It seems that with CubeProgrammer all partitions in the MP1 EMMC must be flashed using the tab delimited file. Is there a way to support to update/flash only selected partitions ?

I want to use Comparator, for comparing external voltage with Vref in stop modeso that if external voltage is more than Vref, wake up from stop mode and do something.I read example code about Comparator, LPTIMER ... but they are not exact solution about my projectso Can you give some idea or example about Using Comparator in stop mode ?

Dear experts,I'm new to M7 (and H7) so pardon me for a stupid question.Created a new .ioc file in CubeMX 5.3.0 for STM32H753 EVAL2 board.There I can select debug interface as JTAG 5 pins or Serial wire (at least).From the Cube report file, in Serial Wire mode it uses 2 pins: PA14 SWCLKPA13 SWDIOWhere is SWO ? It should be PB3, but the report file does not mention it.In JTAG 5 pins mode it uses PA14, PA15, PA13, PB3, PB4.Now, in a .ioc file made by my hardware engineer, for a custom board with same MCU,the debug mode is JTAG 5 pins.But I cannot change it to Serial wire or even to Disabled.Any reason, why?None of these 5 pins are hmm... pinned.Serial mode uses two (or three?) of JTAG 5 pins, so it should be possible to reuse them?Is the JTAG config locked by some other component or mode selection?Or can it be a "feature" of the Cube ?We both have Cube 5.3.0 on Linux, Ubuntu,Thanks in advancePavel A.

I'm using a WB55 Nucleo board and setting up a BLE connection with a 2nd WB55 Nucleo board using aci_gap_create_connection(). The connection succeeds and I am able to transfer data between the 2 boards. I would then like to terminate the connection. I call aci_gap_terminate_gap_proc(0x40) to do this, but I always get a return value of 0x46, which corresponds to BLE_STATUS_NOT_ALLOWED. Any ideas why the call to aci_gap_terminate_gap_proc() fails? Or is there a different recommended way to terminate the BLE connection? Thanks...

Hi,I maked a .ioc project on STM32F103 used STM32CubeMX, and Enabled its CAN mastor mode, and Enabled CAN's all interrupts(RX,TX,ERROR). Then make a SIMULINK model link to the ioc file, and place a CAN_IT module into it. At this time, it tell me 'Configuration must be done before!', And in the CAN_IT module, the interrupts RX/TX/ERROR are unchecked and disabled.But! When I do same process on STM32F107/407/417/302/469, it is OK.Please help me. thanks.

The number of frames per second does not exceed 10. Will there be any performance improvements? Are there any tips?

In DMA mode, the DMA block does copying. In normal mode the controller does the copying. So which block does copy in interrupt mode?

Is external clock mode 1 and external clock mode 2 are available only for channel 1 of general purpose timer(Timer 3 specifically)?. Or other channels can also be configured for it?

I am trying to debug my M4 program on systemworkbench (eclipse) for the board stm32mp157c-dk2 and the host computer is ubuntu. I have set breakpoints in normal flow and also in exceptional flows in the program. Program works very well in debug and I can see the outputs via my qt program on linux side on mini display. But the flow never stops by breakpoints. The breakpoints have no effect. I am doing the following steps correctly. Please tell me what is missing or what I am doing false... build the project in eclipseselect production mode in debug configuration because the program is based on the example "OpenAMP_TTY_echo" give the ip address in debug configurationright click on project and select Debug As --> ST's STM32 MPU C/C++ ApplicationAnd this is the log on console when the debug startsOpen On-Chip Debugger 0.10.0+dev-01124-gbfb41e6 (2018-11-16-15:00) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html debug_level: 1 cortex_a interrupt ma

I am trying to find a few KB of permanent storage on the STM32F303 part.The TRM mentions the flash map and the HAL seems to have some API's. However, I am unable to find any decent material on storing user data on flash.Is there any good example of this? Also, Is there a HAL API to get the UID of the part??

Hello,I have found some bugs in linker scripts generation when creating a project from CubeMX. Those bugs appears only when code is generated for STM32CubeIDE, related to linker scripts:/* Highest address of the user mode stack */ _estack = 0x20040000; /* end of "RAM" Ram type memory *//* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 256K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 1024K }_estack should be set to 0x2003000, otherwise the system goes into hard fault.RAM_SHARED section does not appear, without it the coprocessor is unreachable I guess.MAPPING_TABLE, MB_MEM1 and MB_MEM2 are not mapped to RAM_SHAREDOn the other hand, if I generate a makefile or TRUEStudio project for stm32wb55cg (1 MB of flash), the linker reports only 512 KBHope to see this fixed, thanks for your help!

Posted on April 11, 2018 at 13:31Dear Cube team,Just noticed that STM32CubeMX v 4.24.0 does not show correct mode for GPIOs in pinout view (the main nice GUI).On the picture below, PF14 is GPIO input with pullup, but the flyout tip shows as (no mode).Would like to see the actual mode there.Thanks,-- pavel#stm32f4 #cubemx-v4.24

I am currently working with UART in DMA mode for CLI implimentation. I would like to do some string parsing as part of the HAL_UART_RxCpltCallback.Is this callback running in IRQ context or outside of IRQ context ? Is this the correct place for post processing IRQ data ? What would you recommend ?

Hi,I have design a custom board with the STM32F207VE. But I made a mistake in routing the UART TX as RX and UART RX as TX. Is there a way to change the STM32 UART TX port to an RX through the software?

I’m trying to get my STM32H743 to communicate with a Cypress S25FL128S.I want to change the state of the Configuration register bit 1 from the default of zero to a one.I want to use the HAL_QSPI API to perform this write but I’m confused on how to add two byte command sequence.Instruction WWR = 0x01QSPI_CommandTypeDef my_qspiCommand; my_qspiCommand.InstructionMode  = QSPI_INSTRUCTION_1_LINE; my_qspiCommand.Instruction      = 0x01; my_qspiCommand.AddressMode      = QSPI_ADDRESS_NONE; my_qspiCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE; my_qspiCommand.DataMode         = QSPI_DATA_1_LINE; my_qspiCommand.DummyCycles      = 0; my_qspiCommand.DdrMode          = QSPI_DDR_MODE_DISABLE; my_qspiCommand.DdrHoldHalfCycle = QSPI_DDR_HHC_ANALOG_DELAY;&nbs

Hello all, I tried to integrate the Gauge and Graph examples (from the repository) into my project, but both (separately tried) result in a lock up of the system as soon as the components are generated in the view class.I took care to include the call for "setupBuffer "at the end of touchgfx_init and included the following lines:   #define CANVAS_BUFFER_SIZE (3600*3)   static uint8_t canvasBuffer[CANVAS_BUFFER_SIZE];   CanvasWidgetRenderer::setupBuffer(canvasBuffer, CANVAS_BUFFER_SIZE);I copied the code from the template view into my own screen view class without further modification.When I debug the code in the embedded system, the system hangs as soon as I enter the view. The call stack shows that it sticks in PainterRGB565::PainterRGB565 (color 0x00, alpha 0xFF).Any ideas what could be the reason?

I have a ST-LINK / V2 programmer that I bought 4 years ago and it works perfect. I recently bought two new programmers but none work with the same connections like old programmer. I updated each firmware but it still doesn't work. Has anything changed in the new programmers? In document of ST-Link i haven't seen any change in hardware. my hardware is as followed: MCU Programmer SWDIO (PA13)-> SWDIO (Pin 7) GND -> GND (Pin 20) 3.3V -> 3.3V (Pin 19) SWCLK (PA14)-> SWCLK (Pin 9)

Hi ST , I have 100 qty of STM32L4R5VG with bootloader version 9.2 which is fault bootloader . AN2606 says that the bootloader version 9.2 has a trouble with system reset repeatably so can not be used for bootloader.  I tried to fix this issue by myself, but I found there is no solution from this Q&A : https://community.st.com/s/question/0D50X0000BTbseCSQR/stm32l4r5vg-bootloader-version-92-not-working-only-system-reset-repeatablyHow can I exchange the fault STM32L4R5VG with normal bootloader V9.4 or STM32L4R5VI ? What's the process to exchange ?

Hello,I'm trying to get the MEMS microphone (components U21 and U20 on the STM32F746g-disco) to work with SAI. I save my microphone inputs into a buffer with 1000 8-bit values via HAL_SAI_Receive_DMA. Below I have written my MX_SAI_Init() and HAL_SAI_MspInit(). I realise that the slots in the SAI audio frame are important, and from what I have learned I have initialized 4 slots with 2 active, 1 and 3.As of now, the input buffer fills every adress with the value 255. I have been looking around the forum for quite some time and gotten a bit further, but it would be very helpful if someone with more experience with SAI could give me feedback on my initialization. Is this initialization correct in order to get input working with the MEMS microphones?Initialization code static void MX_SAI1_Init(void) {   hsai_BlockA1.Instance = SAI1_Block_A; hsai_BlockA1.Init.Protocol = SAI_FREE_PROTOCOL; hsai_BlockA1.Init.AudioMode = SAI_MODEMASTER_RX; hsai_BlockA1.Init.DataSize = SAI_DATASIZE_8;

On the first power on, Graphical demo ran. After running GPIO example program provided in the STM32H7 FW package, IAR complains that No STM32 MCU detected. Same issue with the STM32CubeProgrammer tool. Why is this board is difficult to work compare to other ST boards?
