STM32 MCUs

I am working with a dual core STM32H755 and attempting to create a shared memory location for the two cores to access. I am attempting to do this by modifying the linker script.  I have added the following lines to the M7 core linker script, in the SECTIONS block:/* Shared Memory section for inter core comms */ .sharedRAMsection 0x30040000 : { .= ALIGN(4); KEEP(*(.sharedRAMsection)) . = ALIGN(4); } > RAM_D2 Then in one of my .c files, I have declared the following global variable:RegisterMap_t __attribute__((section(".sharedRAMsection"))) g_RegisterMap; However, when I debug I can see the address of this variable has been assigned to memory location 0x24000064, as seen in the watch window: I am using visual studio and visual GDB, and I am debugging with 2 separate VS instances for the two cores. Is there something else that I need to do in order to get this variable into the correct memory location? Thanks 

I am currently making an artificial horizon for a project in TouchGFX, but I just noticed that when I tried to use the svg of the Pitch_Angle_Indicator that has numbers I get a compile error. Are there any plans to implement the usage of numbers in svg images? BSNeyus 

用SPI+DMA驱动AD4001，用片选信号代替 CONV，采集一个正弦信号。Normalnormal正常，循环模式却不对，求大佬解答！！Normal模式下，每次在 HAL_SPI_RxCpltCallback 函数里面重新启动数据正常，能看到正弦变化规律                                 循环模式下数据就不对了，采集的同样一个交流信号，我在半传输完成回调里面查看，按道理后半部分的数据应该是正常的正弦变化才对，实际却不是，但是去采集直流时又是正常的。                PS：缓冲区开的1200，感觉应该不会更新这么快，就算更新应该局部的数据具有正弦规律    我得猜想：是不是因为我再keil里面是打断点查看的数据，并不会停下SPI+DMA 在循环模式下的硬件工作，导致后台一直在更新，keil显示的数据其实不对配置：配置的区别只修改了DMA是正常还是循环void MX_SPI1_Init（void）{/* 用户代码开始 SPI1_Init 0 *//* 用户代码结束 SPI1_Init 0 *//* 用户代码开始SPI1_Init 1 *//* 用户代码结束 SPI1_Init 1 */hspi1.实例 = SPI1;HSPI1 的。Init.Mode = SPI_MODE_MASTER;HSPI1 的。Init.Direction = SPI_DIRECTION_2LINES_RXONLY;HSPI1 的。Init.DataSize = SPI_DATASIZE_32BIT;HSPI1 的。Init.CLKPolarity = SPI_POLARITY_LOW;HSPI1 的。Init.CLKPhase = SPI_PHASE_1EDGE;HSPI1 的。Init.NSS = SPI_NSS_HARD_OUTPUT;HSPI1 的。Init.BaudRatePrescal

Hi guys,I am using the USB 2.0 port (in CDC mode),  based on STM32G474 microcontroller design project for the communication with PC. I am trying to debug/upload the project using the usb port but it shows the message like  "No ST-LINK detected!!! please conncet the ST-LINK and restart the session." I have tried to upgrade the st-link frimware from the help menu but it shows nothing in upgrade GUI (no st-link shows in device list). Currently i am using  version1.18.0 stm32cubeide. I also tried to upload the file using stm32CubeProgrammer tool but there also "no debug probe detected" in st-link mode. In fact usb port is communicating with the serial terminal (from serial  terminal to - microcontroller and vice a versa) after uploading the firmware in it using SWD interface.Could you please help me in order to short out this issue.?Many thanks. 

Hello Tesla I need to run M4 from 0x08000000  and then M7 from 0x08100000. Is there any example ?   Exactly I v'done my BOOT that runs on M4 (0x08000000) loads the Flash , then jumps into M4 (0x08040000). Now i have to run M7 from 0x08100000, but i don't know how... Please help :)

Hello, I am asking for help from the community. My application is completely written, but I can't set read protection. I tried to do all the steps in this guide, but it led to bricking one of my boards. The second board is still in product state = 17? but I can't install the obk file or remove protection, returning it to the ED state. Cube programmer did not give me the choice "Change the PRODUCT_STATE option to 17, then press [Apply]. A window appears asking if the default DA-Config should be applied, press [NO]." it just set the state to 17 without asking.I did not find any sensible information on the network on how to set or remove protection. Maybe it is possible to do this directly from the application? in state 17 I can flash h503, but I can't switch to debugging.I really ask for help, my project is completely ready, but it needs to be protected.

Hi. I am programming a board with STM32G0, which is battery powered. All processor pins are used. Overall, the device works without any problems. In normal operation mode, only STM draws about 3.5mA. However, I wanted to put the device to sleep and:1. In Shutdown mode, STM draws 40nA (according to the documentation), and the entire device 720uA, which is satisfactory for me, but I want to be able to wake it up from a dozen or so GPIO pins, so I tried to start Stop mode and:2. In Stop mode, STM draws 600nA (more than the documentation indicates, but still quite good). I have the ENABLE pins of the additional LDO and charge pump connected to the PB9 pin through 100R resistors, which are on the PCB and power other systems. There is also a 4k7 pull-down on the ENA pins. During normal operation, PB9 is in a high state, and before sleep it is set to a low state to turn these systems off. And here comes the problem: when I leave PB9 in the high state before switching to Stop mode, the cu

I'm using an STM32WB5MMG module.I was facing a problem with AD not working properly when exiting from stop2 mode.HAL_ADC_PollForConversion()returns a value other than HAL_OKAnd,HAL_ADC_GetValue(&hadc1)returns only 0.I have confirmed the same problem in the following post, but it remained unresolved, so I would like to know how to resolve it.https://community.st.com/t5/stm32-mcus-wireless/how-to-get-adc-to-work-after-stop0-mode-stm32wb5/td-p/95710Similar to this postBefore entering STOP2 mode, tried to doHAL_ADC_DeInit(&hadc1);and after exiting from STOP2 mode, tried to doMX_ADC1_Init()But, The process in this function below had error.if (HAL_ADC_Init(&hadc1) != HAL_OK) { Error_Handler(); }Is there any approach I should try?

I am trying to implement a GPDMA driver in a C project that does not use HAL, and have been really struggling to get something working. I have read everything I can find on this peripheral, multiple times, and still don't quite understand how one would configure the registers without using HAL. The goal is to get circular DMA transfers from peripheral to memory (e.g. ADC to memory). The H5 reference manual gives this figure, which conceptually makes sense to me but I can't figure out the implementation.It seems like it should be relatively simple to setup in C with direct register access instead of HAL configuration structures, but I have not been able to find any examples online or in documentation. I am wondering if anyone has gotten a linked list GPDMA transfer working without having CubeMX + HAL do all the work?

I am trying to debug some functions to write to the memory mapped QSPI. When I go to debug it, I notice that before any functions even run the QPSI is in HAL_QSPI_STATE_ERROR, therefore I cannot test my code to see if is running because it is dependent on the State of the QSPI. My QSPI is a WinBond25Q128JVSQ. Is there a way to trouble shoot this?

I am looking for help solving a CDC-ACM problem with Azure Rtos ThreadX, and the USBX Middleware for STM32F4.My device is an STM32F427VGTx.I currently have a project that uses the USBX host library. I am connecting up to 4x CDC-ACM devices through an off-the-shelf USB Hub.I had problems connecting multiple devices through the hub, but I have solved that after following the solution to update the USBX core bsp from the stm32-mw-usbx repo. (STM32H7 and USB2514 Continued Problems) I can connect to all 4x CDC-ACM devices (data class instance and control class instance enumerate successfully on all devices).I can send commands to all devices using the control interface by sending a transfer request to the control endpoint.I can read from up to two CDC-ACM devices, but the third and fourth device will timeout after calling ux_host_class_cdc_acm_read. The function returns a transfer-request-timeout after failing to retrieve the ux_host_semaphore. The status of ux_host_semaphore_get is al

Are the steps followed for RTC calibration the same for crystal and temperature variation?How is the calibration register value selected for temperature variation?

I have selected the RTC calibration as 512Hz. Will I be able to perform RTC smooth calibration if my frequency obtained on the RTC calib pin is beyond the range 511.75Hz - 512.25Hz. How do I calibrate the RTC beyond this range ??  

When we generate the PWM pulse in all GPIOP's, if any of the 2 ports or more having interconnection, how to identify or recognize by using the PWM pulse?   

Hi, Recently I have mistakenly upgraded to FUS 2.0 and BLE stack 1.22.1 for my stm32wb5mmg chip. I was using FUS 1.2.0 and BLE stack 1.22.0.2 before and the system behaves perfectly fine with the firmware on hand. After upgrading it the device doesn't seem to be advertising and couldn't be detected by any other devices. I have notice that it is impossible to downgrade the FUS version is there a way to tackle the issue? If I wanted to erase the whole chip and copy the memory of a working chip, is that possible?

When trying to program the STM32L4P5RE, I get an assertion failure when trying to program the second bank like this:HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, address, data)This call fails if my address is in the second bank `0x08080000`.  Looking at the source code, I get an assertion failure here: static void FLASH_Program_DoubleWord(uint32_t Address, uint64_t Data){ /* Check the parameters */ assert_param(IS_FLASH_PROGRAM_ADDRESS(Address)); <---- HEREI understand when DBANK (Or DB1M) is set, we cannot read the other bank.  So how are we supposed to actually program it?

Hi all,I'm working on a BLE project on STM32WB5MMGHx module on each side (client and server).For the server side, I use CubeMX to generate almost all the code (pairing configuration, GATT service and characteristics, etc.). I managed to "bypass" some CubeMX generated using the USER CODE comment areas to do what I wanted.For the client part (more complex), I can only get a Custom P2P Client (this not what I want). Looks like I can't disable the Custom P2P Client (combobox disabled).So here is the questions :- How am I supposed to use CubeMX to create the BLE client with some custom code without bypassing 90% of CubeMX generated code (if possible...) ?- Should I create all the projet manually and integrate some CubeMX generated code (in another folder) by hand ?  Thx

Ok, a quick set of questions. (1) STM32U5G9 has 2 AHB ports for GPU2D. M0 goes throu DCACHE2, M1 does not. Which type of request (command list, texture fetch, render/blend read/write) for throu which port (M0/M1) ? (2) Is there any documentation available for TSC4/TSC6/TSC6A other than US Patent #9640149 ? (3) Is there any documentation available for the TSVG formated used for nema_vg_draw_tsvg() ? (4) Where can I get nema_font_convert, nema_vg_font_convert and nema_pixpresso for Linux/Windows/Mac ? Really appreciate any help here. There was talk about a NeoChromSDK, is there any news on thise one ?   

Hello Community,I’m working on a custom board using the STM32G474VET3 MCU and encountering an issue with the ADC readings. I’m consistently getting a raw value of 4095 on all the ADC channels I’m using. It seems like something might be misconfigured, but I haven’t been able to pinpoint the cause.Any insights or suggestions would be greatly appreciated.Thank you!

Hi, guys,     I've bought STM32H745I-DISCO board to make an EtherCAT master, so I successfully employ EtherNet controller, USART3 for debugging but SPI2 has a problem. (I'm mostly novice fir H745)     I decided to use SPI2 for communication with external STM32F4xx controller, which exchanges 26 16-bit words with H745 board within 10kHz time frame, so it's a bit loaded communication. The attached picture renders the snapshot from logical analyser. 4 upper lines are SPI lines, other 3 lines are GPIOs used for debugging purposes - to show interrupt work.    The picture clearly shows that physical lines exchange data - I see expected 26 16-bit words from F4xx and data sent from H745 - in all cycles the picture is the same. But in reality I see only one time words from 4 to 22 in receive buffer (other appears to be zero), after that they are not updated at all. So receive is fault always. SPI2 is used in DMA mode via library function (code is below),

Hello, I am working with an STM32G4 microcontroller and noticed an unexpected behavior regarding Bit 20 (BFB2) in the User & Read Protection Option Bytes.According to the reference manual, BFB2 is a read-only bit.After performing an option bytes erase in Keil, I expected BFB2 to be cleared to 0 (default).However, after a system reset, I observed that BFB2 is set to 1.I would like to understand:Who sets BFB2 to 1 after an option bytes erase?Is this controlled by bootloader behavior, internal flash controller logic, or some default hardware mechanism?
