Solved

I used the STM32CubeIDE for 3 years on a Windows10 PC. After installing the 8-bit ST_Tools (STM8CubeIDE,...) on the same PC the connection to a NUCLEO-64 (STM32-G431RB) does no longer work. Now STM32CubeProgrammer reports "No ST-Link detected". However, I don't know if the STM8 installation is related to the problem.Solution attempt: download and re-install the latest STM32CubeProgrammer (v2.11.0) ST-Link drivers (STSW-LINK009). The install wizard reported a successful driver installation (see screenshot). However, the issue"No ST-Link detected" persists, and new drivers are listed by the Windows Device Manager (see screenshot).Please suggest potential solutions to try. Thank you.

I read in this document about the concept of BLE slot allocation. I experimented with 5 STM32WB boards, one as master the four as slaves), and encountered an error I didn't understand.The master issued `aci_gap_create_connection` to each of the four slaves with the following parameters:Common parameters:LE_Scan_Interval: 96 (which means 96 * 0.625 = 60 ms)LE_Scan_Window: 96 (same as above)Conn_Interval_Min: 48 (48 * 1.25 = 60 ms)Conn_Interval_Max: 48 (same as above)Conn_Latency: 0Slave1:Minimum_CE_Length: 0Maximum_CE_Length: 0Slave2:Minimum_CE_Length: 14 (14 * 0.625 = 8.75 ms)Maximum_CE_Length: 14Slave3:Minimum_CE_Length: 28 (28 * 0.625 = 17.5 ms)Maximum_CE_Length: 28Slave4:Minimum_CE_Length: 43 (43 * 0.625 = 26.875 ms)Maximum_CE_Length: 43If I understand the document correctly, the first connection (to slave1) will make the anchor period 60 ms, and the subsequent connections won't change that as Conn_Interval_Min and Conn_Interval_Max are the same for all connections.All four connecti

According to datasheet, STM32H7B0VBT have 1024Kb of AXI SRAM, it is defined in STM32H7B0VBTX_FLASH.ld. But for some reason the same memory is limited to 128Kb in STM32H7B0VBTX_RAM.ld. I modify linker scripts according to my needs, but maybe I missing something. Is it just an usage example, or there was some reason for assigning only 128Kb?

Does it have a linux driver and is it supported? How can I use it?

I'm using MSIS at 24 MHz for everything, like this: SET_BIT(RCC->CR, RCC_CR_MSISON); while (0 == (RCC->CR & RCC_CR_MSISRDY)); SET_BIT(RCC->ICSCR1, RCC_ICSCR1_MSIRGSEL); MODIFY_REG(RCC->ICSCR1, RCC_ICSCR1_MSISRANGE, RCC_ICSCR1_MSISRANGE_0);   // enable 32kHz clock crystal SET_BIT(PWR->DBPR, PWR_DBPR_DBP); // enable write access to backup domain MODIFY_REG(RCC->BDCR, RCC_BDCR_LSEDRV, RCC_BDCR_LSEDRV_0); // medium-low drive power SET_BIT(RCC->BDCR, RCC_BDCR_LSESYSEN); // enable propagation to other peripherals (like LPTIM4) SET_BIT(RCC->BDCR, RCC_BDCR_LSEON); // LL_RCC_LSE_Enable while (0 == READ_BIT(RCC->BDCR, RCC_BDCR_LSERDY)); // wait until ready   // use it to trim the MSIS oscillator MODIFY_REG(RCC->CR, RCC_CR_MSIPLLSEL, RCC_CR_MSIPLLSEL); SET_BIT(RCC->CR, RCC_CR_MSIPLLEN);   // set MSIS as system clock MODIFY_REG(RCC->CFGR1, RCC_CFGR1_SW, 0); while (0 != READ_BIT(RCC->CFGR1, RCC_CFGR1_SWS)); /* Wait until syste

Hello,actually, our processor STM32MP153 (dual core) is completely full with the "normal" memory regions regarding the MCUs (M4) code and data. So now, we decided to add the RETRAM_data form ORIGIN = 0x00001000, LENGTH = 0x0000F000 /*60k*/The linker works as expected but if I start a DMA transfer with variables placed inside this area, the DMA stucks directly with a transfer error. The same code but placed in the RAM1_dataORIGIN = 0x10030000, LENGTH = 0x00010000 /* 64K*/works fine.I know this problem only if the area is not accessible by the DMA as on the H7 but if I have a look at the memory layout and master/slave bus matrix, both DMA should be able to send data from the RetRAM.Any ideas what could lead to this problem? I checked also to place the segment at 0x38000000 but this leads to a linux boot stuck.My actual workaround is to place variables not used by the DMA into the RetRAM section .bss1 with the __attribute__((section (".bss1")))command. This works but, this is my next smal

I want to use CAN Bus in STM32F042F4 (TSSOP20). In the data sheet it says, CAN_RX on PA11 Pin 17, CAN_TX on PA12 Pin 18.When trying to configure in CubeMX, CAN function is greyed out and the pinout has not PA11 and PA12. Isn't it possible to use CAN in STM32F042F4 TSSOP20 device? Best regardsHarald

I want to use a STUSB4500LBJR for USB-C power delivery. On the datasheet stands that connecting the I2C lines is optional and in another datasheed of the STUSB4500 stands that I don't have to use a microcontroller. But I cannot find information about choosing a voltage output I want from the STUSB4500 on the internet.

Hi,I am using ST-LINK_CLI for flashing mcu via ST-Link ->SWD. In ST-Link utility can be set Reset mode (SW,HW,Core). How can I set this parameter in ST-Link_CLI ? I did not find anything in documentation.Or is there any better tool to control STLink via command line? Actually I use it to control it from python...Thank you, Jan.

I am currently working on a project to program a PLC. This one already has a program to control its operation. We are using the Nucleo board STM32F302RBT6. The goal is to extend the program to be able to integrate the uart communication. Unfortunately I can't configure the uart using the normal method on stmcubeMx because it would already damage the current control program. For the configuration I have chosen another method, that of copying all the lines of codes of configuration of the uart in my current program. In the files main.c, stm32f3xx_hal_msp.c and  stm32f3xx_hal_conf.h I added all the necessary configurations as they appear in the uart configuration with stmcubeMx. In addition I added the stm32f3xx_hal_uart.c, stm32f3xx_hal_uart_ex.c, stm32f3xx_ll_usart.h, stm32f3xx_hal_uart.h,  stm32f3xx_hal_uart_ex.h files in the drivers where they belong. Unfortunately the uart communication still does not work and when I compile my program I get the following error: Break at ad

Hi,I'm using the NUCLEO-64 STM32L476RG and I am aware that it is very simple to start the ADC to get a reading in an analog port. One should however wait for the conversion to complete and the HAL library has the HAL_ADC_PollForConversion() function that can be called with a timeout value.However, HAL_ADC_PollForConversion() enters in a loop until the ADC finishes conversion; and I would like to release the CPU to perform other tasks (in FreeRTOS) while the conversion happens.Thus, I am thinking about calling HAL_ADC_PollForConversion() with a 0 timeout value and call osDelay(1) if the return is HAL_TIMEOUT. (This would be repeated until the return is HAL_OK.)However, I noticed in the HAL_ADC_PollForConversion code that a timeout causes the following two lines to be called: /* Update ADC state machine to timeout */ SET_BIT(hadc->State, HAL_ADC_STATE_TIMEOUT); /* Process unlocked */ __HAL_UNLOCK(hadc);Would this prevent the ADC to complete the conversion process?W

In stm32mp157c-ed1.dts, the MPU pin setting is written in the stm32mp15-pinctrl.dtsi file, but in CubeMX, a node called @pinctrl is created in the generated .dts file and written in it.Why?Can I delete this part and create a ***.pinctrl.dtsi file?

I am having issues getting the status flag polling mode to work when I try to poll with a QuadSPI command that uses all four data lines for the instruction. When using a command with a 4-line instruction in this mode, it polls the first command correctly, but the second command has one fewer clock cycles than expected, and then the chip select never goes high again. I've tried getting this to work with multiple configuration settings, but the common denominator seems to be the 4-line instruction causing the issue. QSPI_HandleTypeDef hqspi = { .Instance = QUADSPI, .Init.ClockPrescaler = 63, .Init.FifoThreshold = 1, .Init.SampleShifting = QSPI_SAMPLE_SHIFTING_NONE, .Init.FlashSize = 1, .Init.ChipSelectHighTime = QSPI_CS_HIGH_TIME_1_CYCLE, .Init.ClockMode = QSPI_CLOCK_MODE_0, .Init.FlashID = QSPI_FLASH_ID_1, .Init.DualFlash = QSPI_DUALFLASH_DISABLE, };   QSPI_CommandTypeDef qspiCmd = { .Instruction = 0x05, .Address = 0x00000000, .AlternateBytes = 0x00000000, .AddressSize

From SBSFU examples, with default SECUSER memory setting except reading from OB registers, it is only protecting SBSFU area alone.Are we need to protect SBSFU + ACT_SLOT HEADER (1024 Bytes for H7) area as well right ??So what is your recommendation on protection of HEADER ??

Hi, I am looking to read 16bits which are split between port A and B on an interrupt hooked up to exti0. I *seem* to have the dma working and see the expected data at DMA completion (interrupt). However the DMA controller does not react to the interrupt quick enough and Im trying to compensate by triggering a little earlier and having the dma controller read a few more instances from A/B ->IDR. What I am stuck at is how I can get the data to output to an array of 32 words in a ringbuffer fashion. It seems circular mode limits itself to 4 words total. Which is not enough to grab the data I want. I also couldnt understand when DMA continues in circular mode while in the completion interrupt. Do I need to temporarily suspend DMA while in that interrupt to read the data or does DMA continue on clearing the pending bit?Should I be using a separate DMA channel to take Data out of sram and put it in a stack allocated array?Thanks!

Hello, I have a Nucleo L476RG which I'm using for different projects, and I never gave an importance to the offset addresses that are written before every register in the reference manual.Can anyone explain to me what are theses offsets.

I see numerous examples of 4-wire SWD without a reset pin connection.I come from the PIC world where there is always Data, Clock and Reset for a Pgm/Dbg interface.I bought a Chinese STLink-V2 programmer/debugger and it has a reset pin as well as data, clock, GND and VSS.Although, the Chinese STLink-V2 comes with a 4-conductor cable for attachment to my target.Do I need to connect the Reset pin?Also, anyone know of an Ap-Note that covers the electrical nature of the SWD interface.Thank You
