Hello!Having some issues getting this to work, is it even possible with this setup?PB3 (connected to the JTAG connector) has been reassigned to "SYS_JTDO_SWO", and core clock is at 168MHz.A schematic of the EVAL-boards JTAG connector is available on page 6/24 in this pdf:https://www.st.com/content/ccc/resource/technical/document/user_manual/11/80/94/38/c9/d5/4a/02/DM00075652.pdf/files/DM00075652.pdf/jcr:content/translations/en.DM00075652.pdfJP3 has been tested in both open and closed configurations.The ST-LINK/V2 documentation gives this pinout ( page 12/19):https://www.st.com/content/ccc/resource/technical/document/user_manual/65/e0/44/72/9e/34/41/8d/DM00026748.pdf/files/DM00026748.pdf/jcr:content/translations/en.DM00026748.pdf In CubeMX, under the SYS tab, debugging is configured to "Trace Asynchronous Sw", as seen in the image below. JTDO (JTAG connector pin 13) is hence reassigned to SWO.The clocking is configured as:Debug settings in STM32CubeIDE is:And SWV settings as below:After

Dear all, dear stm,we ported our project from stm32F427 to stm32F765 because we needed more RAM.After this we noticed that our code execution time has more than doubled.We check all twice, ART, Cache, Interrupt, PLL, etc.We tested also the Overdrive with no effect.What could be the reason that the code execution from internal flash from stm32F7 is little more than two times slower than from stm32F4?We are using Keil ARM Compiler V5.06 update 6.Best regardsDirk

Is there any plan to provide Unique Device ID registers, together with second calibration point for Temperature Sensor in STM32G030xx?Initially, I expected these data being missing in stm32g030xx.h and DS by simple mistake. I really miss these 2 features. I tried to find some data in memory, but every access generates Hard Fault and I gave up.

I have a SPC584B-DIS discovery board, and I can see that on the Matlab website it's listed as being supported hardware for Simulink.I have been trying to understand how exactly it should work though. I can see that most (all?)of the Simulink blocks are for STM32, and require an .ioc file generated with STM32Cube in order to link the hardware correctly. I understand that STM32Cube doesnt have anything for the SPC5 chips, and so I am wondering if there is a different method for working with them, or if they are not really supported as advertised by Mathworks? https://de.mathworks.com/hardware-support/stmicroelectronics.htmlThis is the site im referring to. It does say "With the exception of the Nudeo and Discovery Boards, MathWorks does not offer an Embedded Coder Hardware Support Package for the devices listed on this page. " But again, I do have a discovery board and so I thought it would be covered. Can someone shed some light on how to approach this?

Hello,We are having trouble reading FUS version using STMprogrammer application.0x20030030 always returns 0.The interesting bit, is that SHCI_GetWirelessFwInfo() API does return 1.1.0 as FUS version as expected.FW version is 1.5.0.Its either issue with the documentation (address changed?), or with programmer application.Any ideas?./STM32_Programmer_CLI -c port=SWD mode=UR -r32 0x20030030 1 ------------------------------------------------------------------- STM32CubeProgrammer v2.2.1 -------------------------------------------------------------------   ST-LINK SN : 31FF6B065248393731200143 ST-LINK FW : V2J36S7 Voltage : 1.82V SWD freq : 4000 KHz Connect mode: Under Reset Reset mode : Hardware reset Device ID : 0x495 Device name : STM32WBxx Flash size : 1 MBytes Device type : MCU Device CPU : Cortex-M0+/M4     Reading 32-bit memory content Size : 4 Bytes Address: : 0x20030030   0x20030030 : 00000000

Dear community,about a year ago i have bought a kit: 32F769IDISCOVERY and only now have started to get acquainted with it. Following the instructions in book by Carmini Noviello i have installed all the requered software (including CUBE as a programmer).I still have not got STM32 blinking with LED.As I started with evaluation board, there was original software on it for demonstative purposes (interacting with touchscreeen)Before I wrote my own first compiled program to MCU, I have read out the program from MCU and saved it as .bin file.My own simple program faild to run (another story) and I could write an original bin to MCU and it was running ok. However, after a certain time it stopped workking (upon writing it told me that CPU is locked up) (both programmators Cube and STMUtility). As one of the the first steps I am trying to find the original compliled .hex with demonstrating program (STM32769I-DISCO_DEMO_V1.0.0_FULL.hex) mentioned in internet and manuals.In manual it is stated to

Hi, I am developing a USBPD system with STM32G071KBU6N. This MCU has a USBPD port. I am trying to use it to build a PD SNK port to get a PDO 20V/3A, 12V,3A,, 5V/3A. However, the code was stuck in the Hardreset section. In the debug section, When the USB is plugged, it jump to Hardreset section.I can see the Hard reset status is USBPD_HR_STATUS_COMPLETED. Even the status is completed, the system still try to do the hardreset for a few times. After that, the notification message turn to USBPD_NOTIFY_POWER_SNK_STOP and then USBPD_NOTIFY_PE_DISABLED. Seems that the whole USBPD system is closed. Even I unplug and plug again the USB, the attach and detach event cannot be triggered.I checked again the USBPD negotiation AMS, in the hard reset section, the USBPD_NOTIFY_PE_DISABLED shouldn't be shown. is there any features I didn't handle in the usbpd_dmp_user.c/ usbpd_pwr.c causing this issue? As I didn't have the development tool, I cannot access to the USBPD GUI.

Hi , in ST25R3911B , as mentioned in datasheet in section 3.4 Electrical specifications, Table 10.1 , to enable the power down mode , setting following registers , will it make to power down mode ?"Register 00h set to 0Fh(no clock on MCU_CLK), register 01h set to 80h (3 V supplymode), register 02hset to 00h register 03hset to 08h, other registers in default state."I am modifying this registers as soon as we read data from card.And next time when we want to read the card , repeating all initializing sequence.Will this work or else we have to configure another registers.

Hi,I have an ST25-ANT and I'm trying to make it work on a Nucleo F070RB. When I send the I2C Start there is no problem the device is recognized but then I try to send the MSB of the address and a NACK appears, I don't understand why the ST25DV takes the start condition but nut the register address I'm trying to read . Here is my I2C configuration :And my read function :Any help is appreciated, thanks !

I am trying to learn the in and outs of the STM32 Nucleo. I made my own .h and .c files to control an LCD screen atteched to my nucleo. However in these files I am trying to use HAL_UART_Transmit to write to the screen. I included the HAL.h file but the uart1 instance is declared in the main.c file. Is there a way other than passing the instance to every function I'm calling to use uart1 instance?An example of what I am trying to do is included in a code snippet below.void Clear_Screen() { HAL_UART_Transmit(&huart1, clear_screen, sizeof(clear_screen), Timeout); }I get the error: "'huart1' undeclared (first use in this function)".Thank you

Hello,I am attempting to integrate the X-CUBE-NFC5 package with an existing project using a STM32F469II MCU and IAR. I have imported and setup the directories exactly as the example project , excluding the application files; however, I am receiving a significant amount of errors and I am at a loss on how to resolve the issues. I was able to successfully build the example project provided with the package for the STM32F401RE-Nucleo board.The main issue is with the rfalIsoDepInfo struct and the rfalBitRate enum in "rfal_isoDep.h"/*! RFAL Bit rates */ typedef enum { RFAL_BR_106 = 0, /*!< Bit Rate 106 kbit/s (fc/128) */ RFAL_BR_212 = 1, /*!< Bit Rate 212 kbit/s (fc/64) */ RFAL_BR_424 = 2, /*!< Bit Rate 424 kbit/s (fc/32) */ RFAL_BR_848 = 3, /*!< Bit Rate 848 kbit/s (fc/16) */ RFAL_BR_1695 = 4, /*!< Bit Rate 1695 kbit/s (fc/8) */ RFAL_BR_3390 = 5, /*!< Bit Rate 3390 kbit/s (fc/4) */ RFAL_BR_6780 = 6, /*!< Bit Rate 6780 kbit/s (fc/2) */ RFAL_BR_52p97 = 0xEB, /*!&

Hi Everyone.Page 524, section 18.4.16 ADC timing of the STM32L476 Ref manual states.The elapsed time between the start of a conversion and the end of conversion is the sum ofthe configured sampling time plus the successive approximation time depending on data resolution:TCONV= TSMPL + TSAR = [ 2.5 |min + 12.5 |12bit ] x TADC_CLKTCONV = TSMPL + TSAR = 31.25 ns |min + 156.25 ns |12bit = 187.5 ns (for FADC_CLK = 80 MHz)This is almost exactly the same as, page 217 section, 11.5 Channel-wise programmable sampling time of the STM32F411 Ref manual.The ADC samples the input voltage for a number of ADCCLK cycles that can be modifiedusing the SMP[2:0] bits in the ADC_SMPR1 and ADC_SMPR2 registers. Each channel canbe sampled with a different sampling time. The total conversion time is calculated as follows:Tconv = Sampling time + 12 cyclesExample:With ADCCLK = 30 MHz and sampling time = 3 cycles:Tconv = 3 + 12 = 15 cycles = 0.5 μs with APB2 at 60 MHzHeres my problem. When I set up and run the “AD

Still learning H7 so apologize for a silly question.I want to use all Dx RAM parts on a single core STM32H743: D1, D2, D3.Now, in system_stm32h7xx.c , SystemInit there's following code:#if defined (DATA_IN_D2_SRAM) /* in case of initialized data in D2 SRAM , enable the D2 SRAM clock */ RCC->AHB2ENR |= (RCC_AHB2ENR_D2SRAM1EN | RCC_AHB2ENR_D2SRAM2EN | RCC_AHB2ENR_D2SRAM3EN); #endif /* DATA_IN_D2_SRAM */  RM0433 says about RCC_AHB2ENR_D2SRAM1EN "When set, this bit indicates that SRAM1 is allocated bu the CPU", and same about SRAM2EN and SRAM3EN. But wait, SRAM1 (does it mean D1_SRAM aka AXI_SRAM?) already is accessible by the CPU? And, if I have initialized data in D2 SRAM, is it too late to enable it, because initialization of data is in the .s startup file, before SystemInit is called?By testing it looks like D2 and D3 RAM can be read and written by the CPU even if RCC->AHB2ENR is 0. The question is, do I need to uncomment these lines in SystemInit? Are they actually inte

Hello,I have some preprocessors defined in my code and they're NOT greyed outThe problem is, the debugger is not accessing themEvery function under the definition is accessed OK.But if the #if condition is inside the function, the debugger ignores that codeI tried cleaning the project and rebuilding the index but the problem is still thereIf it's a function, it's OKIf it's a code inside a function, it's not ok

Could it only work with .out files? If so, how can I generate a .out file in CubeIDE?

I am using the RTC of the STM32F745 with 32.768kHz LSE.Principially, the RTC work correct on several PCBs.But there is one PCB where the RTC goes approx. 7 Min too slow in one hour.But if the unit is powered of and the RTC works with VBat for a while, it goes correct, if I control it after power on again.Has someone a clue, where to search the failure?

I'd like to connect one USB port to the RTOS, running on the Cortex-M4. According CubeMX this is not possible (no square availble to tick). Is this really not possible?According the datasheet (DS12505 Rev3, page 19, 'Block Diagram'):USBH is connected to AXIM bus, but the corresponding arrow is blue (= AHB ).The USB OTG I can not find there.According same datasheet (page 36, 'Bus Matirx'):USBH is connected to AXIMUSBO is connected to MLAHBThis is not clear to me.Denise

Posted on May 06, 2017 at 18:39Hello fellow Stm32 explorersI've searched for ethernet / TCP/IP examples for the stm32F746G discovery board but have found none.This seems weird since this board includes a PHY and a RJ-45 connector.There is a good chance that I've just walk right passed were they are located.I am working with the cube (this is my third stm32 discovery board) so i would prefer examples that are compatible with it (meanning examples that use HAL).I am mainly looking for examples that use Lw IP and that don't include Free RTOS but if the only examples include it ,I will work with it.I use IAR (32K max so limited for ethernet applications) and SW4STM32 (AC6's version of eclipse for stm32) so i would prefer IAR /GCC compatible examples.I've seen some people adapt examples for other discovery boards , if there aren't any examples for this board are there any examples that could be slightly modified to work on my board ?At this point im trying to learn TCP/IP on STM32's if the

Hi,In order to compile c-project directly on STM32MP157C-DK2 I've installed GCC 8.2.0 on the board but cannot manage installing libc6-dev library (or any other suitable one).Could you please help me to figure out the proper way how to do?For now I'm getting the following message when trying to do via apt-get.Package libc6-dev is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another source.Kind regards,Alexander Iotko
