Solved

Hello!I need to debug multiple tasks but when I try to enable FreeRTOS support (Debug configurations/Debug/Enable RTOS proxy/FreeRTOS+ARM_CM7) I can't connect to my MCU (STM32H743) with a message box saying "Could not verify ST device" while console says "Failed reading: xList.pxNext Update threads. Failed collecting threads. Lost connection to GDB Client Proxy stopped."I was able to connect once with OpenOCD but then it fails also with errors in console: "OpenOCD Info : New GDB Connection: 1, Target STM32H743IITx.cm7, state: halted Error: Failed to read memory at 0x79280480 Warn : negative acknowledgment, but no packet pending"How it is possible to debug multiple tasks?Regular firmware download and debug without FreeRTOS proxy works perfectly.STM32CubeIDE Version: 1.9.0 Build: 12015_20220302_0855 (UTC)

Hello,I define following constant string, indicating the program version.static const char version_s[] __attribute__((used)) = "V.10";This string isn't used in other part of code, but is only defined with the purpose to put in the binary file, a string easy to find, and to make the CRC over the code, depending from the program version.However, I see that the version string is not included in the binary file, and consequently CRC doesn't depend on it.Where is the mistake?Thank you,Carlo.

These are the steps in chronological order to be able to build the files for a custom board. This seems very convoluted and easily confusing. I this process correct  ? The issues normally are not found with the STM board because all the pre-build files are already in the fip  and other source folders, but for a custom board they are not, hence the issues.Build sequence:=================* Install the SDK* SDK source set to the arm toolchain* Extracted all the sources and applied the patches* Copied the device tree files from CubeMX to the respective folders.* Updated the makefiles.sdk with the the new board name.* Added the device tree file name to the makefiles in fdts and dts sub-folders (TF-A / u-boot)* Set the $FIP_DEPLOYDIR_FIP' and $FIP_DEPLOYDIR_ROOT* Deleted all the custom board files under $FIP_DEPLOYDIR_ROOT that were built before during trial (& error)Steps and issues encountered in chronological order:1. Build u-bootmake -f $PWD/../Makefile.sdk all UBOOT_CONFIG

I am playing with the TIM_InputCapture example (calculates frequency of external pulse) for the NUCLEO-H563ZI dev board. The example works OK except:Frequency is not updated for no edges (signal generator off)Minimum frequency is about 3KHz. I need to measure 0 - 2KHzThere should be a way to trigger the latching of the count reg in SW rather than the timer. The pulse frequency is low enough that I can look at the pulse count in non-ISR code. How do I (a) trigger the latching of the count reg, and (b) disable the timer event?

Hi, I come across debug mode using stm32 IDE and i would like to know whats the difference between serial wire and Trace Asynchonous sw? I know both are use when debuging the Nucleo144 board. And if u wana use a IC chip which mode should i use? JTAG mode? JTAG with Syno ? i m reading AN4989 and its not talking much about this. Can anyone kindly advise?

I am trying to get a clear understanding of the memory map for this board. I want to the know the address locations of the SDRAM and both QSPI flash devices. The board user manual says SDRAM is in Bank 1, which RM0399 says is 0xC000000, but when examples show that 0xD0000000 is the location of the SDRAM. When I run a variation of an example to access the LCD 0XD000 0000 is the correct location as 0xC000 0000 hit a hardware fault. Is there an updated table or documentation stating the full memory map for this board? 

Hi,I can't get a simple ST7789 screen working I have tried using this library:- https://github.com/Floyd-Fish/ST7789-STM32 double checked all the connections (including external 8MHZ crystal) and all seems to be fine, I have tried various different settings with the SPI and DMA none of which work. Just wondered if anyone here has had a working program? I am using a simple Nucleo STM32F303K8 MCU. All I get is blank screen.

Hello Community,Is it possible to initialize and start the Real Time Clock (RTC) of the STM32U585 at the same time as the firmware and Option Bytes are installed into the MCU with STM32CubeProgrammer SFI process?

Hi Team,Currently we are trying to prove out the HSM in SPC584B70ES hardware.HSM related information is not available in User manual and data sheet.We need SPC584Bx Microcontroller security reference manual document to refer HSM information.Could you please provide asap. Thanks...

I have multiple LSM6DS3 (with SH SMD markings) and all of them show the same strange behavior.The chip is soldered to a breakout board that is set up on a breadboard. And is connected to the MCU breakout with 20 cm jumper wire.1. When I read a register, they return the registers address as the register value. The exceptions are the ID register, which is correctly returned as 0x69 and the Data registers that contain the acceleration and gyro data.2. Reconfiguration (for example the resolution) will take effect only after a power cycle and another write. I tested it multiple times while changing the SPI wire lengths to make sure it's not some kind of glitch from bad wiring.3. The Gyros Z Axis is always outputting zero.4. Configuring the secondary I2C for reading a slave magnetometer does not work, the I2C does not show any activity on the lines. I implemented it according to Application Note AN4650.The sensor values that are put out are correct (except gyro-Z), and change as expected whe

I am using the custom board based on B-G431B-ESC1 and the same software, but i am struggling to go beyond 10NM torque i am really not able to understand the root cause of the issue. One observation is the Valpha and VBeta is going beyond 28000. Is that the reason? Please help. What are the other parameters i have to look for?

Hi there, I'm developing a board that features the ST25R3911B chip. At the moment I managed to integrate the module in order to read and write simple NTAGs (t2t), with plain text (both on demoboard X-NUCLEO-NFC05A1 and my custom board).The next step is to interface with higher-level devices (smartphones) and I need to read and write custom APDUs based on standard ISO7816. I'm not familiar with that (and generally with NFC protocols). Does somebody know how I can achieve that? Thank you so much!

 I work on project from a few daysI want to connect two audio codec with STM32H745to receive data from first one and then processes it , and then transmit it to the second one and versus versa.how to implement a part of code to organize exchange data in two direction TX and RX.best regards

Hi everyone,I've just migred my project from st25r95 to st25r2916 NFC chip. Finally I could reach a good point where seem to be all working again.But I have one issue with rfalNfcvPollerReadMultipleBlocks() function.Firstly, I want to describe you the sequence I do to execute the function I said above:1. I do an Inventory to discover the tag UID2. I use rfalNfcvPollerGetSystemInformation() to retrieve the information about the TAG3. Finally, I use rfalNfcvPollerReadMultipleBlocks(RFAL_NFCV_REQ_FLAG_DEFAULT | RFAL_NFCV_REQ_FLAG_SELECT, NULL, 0, 2-1, &data[0], (2 * 4+ 1), 7);NOTE:number of blocks = 2block size = 4data is a buffer I am using a non-addressed mode, but in addressed mode the behavior is the sameWith this configuration, I get CRC_ERR (0x15) as a return code.I don't understand what it means. Could you kindly explain it to me, please? What could cause this error?Thank you very much.Enric Puigvert

Hi,I just found an error in the data sheet and wanted to let you guys know. Don´t know who else to contact.Kind regardsRené

Dear All, I have followed the instruction as per Intro to Embedded Linux Part 2 - Yocto Project.The compilation for layer kirkstone. When i run the command "bitbake core-image-minimal" it give error after 4 hours of work.The error is pasted below./home/mypc/Projects/yocto/build-mp1/tmp/work/stm32mp1-poky-linux-gnueabi/m4projects-stm32mp1/1.6.0-r0/git/Projects/STM32MP157C-EV1/Demonstrations/AI_Character_Recognition/Src/app_x-cube-ai.c:91:3: internal compiler error: Illegal instruction | 91 | if(imax >= 0 && max > 0.5F) | | ^~ | 0x1521b50 diagnostic_impl(rich_location*, diagnostic_metadata const*, int, char const*, __va_list_tag (*) [1], diagnostic_t) | ???:0 | 0x15227d6 internal_error(char const*, ...) | ???:0 | 0xb7838f crash_signal(int) | ???:0 | 0x1721239 __gmpn_tdiv_qr | ???:0 | 0x17036ed parsed_string_to_mpfr | ???:0 | 0x1704497 mpfr_strtofr | ???:0 | 0xae57ec real_from_string(real_value*, char const*) | ???:0 | 0xae61cb real_from_string3(real_value*, char c

The otherwise excellent STM32CubeMX tool has a bug in its Configuration Report output (reached via the File > Generate Report command). In the Peripherals and Middlewares Configuration section of the report, the left and right columns of the output are reversed or (more likely) line-wrapped.See attached screen shot for an example -- this continues for many pages.I could not find a better way to report this, so could the developer of this STM32CubeMX tool please to look into this issue, because it makes the report output very awkward to interpret.Note that the STM32CubeIDE suffers from the same problem; it probably uses the same report generator.Thanks in advance on behalf of all your customers.-- David Adams

Hello Community, Since the latest release, we faced issue with lost files and folder in Keil workspace after code regeneration. Temporary solution: Generate the code as usual Go under the MDK-ARM folder under the project repository and add an empty file named "project.uvmpw" The added folders and files in Keil will be kept when regenerating code. Permanente solution: A permanent solution will be implemented in a patch release (CubeMX 6.9.1) which will be released in the near future.  

Hi. I use STM32F767, Arduino Mega and Arduino Nano boards.  Arduino boards is a slave devices. Stm32 board is a master board. I communicate with Arduinos and STM via I2C. Information comes from Arduino cards. I can see the information in debug mode. I want to print this information (the information comes as char information) on the Nextion screen. I was able to create another project and print information on the nextion screen. But I couldn't do this.  I uploaded my codes. Can you check my code? What is wrong? Thank you for the answer

Hi. I tried to modify the demo that comes with the STM32U5A9J-DK.When I modified display orientation (Config->Display->Display orientation in TGFXD) I found that it's not handled correctly. In the "SVG" screen there's a couple of logos which should move around to show all the resizing and transforming capabilities of svg graphics.If orientation is changed they still move around but they leave a kind of "trail" and some other artifact.If I switch back orientation everything works properly.After applying the modifications, I just generated code by using TouchGFX Designer 4.22.0 and then compiled and loaded it with STMCubeIDE 1.13.1. I had no errors or warnings.Is it a bug?

I would like to ask your team some of questions regarding the STM32 module kit which comes with BLE- 5.3 or BLE5.4, I want to make a device which works on BLE-5.3 or 5.4. I want to establish an AudioLE call by using your microcontrollers, Can I use AudioLE with any STM controller, If yes then how can I and if not then shall I do to make it work?Will it work on full-duplex or half-duplex communication?Can a 2 ways communication be possible using a single STM or will I need 2 STM to have a communication? Or can I use multiple channels with a single STM for communication?Please answer these questions I have as soon as possible.Thanks
