I am tring to rebuild kenel for STM32MP157C-DK2 using below url. ​https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157C-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-A7/Modify,_rebuild_and_reload_the_Linux%C2%AE_kernelAfter I did 5.4 but it does not work and stop to this point ( root device /dev/mmcblk0p6...).Let me know how to can rebuild kernel for working.

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?

What's the MSL（Moisture sensitive level) of STM32F031K6U7, thanks.

In my application I am working with navigation data and would like to visualize coordinates in 2D, is there a way to do this yet?

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

Hello,I have followed this link: https://wiki.st.com/stm32mpu/wiki/X-LINUX-AI-CV_OpenSTLinux_expansion_package and successfully flashed STM32MP157c-dk2 device with AI OpenCV image.Now, I am trying to install python package scipy on the device. But it throws error that "unable to execute arm-openstlinux_wetson-linux-gnueabi-gcc: No such file or directory" and "error: command arm-openstlinux_wetson-linux-gnueabi-gcc failed with exit status 1"Could you please guide me? How can I install a python package on a device once the device is booted with AI OpenCV package.Thanking you,Saurabh

Hi, I'm building a program which has a part that is similar to the "Flex Button Example".In my case I've got a problem with Unicode. My program works the same as the image above. When I reach to number 24, 26, 28, 29, this is what it shows:This is my code:touchgfx::TextAreaWithOneWildcard texto; touchgfx::Unicode::UnicodeChar* memoria; int tama;   IP_AdressView::IP_AdressView() {   }   void IP_AdressView::adress1_button_pressed() { adress1_button.setBoxWithBorderColors(touchgfx::Color::getColorFrom24BitRGB(169, 172, 173), touchgfx::Color::getColorFrom24BitRGB(169, 172, 173), touchgfx::Color::getColorFrom24BitRGB(0, 0, 0), touchgfx::Color::getColorFrom24BitRGB(0, 0, 0)); texto = adress1; memoria = adress1Buffer; tama = ADRESS1_SIZE; buttonUppressed(); buttonDownpressed(); }   void IP_AdressView::buttonUppressed() { int tmpVal = Unicode::atoi(texto.getWildcard()); if (tmpVal >= 0) { tmpVal++; Unicode::snprintf(memoria, tama, "%d", tmpVal); texto.invalid

Hi everyone,I was wondering if it is possible to supply my VL53L0X with a 3V3 voltage?According to the datasheet, the 3V3 respects the recommanded operating condition.But when I look for example board from ST or other vendors, there is always a converter from 3V3 to 2V8. So I am a little bit confuse.Moreover, the note number (4) on the previous screenshot indicates that there is some API mode to set if the module works with 1V8 or 2V8. Sadly I did not find any related subject in the API User manual.Thanks in advance for your help.Regards,Alain.

Hello all,I have a STM32MP157C-DK2, and I want to use the minimal st-image-core.I have been able to use/build "st-image-weston", and when its starts, I can see my board on the local network, ifconfig says me eth0 has an ip address and I can ssh it.When I build "st-image-core", and successfully boot the board, I can't see it on lan. ifconfig doesnt show eth0.Can someone tell me why?command used:DISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.shbitbake st-image-westonDISTRO=openstlinux-weston MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.shbitbake st-image-core

I was planning to design a hand held uhf rfid reader using this ic. Is it possible to design one using this ic? if yes how to design the antenna for this reader.? What are the challenges in designing an rfid reader. Please help.

I'm running a ST25RU3993-EVAL with firmware version V2.0.0.0 STUHFL. Under "Reader Settings" in tab "Settings" under "EU Profile", within the TX-Options, there is a Selection-Field "Internal/External PA", which by default is set to external PA.When I try to set this to internal PA, I do get an error message "TX setting failed".Has anyone an idea, if this feature is possibly disabled by firmware, or even not yet implemented?

Please can any one help me,,,,its important for me...my project is pending due to this problem.Thanks in advanced.

Hello,I'm a student that is currently developing a firmware for a custom board with the STM32WB55CE-MC. I want to communicate with the MC over BT. I have tested my software on the Nucleo-Board where it works fine. When i try the firmware on my custom board, the microcontroller can not be seen in the BLE-Sensor app. While debugging the software, I realized, the MC never leaves the idle-State. I am using STM32CubeIDE for software developement.Has anybody experienced similar problems? Do I need to upload firmware to the RF-Core before I can use the BT-Feature? I have not done this up to now but I also have not done this with the Nucleo board. Thanks in advance for all your answers and kind regards,Florian P

Do you plan to add support for parsing static variables declared in functions?You already need to parse DWARF, maybe add location resolution for this type of variables also.You do it in STM32CubeIDE:We do it externally using pyelftools.Yes, there is a lot of assumptions in our script (compression, dwarf format,...), but it works in our use case.Kind regards,ZigaCode:Dwarf parsing useing pyelftools (modified example of https://github.com/eliben/pyelftools/blob/master/examples/dwarf_die_tree.py) to output also all DIE properties"current_" is on location:DW_AT_location = [3, 44, 1, 0, 32] DW_OP_addr = 0x03, next bytes are in little endian0x2000012C

why does cubemx V5.5 remove STemwin and TouchGFX part, will it move back? how can I use this part conveniently?

Hi,why it's not possible to copy all neccessary library files to my generated project for CubeIDE?When I choose EWARM, then this is possible...Thanks a lot,Ben
