0?

Hello,I would like to get program in C for FOC field oriented control.On site page 15 it says that you have to Get Motor Control SW package(ask ST regional office). How to contact ST regional office? page https://my.st.com/content/ccc/resource/corporate/company/divisional_presentation/group0/15/c9/6a/b0/10/2a/40/ce/7_Motor_Control_Tool_Kit_SPC5Studio_Overview_Zhang_Livia/files/7_Motor_Control_Tool_Kit_SPC5Studio_Overview_Zhang_Livia.pdf/jcr:content/translations/en.7_Motor_Control_Tool_Kit_SPC5Studio_Overview_Zhang_Livia.pdfBest regards,

Hi want to know if on ​SPC584B-DIS is possible to connect an encoder using endat 2.2 interface and if yes there is a library to read the data send by the encoder?Thanks in advanceLudovico​

I have been looking for it everywhere in st.com and couldn’t find the reference manual for the board. Does anyone know where can I get it?

I have a quite big project for SPC582B in SPC5Studio.When I am building entire project - a lot of temporary files (really A LOT!) content is printed on the console. It takes literally over a 2 minutes to wait for the compilation to finish. UDE STK finds new out.elf about 40s after start of building, this is also the time of building counted by SPC5Studio (as I have about 40 files - it is reasonable):12:19:40 Build Finished (took 41s.5ms)But I need to wait over 2 minutes for the SPC5Studio finishes printing the output.Build Log file has over 20MB and it seems all to be printed at console.How to get rid of all these temporary files from the output console? I'd like to have only errors and warnings there, but because of vast useless texts I can't even see error messages.Switching "Use verbose compile" setting does not change anything.Best Regards,Yannek

Hi All,Please help me to solve this below error.Unable to find component plugin named 'com.st.spc5.components.ee.spc560pxx'Thanks,Basava

Hi All,I'm looking for Flash write, Read and erase APIs for SPC560 series controller. I'm not finding any example code with source code. I have checked the example bootloader code and it's not self explanatory. Please help me to find one. Thanks,Basava.

Hi Team,Please help to resolve the issueFlashing the SPC584B- DISP board failed and end up in the following errors,  Error messages:  PpcJtagTargIntf: Connection to target lost !  PpcJtagTargIntf: Failed to reset target system !  PpcJtagTargIntf: No JTAG client found ! Please check: - target power supply - JTAG cable connection - target configuration This issue has started just after connecting with external LIN device(NeoVI Blue). All indicator LEDs in the board are still glowing. The device is still visible in Device Manager under Ports on connecting with the computer. There is no fluctuation in the current observed. The power is given through regulated power supply keeping maximum current 200mA.RegardsSudeendra S

Hi,I'm designing an automotive scan tool. For now, I'm studying about ISO 9141 and LIN Bus compatibility. I have a legacy hardware that uses L9637 to perform ISO 9141, but I want to add LIN capabilities in a new hardware.So, I would like to know if the IC L9637 can support both protocols ISO 9141 and LIN bus ? If not, is there a IC that can do this ?Regards,Daniel.

I am interfacing AEK-COM-BLEV1 with SPC58ECXX .I imported the ble demo code from autodevkit but while compiling it is giving some errors like:In file included from main.c:19:0:./components/AEK_COM_BLEV1.h:23:31: fatal error: AEK_COM_BLEV1_cfg.h: No such file or directory#include <AEK_COM_BLEV1_cfg.h>^compilation terminated.make: *** [build/obj/main.o] Error 1I think some files are missing.I am not able to find this file AEK_COM_BLEV1_cfg.h:Please guide how to solve this.If anyone is having compiled demo code for AEK-COM-BLEV1 it will be helpful

Hi,I'm doing a HW rework design about a board that use the microcontroller MPC5606B of NXP. I want update the design using a ST microcontroller. I have seen that this device is similar to the SPC560B60L7, but I would like to know if the 2 IC are pin-to-pin compatible. In particular, is it possible to replace one component with the other one without modify the electrical connections already present on the board?The complete part number identified are: SPC5606BF1VLU6 (of NXP) and SPC560B64L7C6E0X (of ST).Thank you,Regards.

Hello there,I want to enable/disable JTAG in SPC56EL60 microcontroller, however i did not found such information in reference manual. Could you provide clarify how can JTAG can be enabled/disabled from Sw? Thanks

I am trying to install autodevkit plugin using install new software option from help but some features are not getting installed.I am getting the following error:Missing requirement: Autodevkit feature Group 1.1.1.20200327200248 (com.st.tools.autodevkit.feature.group.feature.group 1.1.1.20200327200248) requires 'com.st.spc5.components.spc5rla.usbtypec.full.feature.feature.group 1.3.2' but it could not be foundI think this error is linked to the missing feature/improper installation of autodevkit.Please guide .

..

I know how to burn the firmware but it is not required i think. I downloaded the sw mentioned in this link: https://www.st.com/resource/en/data_brief/stsw-aekble.pdfbut it is not gettting imported or compiled in spc5 studio so i can open it later in UDE for flashing the ble board later.Also where is this connector on ble board  J2541409? I am not able to find proper user guides or manual.
