Hi all.I develop controller for PMSM motor and got a problem as below:Some time MCU jump to hardfault handler. In debug, I see that it cause from random point (different from time to time), some time it cause from very basic function (such as sinf(), cosf(), delay..), as belowdisassembly at <signal handler called>() at 0xffffffe9 as below:"ffffffe9:   Failed to execute MI command:          -data-disassemble -s 4294967273 -e 4294967413 -- 3          Error message from debugger back end:          Cannot access memory at address 0xffffffe8" I also think it may cause from hardware because inverter may generate lot of noise. But whenmeasure noise in power, clock of MCU, it is clean: as belowWhen hardfault about to occur, the debug connection on cube monitor corrupt many timeSo, where I can check for this issue?Thanks

Hello all,Working on communication between two STM32WB55 boards , one configured as client , and one as server.When trying to write a characteristic I get a bad parameter error, but when I use the write characteristic long command it works fine.Writing a small amount of bytes works on both commands.MTU discussed: 0xFB > size of write ( 0x5E). What can be the issue? Thanks!

Hello,Level : beginnerHardware : NUCLEO-F302R8 + X-NUCLEO-IHM08M1 + Qmot BLDC motorSoftware : Motor Control Benchwork 5.4.6, STM32CubeMX 5.6.0 and STM32CubeIDE 1.12.1I'm trying to follow this tutoriel : STM32StepByStep:Getting started with Motor Control - stm32mcu (stmicroelectronics.cn)First issue : when I try to use the ST Motor Profiler and click on the start profile button, I can't complete it because my board start smoking and the process stop because of overheating fault. What's the reason of that?Second issue : I open ST Motor Control Workbench to create a new project. I select Single motor as System,  Custom as Application Type, Power & Control as Selected Boards, NUCLEO-F302R8 as Control Board, X-NUCLEO-IHM08M1-3Sh as Power Board and Generic lov voltage <= 50V as Motor. I change the motor parameters, more precisely Electrical Parameters : 4 as pole pairs, 4000rpm, 5Apk, 36V, 0.35Ohm, 1mH and I leave the B-emf constant as default because I don't know what

i increases by 1.  The delay is 1.stm cubemonitor variables node I received the data as an Excel file.x is the time, and y is the value of i.The time interval of the data is 1 ms(=0.001s).Can you make the time interval shorter?If you can shorten the time interval, please tell me how to do it in detail. please.thank you. 

Hello everyone, I have board and I used STM32G071 MCU on this board. I want to activate RDP Level 1. There is my code:   void SysCodeProtection( void ){FLASH_OBProgramInitTypeDef pOBInit = {0}; HAL_FLASHEx_OBGetConfig( &pOBInit ); if ( pOBInit.RDPLevel != OB_RDP_LEVEL_1 ){HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); pOBInit.OptionType = OPTIONBYTE_RDP; pOBInit.RDPLevel = OB_RDP_LEVEL_1; HAL_FLASHEx_OBProgram( &pOBInit ); HAL_FLASH_OB_Launch(); HAL_FLASH_OB_Lock(); HAL_FLASH_Lock(); } } I'm programming my MCU on ST-LINK with ST-LINK Utility. But sometimes after I programmed my MCU It's locking or crushing. My power LED is not working on my board and I can't connect my board. I lost many boards after activate RDP If I disable RDP I didn't see any problems. Can anyone help me about it ?

Hi,Can anyone tell me why the STM32F103RBT6 getting heated, When ever I connected to the CPU through the USB port the ST-Link will not showing and the code also not Flashing and getting heated.Thanks,Kalyan

Dear SirGood dayPlease be informed that the attached JPG file is power card for CCTV camera, the supply , The camera is connected to an operating voltage 24-28 ACV.i need to know the part No. of  Z1.Please check and wait your adviceBest RegardsMostafa 

I2C was used in stm32, butIn the picture below, I am using the Write and Read functions, but the error message “busy” appears. Is there a way to resolve this?I'll post pictures and code together.

I'm using a custom board with a STM32L431RCT6 MCU and I need to activate the Ultra Low Power modes on it. I'm trying to use HAL_Delay before HAL_PWR_EnterSTANDBYMODE() and that's where the code breaks. Does anyone have any sugestion on how to fix the problem?I'm a beginner using CubeIDE and using microcontrollers in general.

Hi , I am using STM32L072CBT6 for my project. We have to use USB for configuration purpose. The controller VDD is connected to 1.8V power supply, but the VDD_USB is 3.3V. Is there any issue to connect 2 different powers ? 

Can I use STM32F401RCT6 to be I2C master and slave at the same time?1: For the Master, I use I2C1 -> pin PB6 and PB7, I will read data from the current sensor ICs.2: For Slave, I use I2C3 -> pin PA8 and PC9, I will send and receive data from another STM32.Does it work? Please give me advice.Thanks everyone, 

Hey, i am currently planning to work with the ISM330DLC and am wondering if its possible to change the full-scale selection of Accelerometer (CTRL1_XL (10h) - FS_XL [1:0]) during operation. Or is it mandatory to stop the ISM to change the control register values. I could not find any  information regarding that topic in the datasheet attached. 

I noticed that there is the ST25DV SDK for Java, but is there any package yet for iOS devices? I am currently using Flutter and I can use the Java SDK for Android, but there is no package for the iOS devices. If currently there is no package for iOS yet, is there any plans in the future to create a package in Swift or Objective C? Thank you before!

I use a STM32F469I-DISCO, developed with TouchGFX and CubeIDE.I've ever flashed with TouchGFX and all work fine.Now I need to send .hex file to customer, I'm going to use a standalone programmer like STM32CubeProgrammer to flash production with the same .hex file but actually I'm still failing.I'm using target.hex, that should be int+ext memory file, with CubeProgrammer but it's able only to updload internal flash (and it works) but doesn't upload external flash..I've tried to select IS42S32400F_STM32F469I-DK in UI CubeProgrammer "external loader", but doesn't work.I've tried with dos commandSTM32_Programmer_CLI.exe -c port=swd mode=UR -el ExternalLoader\IS42S32400F_STM32F469I-DK.stldr target.hexbut it return-------------------------------------------------------------------STM32CubeProgrammer v2.14.0-------------------------------------------------------------------Error: Wrong external loader file: target.hexAny help?Thanks

I encountered a problem with building project from STM32CubeMX v6.9.1 with generated Makefile and CMSIS_V2 enabled. Starting build by 'make' returns an error 1 for /main.o "Can not find specified file". On the other hand, when using CMSIS_V1 everything is building without errors.Is it something with CubeMX or CMSIS_V2 need some extra configuration, when using makefile from Cube? I am using GNU Make 3.81 for Windows and tried build it with two version of GNU Arm Compiler: v10.3-2021.10 and 9 20-q1-update.

Hi!I am trying to install the IDE on my macOS 10.13 (High Sierra), after completing the installation when trying to open it it gives the message: ' “STM32CubeIDE�? is damaged and can’t be opened. You should move it to the Trash. 'I tried to re-download it and re-install it several times, after deleting the previous copies, but after many attempts I get the same problem. I even tried installing the previous version but it said it was incompatible.Any suggestions? Thanks in advance!

With reference to STM32L496xx datasheet (DS11585 rev 17) page 152 table 49, can maximum values be provided for IVDD_VBAT with RTC enabled and clocked by LSE quartz, for VBAT=3.0V and at 25°C and 55°C? (The red marked cells)

Hello everyone. I was looking for the schematic of the STM32F207VGT6 but couldn't find it. Can anyone share this if they have it? Thanks. 

Hello everyone, I have a big problem with the hardware. I designed the hardware before dealing with the Cubemx. Starting from a circuit that worked, I mistakenly thought that giving the system RGB666 from RGB888 meant giving bits 0 to 6 R0...R6, G0..G6, B0..B6. I then connected the two bits of the display R0, R1, G0, G1, B0 B1 to ground, as shown in the figure. But I have the problem that everything is wrong.Is it possible to remap LTDC so I can see everything properly?Thanks for your help.  

Hi,I decided to upgrade my STM32CubeMX to the latest version 6.9.1.my project was generated first with STM32CubeMX 6.5.0 - so I had to copy the IOC manually.I checked multiple times that all configuration is the same like it was, and it is. when I'm calling the LWIP method udp_new() I'm getting NULL and than I can't send any UDP message.I did a debug and notice this is happening under "do_memp_malloc_pool" function in the memp.c file this is not happening in the old code generation. it there special configuration that I'm not aware of? thanks for the help!

 STM32MP157AAA  custom board with DRAM, SD- EMMC, USB and UART , Discrete power( no PMIC) . The board uses discrete oscillators for HSE and RTC, so they are set as Crystal OSC for both in CubeMX USB, UART are correctly configured (same as the default peripheral settings). DRAM is correctly setup based on the used DRAM chip. In .config the PMIC options is disabled and legacy power enabledThe CubemX settings were verified by the SOM manufacturer as being correct. This board has run a previous version of the ECO system without problems.TF-A uses SCMI but if the file #include "stm32mp15-scmi-u-boot.dtsi" is included, errors occur.To fix some other CubeMX generated dts file errors:a. Add a file stm32mp157a-<board>.dsti file in the main dts file. (which CubeMX did not add as an include). This fle is empty.b.. Add a binman entry to the stm32mp157a-<board>.dsti. Thee definition was found in stm32mp15-scmi-u-boot.dts and if not included u-boot fails with a message tha

Hi,I'm trying to get the infamous Synopsys OTG module to work. I'm not using the STM32Cube libraries, instead I'm rolling my own HAL based on the reference manual, which, as some have noted elsewhere in this forum, is pretty bad.Currently I'm stuck because the core is transmitting zero length packets in response to IN transfers on endpoint 0, no matter what I put in the FIFO or program in DIEPCTL0 and DIEPTSIZ0. Here's my code: static void _ep0_write(struct usb_module *module, size_t ep, const uint8_t *data, size_t length) { assert(module != NULL); assert(data != NULL || length == 0); assert((_OTG_DTXFSTS(module->base, ep) & _OTG_DTXFSTS_INEPTFSAV_MASK) * 4 >= length); _OTG_DIEPTSIZ0(module->base) = _OTG_DIEPTSIZ0_PKTCNT_VALUE(1) | _OTG_DIEPTSIZ0_XFRSIZ_VALUE(length); _OTG_DIEPCTL0(module->base) |= _OTG_DIEPCTL0_EPENA_MASK | _OTG_DIEPCTL0_CNAK_MASK; size_t word_count = (length + 3) / 4; for (size_t w = 0; w < word_count; w++) { // Yes we're prob
