Solved

Hello,I am developing an application on STM32H7 MCU which uses SBSFU bootloader for secure firmware updates. I am trying to combine the SFB update package with some additional data in a single binary file that is sent for the firmware. To make this work, I need to determine where the SFB update package ends and the additional data starts in the binary. To this end, I check the firmware header of the update package. I noticed that the actual size of the SFB update package is 1024 bytes larger than the update size reported in the header. I expected SFB size to be larger than the firmware itself since the SFB package contains the header in addition to the update, but the header size is only 320 bytes.So I am wondering what does the SFB update package contain and can I be sure that its size is awlays the firmware size in the header + 1024 bytes?Thanks!

i want to know the weight of the below component M24512-DRMN3TP/K.

Hello,I plan to use STM32H745 controller with touchGFX for UI. Additionally need WIFI capability. What options are available if WIFI is to be used with STM32H745? I dont want to invest time in developing a communication protocol to communicate with a WIFI module.Are there any ready made options available from both Hardware and Firmware side? Please suggest any development boards which can be used to accelerate development.Thanks Anuj 

I am working on a ThreadX project on my STM32H747I-Disco with M7 and M4 cores. I want to allocate memory dynamically in the initialization phase that can be accessed from both cores. For this, I am planning to use the "tx_byte_pool_create" and "tx_byte_allocate" APIs. The former requires the starting address of the memory pool. The example in the ThreadX user guide shows that it can be any memory location, such as 0x30000000. As I want to access the pool from both cores, I assume the memory location has to be in one of these locations (AXISRAM, SRAM1, SRAM2, SRAM3, SRAM4, BKSRAM). Now, I can get the address of these sections in the reference manual, but how do I know which one to select? Some sections will be used for the stack, which can grow. How can I ensure that the section I am selecting for the pool will always be available and not overwritten by the system?In summary, I want to understand how to select the start address for the memory pool in RAM, which will remain valid indefin

Hi all,When I config the textArea initial value, the character order I config is different with the display order.After some test, I find this is because of the character "-".I already meet this multi-times, is this a bug?Thanks

I don't care if the title of this post breaks some sort of forum usage rule, I just need to make it absolutely plain that I am sick and tired of every last company on Earth insisting I have an account with them and use it whenever I so much as breathe, drink a glass of water or, Chtuluh forbid ! update a HAL library for a microcontroller. I believe there are more than enough bugs in CubeIDE, let alone actual necessary features that are missing, to keep your developers occupied forever. You did not need to waste everyone's time forcing people to login to ST. This feature brings nothing, helps no one but yourselves, and was asked by absolutely nobody, ever. So please, may I suggest you rethink this stupid, bordering on evil new addition to CubeIDE, and remove it with the next version ? FYI, some of us work in companies where our computers are not, must not and cannot be, connected to the internet. It's already tough enough installing some of your HAL libraries (the patches) while being o

Hello ST Support Team,I am currently facing an issue with the BLE functionality on my custom board utilizing the STM32WB55CE MCU. While the code works flawlessly on the STM32WB Nucleo EVK, the BLE feature doesn't seem to function as expected on my custom board.Upon further investigation, I observed a disparity in the wireless firmware version and build values between the two boards. When running the code on the EVK, I received wireless firmware version 1.13.2 with a build value of 2. However, on my custom board, both values indicate 0. Meanwhile, both boards display the same FUS version value, which is 1.2.0.I have also tried to re-flashing of BLE firmware but receive the error in flashing.I used following link for reference and follow all steps. Also used "stm32wb5x_BLE_Stack_full_extended_fw.bin" file and address "0x08051000".https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WB_BLE_Hardware_Setup I tried to flash the BLE stack firmware multiple times but not worked in my

On STM32F205VGTX, when I put cpu in sleep by using this command: HAL_PWR_EnterSLEEPMode(PWR_LOWPOWERREGULATOR_ON, PWR_SLEEPENTRY_WFI); CAN peripheral stops working. It does not acknowlege bus messages anymore and there is no CAN interrupts to wake up the cpu.I had a look at the datasheet, I was not able to find whether CAN is supposed to or not supposed to work in cpu sleep mode.My question is if this is how it is supposed to be, or I need to do some more to keep CAN alive in this mode. Thanks

We're currently having issues with our inverter.To further analyze the issue, I'd like to test the proper function of the motor phase current measurement.How should I go about doing that? Since the motor currents are measured in injected mode syncronized to the timer, I cannot just insert a static current into the shunts and look at some registers.Is there a way to enable a "test mode"? Could I use the high speed plot for that?I already tried running the motor and graph the input of the motor current ADCs with an oscilloscope to compare it with some of the plotted graphs, but I could not find any that matched.

Hello,We are using the VL6180X in a IVD product and need laser test certificate documents to show the range sensor is class 1 and safe for the user. Can you send me a test reports for this part? I see a CDRH report posted for VL53L1, but couldn't find it for the VL6180.Thanks,Andrew

Dear STM32 communityI am trying to setup the ST7735 Display (ST7735) with SPI and DMA for a faster refresh rate. Without DMA everything works fine. When i setting up DMA nothing is displayed on the Display.My DMA and SPI Settings are:I want to fill the Screen with black color, for this i use the function fillScreen() from GFX_FUNCTIONS.c. To Transmit the data via DMA i have replaced the old functions in ST7735.c with the DMA Transmit function in ST7735_FillRectangle(), ST7735_WriteCommand() and ST7735_WriteData().For detail view i have attached the main.c file and the library files from the Display (ST7735.c and GFX_FUNCTIONS.c). I am using a Nucleo-G474RE Boeard with STM32 Version 1.15.1.I really someone of you guys could help me.Thanks a lot for your time!Best regards,Raphael

The Motor Pilot 6.0.0 application is not starting. I have testet it on Windows 10 on a real machine and on a Windows 10 virtual machine. When I start the application the course briefly shows that the machine is working but then nothing happens. No error messages.Has anyone experienced similar issues?

In the STM32F469, can the bus arbitration priority (amongst the different bus masters) be changed? From my reading of the Application Notes and the Reference Manuals this doesn't seem to be the case. But I'd like to get a confirmation just the same.  I wanted to give DMA2 a higher priority over the core, but I suppose that's not how it works by default (or at any point, if the arbitration prioriy assignments are fixed)

Hi everybody, how can the CPU1 of module STM32WB5MMG be waken up by the RF subsystem?The idea in mind is to use the module as a BLE Server, have the CPU2 perform advertising while the CPU1 is in STOP2 mode. According to the reference manual RM0434, this could be done?  And in the Datasheet of STM32WB55xx, the RF is listed as a possible wake up source as well.Waking up with the the RTC, an EXTI event and EXTI interrupt worked, but the CPU2 stops its advertising shortly after the CPU1 goes to STOP2 mode, even though the low power mode for the CPU2 is disabled. I thought that the CPU2 would continue the adversiting and either the EXTI listed as "CPU2 SEV interrupt..." or "PWR switching on the fly, ..." could wake up the CPU1 if a connection is requested from the client. Obviosly I am missing somehting, does anybody has an idea of what am I getting wrong?Thanks in advance!  

Hi all, I think this is a bug of CubeMX. Everytime the .ioc gets updated for the project, the code written for the descriptor characteristics get deleted in the SVCCTL_InitCustomSvc() of the autogenerated custom_stm.c file.I don't know if this issue is konwn or I am missing something while updating the .ioc file. Best Regards. 

I found something interresting.If we look at the STM32MP15XXAC (package TFBGA361) we can see that:DLCD_B1 is connected to K4 and Y17OTG_HS_ID is connected to Y17ETH_PHY_INTN is connectes to K4In this case, I need DLCD_B1 and OTG_HS_ID for flashing the eMMC with Linux. What I found is that ETH_PHY_INTN is actually connected to AC8 for the STM32MP157 dev-kit, and that leads me to the question:Is AC8 an interrupt or a wakeup pin for the Ethernet PHY? Why is AC8 selected? Should I declare it as an External Interrupt in CubeMX?If I look at CubeMX, there is an option for Ethernet Interrupt.   

Implement CAN Communication on STM32F407 discovery board using register level programming.In which we transmit some messages and receive same messages in loopback mode. Can you please write the code for this.

Hi, I've created a project in STM32CubeIDE 1.14.1 for the Discovery board B-U585I-IOT02A with TrustZone enabled. Unfortunately, I'm unable to select any of the TIM timers as the SYS_NS and SYS time source. They are disabled with the following message: "TIM6 disabled: This IP instance is already used or no context is selected."However, I activated the TIM6 timer with a Non-secure context enabled.Thanks in advance for your help!@STea 

Can somebody explain what is the hardware and software breakpoint ?When I add a breakpoint in STM32CubeIDE, what is the type of this breakpoint ?What is the difference between these two? 

For best EMC immunity and minimum cell current (need months of cell life), how to setup un-used pins of STM32WLE5JCI6?  The chip in a module with metal screen box.  Pins are 'broken out' to edge of module with pcb trace of a few mm.a. Should we program un-used pins as digital input (internal pull up, pull down or none), digital output (set to zero or one) or analogue input (seem minimum cell current drain as application note)?b. Should un-used pin connect to Vdd, Ground or left open (if it is digital output)?For EMC, the device should function properly near a cellular phone transmitting at maximum power (assume phone is far away from base station).  Phone is likely 4G or 5G (and 3G rarely).  Not sure if maximum transmit power differ?Many thanks

COMP2 is not listed on the configuration tool... eventhough it is well documented on the RM0455. Please provide directions to activate and use properly COMP2 on the H7A3

Hello,I am trying to evaluate the use of MCSDK in a dual-motor application.  Motor 1 works, but motor 2 does not.I have a fresh Workbench project, with both motors configured identically, with the exception of Over-Current Protection.  When I generate, I get a "NOTICE: Please disable the overcurrent protection of Stage 2 to avoid resource assignment conflict on COMP2.  The power state is already protected by STDRIVE101."  Under Current Sensing of Stage 2, I disabled Over-Current Protection, but still get the notice.The generated CubeIDE project compiles and uploads without issue.I use MC_FOC_SDK_2_Motors to try to start/stop the motors.  After connecting, I hit press Start on Motor 1.  I hear the PWM, and after a second (as expected), the motor starts ramping according to my startup sequence.  When I press Start on Motor2, I get no sound, and no motion.I analyze the outputs to the motor with a dual channel oscilloscope.  On Motor 1, U, V, W signa

We have been told Asymmetric Serial Packet Exchange Protocol documentation would be available with the release of MC Workbench V6. We're at V6.3 now. Can you direct me to where I might find said documentation?The old serial communication class available in MC Workbench 5.4.8 doesn't seem to work with the new Workbench versions.Here I sit at 5.4.8 wondering, where is the flying car I was promised?Thank you in advance.
