Solved

I am working with stm32h745ZIT3, in my application I need to receive some packets over ethernet in CM7 and these packets need to share to CM4, and processing is done in CM4. So, to test this data transfer I need to debug both cores simultaneously. Tried changing the debug properties as download option disabled for cm4 and add cm4 to cm7s list. and then tried to debug cm7 and then debug cm4, but cm4 shows as no ST detected. Also, port number changed for both. Is there anything I am missing? please guide me. Power: LDO 

Hi,The part# LD56020M180R Marking is 5618, is it correct? because i unable find the marking info from datasheet for this part, please see the photos of product below, thanks.  

If my data is more than one 32-bit word and I have to write it one 32-bit word at a time to the FIFO, is it possible that the USB controller could send just the first 32-bit word? Is there a way to stop that from happening?Thanks```USBx_DFIFO(1) = send.u32[0];// Is it possible for the USB controller to send just the first 32bit word if timing is right?USBx_DFIFO(1) = send.u32[1];```

Hello everyone, I am working on a wireless charger based on the STEVAL-WBC86TX, but we cannot find availability for the transmitter coil reference 760308111 among its components. We would like to know which other references would be compatible with the STWBC86 chip. Thank you for your attention.

Hello folks I am using the first bank for the firmware and the second bank to save a bunch of parameters. When the fw receives a command via uart, it updates the parameters erasing first and then writing groups of 8 bytes. When I try to erase the first page of the second bank (0x08040000): FLASH_EraseInitTypeDef eitd; eitd.TypeErase = FLASH_TYPEERASE_PAGES; eitd.Banks = FLASH_BANK_2; eitd.Page = 0; eitd.NbPages = 1; unsigned int page_error; HAL_FLASH_Unlock(); const HAL_StatusTypeDef status = HAL_FLASHEx_Erase(&eitd, &page_error); HAL_FLASH_Lock();the operation fails. I red this, so I added some breakpoint with __BKPT(0) instruction:   HAL_StatusTypeDef FLASH_WaitForLastOperation(uint32_t Timeout) { uint32_t error; uint32_t tickstart = HAL_GetTick(); /* Wait for the FLASH operation to complete by polling on BUSY flag to be reset. Even if the FLASH operation fails, the BUSY flag will be reset and an error fla

I found senduvdm callback in usbpd_vdm_user,c "USBPD_VDM_SendUVDM(uint8_t PortNum, USBPD_UVDMHeader_TypeDef *pUVDM_Header, uint8_t *pNbData, uint32_t *pVDO)"; and just found one interface,USBPD_StatusTypeDef USBPD_PE_UVDM_RequestMessage (uint8_t PortNum, USBPD_SOPType_TypeDef SOPType ), which can't set my data，and how to send an uvdm package after call a "send interface" ?

I saw a post from 2020, which said NO to raspberry pi, but that was before Apple's and Microsoft's latest machines started supporting ARMv7 architecture.Per the "STM32CubeIDE installation guide", section 1, states the following:Only 64-bit OS versions are supportedSTM32CubeIDE supports STM32 32-bit products based on the Arm® Cortex® processorFrom this, it appears that ST is telling us that Raspberry Pi is supported.  I think ST should immediately update the instruction guide to fix the 32/64 bit contradiction, and it would be ideal to make a clear statement that ARMv7 is only supported for Apple and Microsoft OSs.For another reason, I expect the instructions are wrong.  When I attempt to install the debian version on my Pi, it tells me what packages are missing.  Each one listed includes amd64 for architecture. The following packages have unmet dependencies: st-stlink-server:amd64 : Depends: libusb-1.0-0:amd64 but it is not installable st-stm32cubeide-1.17.0:amd64

Hello STM32 Folks, I couldn't find any information regarding the power consumption of ST33KTPM2IWLBZA9. The datasheet does not talk about this.  I am hoping that someone from ST could provide information regarding the power consumption. Thanks,

Hello, I faced *** problem because of *** website and can't download VL53 range sensor API.It may be that I'm *** as well. But every time this *** button does nothing: https://www.st.com/en/embedded-software/stsw-img005.html#st-get-software   So ST - how can I get your API,   Love you all!

Hi all,in my firmware I fall in a UsageFault but, since I have some tasks, I not able to understand which instruction caused the fault. Both PC and LR are pointing to the handler ..I attached the current screen.Thanks!

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) make -j6 allCompiling boot.sCompiling crt0.sCompiling vectors.sCompiling ivor.sAssembler messages:Fatal error: can't create build/obj/crt0.o: No such file or directoryAssembler messages:Fatal error: can't create build/obj/boot.o: No such file or directoryCompiling spc5_lld.cAssembler messages:Fatal error: can't create build/obj/vectors.o: No such file or directorymake: *** [components/spc560p

Hello,I am using an STM32WB55 and am trying to figure out how to get the current time including milliseconds using an RTC and display that time in 6 byte hex format. I would most likely call the GetTime() based of a millisecond timer if that is the most efficient way to do it.For example I would like the time to return like this (0x017FB1731312)Any help or example on this would really be appreciated.Thanks in advance!

here's a link to the GitHub issue containing the build output: https://github.com/giff25/MotorTest/issuesI double checked to make sure the HAL_TIM module was enabled, and followed the chain to the .h file itself and still haven't noticed any reason why the linker wouldn't see the TIM functionsIm using a nucleo board and the toolchain is as follows:built the project using CubeMX (including configuring the timer and pwm channels)Using VSCode with STM32 VS Code extensionany help would be appreciated

In my app, I need MCU to go to stop mode and then wake up by RTC timer. I follow this RTC wake up example and manage to make MCU go to stop mode for a few seconds and then wake up. Because in my app, we want MCU to wake up once in a few hours instead of a few seconds. The problem occurs when I try to increase the counter by 1000 times, the stop mode duration is still a few seconds. Can someone enlighten me what the issue is? Does the time counter have limit? It is an unsigned 32 bit integer, which can be very large. Or is it constrained by hardware?

Good morning community,I am using the STM32L496QGI6 for a certain application using the uart to send and receive messages, in this case it always gives me symbols even with the baudrate correctly configured, I have checked the clock configuration and it is correct for 80Mhz but when checking by means of a 70ms pulse on any pin it tends to have a phase shift of almost 10%, the SYS has been configured with the TIM3, what is the cause of this phase shift, how can I correct it? I have tested the same configuration with an STM32L476 and everything works correctly. 

Hello!I would like to report a bug. Using STM32CubeIDE 1.16.0 and the integrated STM32CubeMX 6.12.0 i encountered a bug regarding OCTOSPI and MDMA on STM32H723ZGT6 MCU. Inside HAL_SPI_Receive_DMA(handle, pdata); where the HAL_MDMA_Start_IT is called the destination and source pointers are/were swapped resulting so the DMA was writing 64 bytes into the DR register which was crashing my application. Swapping these 2 attributes fixed the issue and is now working as intended, below im adding the swapped code where the commented out line is the false one (incorrect one).Thanks for your time. I hpe some ST employee sees this and fixes it but if not at least someone will be aware of the issue when he finds it on google

Hi,I'll need one NUCLEO-H7A3ZI-Q in about a month. But next week the Trump administration takes over here in the USA and he promised to impose tariffs on Chinese products. I remember last time he was in office. Almost everything electronics got an extra fee (tariffs) when ordering (from digikey, mouser, etc). Are these nucleo boards made in China? Will they get more expensive next week if tariffs are imposed? I rather buy it today and save some money. I know for some people a few bucks is no big deal but money is tight for me right now.Thanks

Can anyone give a hint on where to look for proper documentation on CAN bus development? I see some primitive examples online, though there are a lot of moments that are not explained as they shouldFor example, CAN filtering and identificator masking are not reflected anywhere (as far as I look). Am I missing something?The CAN standard specification is there, of course. Should it be fullfilling in regard of development for STM?Sorry if I'm breaking local ethics of asking a questionThank you

Hi all,  I am using STM32U575ZIT nucleo board.  My goal is to write ODR register of GPIOD by using GPDMA transfer, using TIM2 to trigger the memory-to-peripheral transfer. In this "test" script, I use a 2-elements source array to force ODR all high and then all low. I want this operation to be continuous, hence the GPDMA is configured in circular mode. The configurations of TIM and GPDMA are attached as PNG, while the code lines in the main.c are the following: TIM2->DIER = TIM2->DIER|TIM_DIER_UDE; TIM2->DIER = TIM2->DIER|TIM_DIER_TDE; uint16_t prova[2] = {0xFFFF, 0x0000}; HAL_DMA_Start(&handle_GPDMA1_Channel0, (uint32_t)prova, (uint32_t)&(GPIOD->ODR), 4); HAL_TIM_OC_Start(&htim2,TIM_CHANNEL_1); What I see is that the timer signal is correct (1Hz freq), but the GPDMA seems not working (ODR never written)I think one of the main problem is that it's not clear to me yet the difference between trigger and request. Could you please help me? Thanks

HI We are thinking about a method for detecting people.   The prerequisite is that we need to detect people by penetrating a plastic case with a thickness of about 3mm (white). The existing PIR cannot penetrate the case, and radar sensors are expensive. So we are considering TOF...   The key is to detect people by penetrating the plastic case. I wonder if it is possible.    

This morning:Is it intended that the 'STM32CubeMX 6.13.0 code generation issue for STM32CubeIDE toolchain on macOS is fixed' post is listed twice?

Ive been trying to use the FDCAN systembootloader from a stm32H757XI, in the past i managed to use the CAN systembootloader from a stm32f405RE succcesfully. But im getting> nothing , i tried with 125 and 250Kbauds, CAN connceted to PH14 and PH13   Is FDCAN systembootloader compatible with STLINKV3+CubeProgrammer?

Is FDCAN Systembootloader described in AN5405supported by cubeProgrammer or the CLI tools?Because i only see the CAN (classic) option 

Hello,we use the STM32G474 with a single supply voltage of 3V3 at the VDD Pins.At the moment we investigate defective microcontrollers. The Microcontrollers are defective after several hours with the 3V3 VDD voltage supplied. The defective is an increase current consumption and not working i2c-interfaces.We connect two i2c-Interfaces with Pullups to 5V and at the moment we discuss if the 5V could be the rootcouse of the defective.For i2c1 we use PB9 (FT_f) and PB8 (FT_f) For i2c2 we use PA8 (FT_a) und PA9 (FT_fda) The FT I/O structure should be 5V Tolerant.I have found discussions of the maximum input voltages in your communityhttps://community.st.com/t5/stm32-mcus/what-is-the-maximum-input-voltage-that-can-be-applied-to-my/ta-p/49613 with these section:For the I2C Interface we use the microcontrollers  Alternate Function Modules and it think the alternate function module configures the I/Os as Open-Drain Output or Input.Am i right that it it is not allowed to

Hello everyone, does anyone know what type this is?I'm having a hard time finding it on the internet, I have a little problem and need to use this tool to make it work.
