STM32 MCUs Software development tools

Hi,I have an application running on STM32F429ZIT6 using USB stack to communicate with PC client.MCU receives one type of message of 686 bytes every second and receives another type of message of 14 bytes afterwards with 0,5 secods of delay between messages. The 14 bytes message is a heartbeat so it needs to replied by MCU.It happens that after 5 to 10 minutes of continuous operation, MCU is not able to send data because hcdc->TxState is alway 1, ie, busy. Reception works fine.During Rx interruption, application only adds data to ring buffer, so that this buffer is later serialized and processed by main function.static int8_t CDC_Receive_HS(uint8_t* Buf, uint32_t *Len) { /* USER CODE BEGIN 11 */     /* Message RX Completed, Send it to Ring Buffer to be processed at FMC_Run()*/ for(uint16_t i = 0; i < *Len; i++){ ring_push(RMP_RXRingBuffer, (uint8_t *) &Buf[i]); }     USBD_CDC_SetRxBuffer(&hUsbDeviceHS, &Buf[0]); USBD_CDC_ReceivePacket(&h

When using STM32CubeProgrammer and Silicon Labs CP2102 for USB-UART bridge, DTR state does not become "1 (Low)" when read unprotecting. No problem with FTDI FT232RQ.Our system uses DTR for RXD control, so if DTR is 0 (High), communication is not possible.Is it possible to fix STM32CubeProgrammer?

I am currently working on a project that will use a STM32L452VET3 when the product is deployed. The PCB for the product is still being laid out, so in the meantime, I have a Nucleo board that has an STM32L452RET6 that we will use to develop and test the embedded application.Given that the two MCUs are of the same family, I don't want to have two separate projects that are 99% identical, but I need to keep an .ioc file for both devices. Is there a way to have the .ioc output to the same Drivers/Core/Middleware directories and then conditionally compile for one target or the other (or something to that effect)?Thanks in advance.

I have a custom board using a STM32F446RET6 with a SD micro card slot.The card is formatted to exFAT with one partition.Using STM32CUBEMX V6.6.1 with firmware F4 V1.27.1For testing I have a minimal configuration as follows:SDIO  Mode SD 4 bits Wide bus  DMA enabled for RX and TX  SDIOCLOCK divide set to 4  SDIO global interrupt enabledUSB_OTG_FS  Mode is Device Only  USB OTG global interrupt enabled USB_DEVICE  Class for FS IP = Mass Storage Class  MSC_MEDIA_PACKET size is 512 bytes (I have tried increasing this)MCU  clock 168 MHz  using 12 MHz external crystal  SDIO clock is 48 MHz  USB clock 48 MHzRunning this setup when I plug a usb cable to the board the following shows in the log:usb 2-1.6: new full-speed USB device number 67 using ehci-pciusb 2-1.6: New USB device found, idVendor=0483, idProduct=572a, bcdDevice= 2.00usb 2-1.6: New USB device strings: Mfr=1, Prod

Hello, Updated CubeMX as well as H7 libraries, and now see problems with clock configurator, as well as some LL function calls in system clock init has no definition !STM32H743XI should have 480MHz clock...  And if we generate code, we get problems like this : (H7 V1110) LL_PWR_EnableRange1BoostMode();Error[Li005]: no definition for "LL_PWR_EnableRange1BoostMode"

I've used Keil for the last year - and they have a feature where I can view the flash memory while debugging (and even change it)I can't seem to find that with CubeIDE. Is there a way to see flash memory? I want to read/write and confirm it's there, etc.

Update: To get it to work, do a fresh install of the IDE, untick the CDT site in "Available Software Sites" (Help->Install New Software then "Manage"), and then install DevStyle from marketplaceSister issue on the Genuitec forum site: https://www.genuitec.com/forums/topic/devstyle-not-installing-in-stm32cubeide/I use STM32CubeIDE with the DevStyle Darkest Dark Theme extension from Eclipse Marketplace on two different 64-bit windows 10 computers without problem.Over the past couple of days, I've been trying to install the same plugin on a different 64-bit windows 10 computer but it doesn't seem to work.After a fresh install of STM32CubeIDE_v1.11.0_13638_20221122_1308, I do the following:Click Help->Eclipse Marketplace....Search DevStyleClick Install beside Darkest Dark Theme with DevStyle 2022.6.13aThen I leave the default components selected and I click on the Confirm button: after processing the click for about 20 seconds, I get the following error displayed:The installatio

After the update I have number of issues with debugging.The code written on the pervious version seems working as intended but when I try too peek the values of some variables (e.g. uwTick) I get broken results.most obvious bug - order of variable in the live view:another issue - wrong reported values. I tried to put in code the line A = A + 10;and the live view shows that every time the actual value is increased by 2560 (confirmed that A++; sometimes increments by 256 instead of 1)sometimes it works as intended, restarting debugging session few times somehow fixes the issue, but it is really annoyingfor reference, I use STLINK-V3SET with custom board based on F407 at 168MHz, and I have never had any issues with the hardware before today.

Hi,The STM32CubeIDE verison is v1.7.0, and now I found it perform full build every time when I click the build button, but I have just built it and didn't modify the source file.So how to do the settings?A full build takes too much time!Thanks!

I've just updated STM32CubeIDE to version 1.11 and the labels are no longer coloured (green comments, purple "void" etc.) and I can't even find the hammer-shaped "build" button at the top to check if the code is working.By the way, during installation of the update (performed by clicking 'help'-'about stm32' - 'installation details' - 'update') a pop-up appeared warning me that some installation files had an unknown source and asking me whether to proceed or not Furthermore, I can no longer even create a project as I have always done with previous versions 'file'-'new'-'project' creates a simple empty folder without even allowing me to select the MCU etc.

I have a stock version of Eclipse and I am trying to configure it to load and single step a very simple blinker that runs on an Nucleo-L073RZ board. The debug agent is stllink (aka texane, I am *not* using OpenOCD). The setup works as expected when debugged with arm-non-eabi-gdb alone.In Eclipse I can compile the simple application. I then create a debug configuration choosing "GDB Hardware Debugging". Under the debugger tab I choose the debugger (arm-none-eabi-gdb), and under the remote target fieldset I choose ST-LINK and the IP/port to talk to the agent. Under the Startup tab I set a breakpoint at "main" and I run the debugger.From the looks of it, the program is downloaded, Eclipse is aware of the breakpoints that I placed in the .gdbinit file (see attached screenshot), the blinker runs for a very short time (enough time to see the LED blink a few times over the course of less than a second) and then bails out with the result shown in the attached picture. The fact that the LED bli

Hello,I've created a new project and it seems like code wasn't generated as it should.Modified only clock configuration and added FREERTOS to my project.I think here tasks should be started, instead I have duplicate for header:Is it normal, have I missed something?Best regards,Krzysztof

Hello,I have read hall_CAN.c instructions and did everything that is stated there. In CubeIDE I have set Prescaler to 24 and both Quantas to 4 times. My Baud Rate is 250000 bit/s. I am using two same boards (Nucleo 746ZG) with CAN bus transciver MPC2551. After setting up everything board didn't want to send any can message. After some trouble shooting I have managed to find a bug in HAL library. Now I can send messages but I cannot receive them. I have logic analizer so I can check this data. I think there is a problem in inicialization since I cannot get any message in FIFO callback. Everytime I check there is 0 messages pending. I cannot figure this out so hopefully someone smarter can help resolve this issue. Thanks!

We are using STM32U575VGT6 MCU with 1 MB Flash(Two Banks of 512 KB).We are using entire flash as a single bank, by unchecking DBANK bit in Option byte).Start address of My image is 0x08000000 but when image size exceeds 0x8000(i.e. image spread across both bank), Then STM32CubeProgrammer write only upto 0x0807FFFF. (Facing same issue when download using IAR ).Then i tried to debug further and found that if i follow following steps then its work.Erase entire flash using STMCubeProgrammer (Full Chip Erase)Download the image(downloads succeeds with both IAR/STMCubeProgrammer).Repeat step 1 and 2 to re-download.Please help me to resolve the issue so that i would not require to erase entire flash every time manually. I think programmer shall erase all sectors of image and download the new image with out needs to be erase manually.For you info using ST link V2 programmer Thanks in Advance!!

In a STM32 project using FREERTOS with CMSIS V2, there is not automatic generation of thread creation calls in main function, likedefaultTaskHandle = osThreadNew(StartDefaultTask, NULL, &defaultTask_attributes);Is it supposed to be the programmer who now has to add these instructions, or can STM32CubeIDE be instructed to generate this code automatically, as in previous versions?

I am using custom designed board having STM32H745BIT6 and 25MHz external crystal with LDO Only as Power Selection from RCC settings.I am trying to check UART4 with pins PC10 and PC11 and flow control disabled.So Transmission is working well using Polling and Interrupt mode but reception is not working when using Interrupt or DMA mode. Reception is working in Polling mode.Attaching .ioc file for reference.Please check and suggest a way to resolve this issue.

I am trying to read data from a sensor in the background(using DMA) using I2C. Below the I2C DMA settings on CubeMX. The problem is that it shows a frozen measurement on the debug window although in the blocking mode the measurement floats all the time. Which setting I could have missed? void QMC7983_read_temp (void){ uint8_t status_flag = 0xFF; uint8_t raw_temp_data[2]; HAL_I2C_Mem_Read_DMA (&hi2c1, QMC7983_ADDR,STATUS_REG_1,1, &status_flag, 1); if((status_flag & 1U>>0)!=1) while(1){} HAL_I2C_Mem_Read_DMA (&hi2c1, QMC7983_ADDR,TOUT_LSB_REG,1,raw_temp_data, 2); temp_meas = (int16_t)(raw_temp_data[1]<<8 |raw_temp_data[0])/100.0; }     int main(void) { HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_TIM1_Init(); MX_I2C1_Init(); MX_ADC1_Init(); QMC7983_config(); HAL_Delay(100); QMC7983_read_temp (); while (1) { } }

Hi,I am attempting to jump to system memory to be able to update the firmware via UART. Due to design constraints, BOOT0 pin will not an option for accessing the bootloader thus jumping to system memory within the application is needed.I'm using the following code to jump to system memory: __enable_irq(); HAL_RCC_DeInit(); HAL_DeInit(); SysTick->CTRL = 0; SysTick->LOAD = 0; SysTick->VAL = 0;   __HAL_SYSCFG_REMAPMEMORY_SYSTEMFLASH();   const uint32_t p = (*((uint32_t*) 0x1FFF0000)); __set_MSP( p );   void (*SysMemBootJump)(void); SysMemBootJump = (void (*)(void)) (*((uint32_t *) 0x1FFF0004)); SysMemBootJump();In AN2606 there is a note for MCUs that use the dual bank feature, I believe this is the part that is preventing the system from bootloading correctly. I jump to system memory in main() and using STM32CubeProgrammer attempt to connect via UART. However, it timeouts since there is no response from the ST chip.I've tried this code both on my dev kit and custom

STM32CubeIDEVersion: 1.9.0Build: 12015_20220302_0855 (UTC)Processor: STM32H7My issue is when i start debugging my project, it crashes while configuring my System Clock Config, but there is no real error. The debug just says "Target Lost" and tries to reconnect but cannot. It always crashes at lineMODIFY_REG(RCC->CFGR, RCC_CFGR_SW, RCC_ClkInitStruct->SYSCLKSource);What is interesting is it works fine on my nucleo (STM32H743) but not on my board I layed out. So that would seem to point to a hardware issue on my side, but what could that be? I tried pulling the crystal (x3) off the nucleo just to see if it would cause the same problem, it still runs (granted the application part doesnt but thats to be expected). Anyone seen this issue before?

Hello!i am working with the STM32H747, i have a cubeMX generated project which uses LWIP for ETH connection and managment.I've encountered an issue - i have a LWIP tcp server, which connect clients and runs properly. when i disconnect the ethernet cable with out disconnecting rom client first i am not able to recover connection after the cable is reconnected. the only thing that works is restating and this is not an option.Please advise on possible ways to resolve this issue :)thanks
