Hello,we have a custom board based on STM32MP151C. On our SPI is the Ethernet Switch KSZ8794. How should I proceed to enable the ethernet in the U-Boot? I have already configured the etherne0 node (according to the ST documentation). Should I add the node to the spi node?

We are using the latest STM32CubeIDE (1.4.0) and are trying to develop applications for linux user space on our STM32MP157 board. Our goal is to use the cross compiler toolchain for developing and debugging with the IDE.When we create a new project, it seems the IDE doesn't create any ready to compile main.cpp files for the A7 processor like for the M4. See this screenshot: For the M4, the project compiles with the template main.c just fine. But for the A7, nothing is there.So my question is, is there any documentation on how to develop linux user space application with the STM32CubeIDE for the A7?Thank you.Best regards,Kevin

Hello,I cannot use correctly TouchGFX Designer. When I use "run Target", when arriving at the step of stmCubeProgrammer, I have this issue :... ------------------------------------------------------------------- STM32CubeProgrammer v2.6.0 ------------------------------------------------------------------- Error: External loader c:\program cannot be loaded.

Does the ADC need to be initialized in a special way for the USBPD stack to work properly?I am trying to implement PD on a STM32G431 and the USBPD stack doesn't seem to work. If a powersource is connected, the CAD state changes to ATTACHED but then it immediately changes to DETACHED and waits for the VBUS voltage to drop to zero, which doesn't happen because the source is still attached and supplies the standard 5V.The stack is resetting right after the attached state.

Hi,I am working on Nucleo STM32H743ZII am using a 64byte size custom usb hid when I send my data frames i get an offset of 6 zeros as shown here :Any ideas where it comes from ?Regards,Gabriel

Hi,I started from scratch and successfully created STM3232H7B3I-DK project as in Workshop2020.Now i added a project library, it compiles and produces .a file but i have this message:libModuleA.a: file not recognized: File format not recognized.I suppose I have to setup the correct toolchain but i do not know how.The current toolchain is Cross GCC CDT internal builder.Many thanks if someone can help.Regards

I want to know the role of the m4_***(for example m4_adc, m4_timers1) node in Cortex-A7 Device tree.​When I generate device tree from CubeMX, the m4_*** node are described even if that peripherals are used only on Cortex-M4 FW.​Do I need to set status = "okay" in Cortex-A7 device tree even if ​that peripherals are used only on Cortex-M4 FW?for example, When I use timer6 only on Cortex-M4 FW, Do I need to describe that status = "okay" in m4_timers6 node in device tree?Best regards,H.

I created a new project in STM32CubeIde (STM32F401, USB Host MSC). I haven't added a single line of my code yet. When I try to compile the project, the error appears:../Middlewares/Third_Party/FatFs/src/option/../ff.h:29:10: fatal error: ffconf.h: No such file or directorySuch errors appear for almost every line of source code starting with "#include".I've seen similar threads on this forum before, but it's been a few months since then. STM32CubeIde menu structure has changed and the old advice no longer applies. I am asking for help in dealing with this error.

How can I disable breakpoints for release builds? If I accidentally forget a breakpoint on, and it gets hit in the release build, then the program just freezes (including halting the watchdog timer!) - what am I missing?

The size of "heap" in my project up to 70+KB in RAM.What are the factors that can affect its size？void touchgfx_init() { Bitmap::registerBitmapDatabase(BitmapDatabase::getInstance(), BitmapDatabase::getInstanceSize()); TypedText::registerTexts(&texts); Texts::setLanguage(0);   FontManager::setFontProvider(&fontProvider);   FrontendHeap& heap = FrontendHeap::getInstance();// this is too big (void)heap; // we need to obtain the reference above to initialize the frontend heap.   hal.initialize(); }

Hello, I use for STM32 (1.8V VDD) SPI communication with an slave temperature Sensor (3.5V basic voltage, detects high at 0,7*3,5V)SCLK =PC10SDO = PC11SDI= PC12CS = PC13For that reason I want to use an external 3.5V Pullup. But I'm not sure if this is OK for pinsPC10/PC11/PC12/PC13. Can anybody tell me if this is OK?And where I can find these information in datasheet? I already looked in the AN4899 Application note, but coulkdn't find which pins are 5V tolerant. In special if PC10/11/12/13 are 5V tolerant.Best regardsFabian

We are using STEVAL-SPIN3204 .While we testing the evaluation board,when we unplug the USB cable we are missing 12 volt @ VREG12,that is pin number 6 of STSPIN32F04B.Also the motor turned of.Also when we plug the USB cable 12 Volt coming back & Motor also start running.We dont understand why this happening.Can Anybody help to sortout this problem because we already designed a board using this refrence design.And while we tested we are not getting 12 Volt.

I used TouchGFX generator 4.15.0 to create a simple project (from GUI Template) on STM32F746 Discovery board, inside TouchGFX generator, "Run Simulator", "Run on Target" and "Generate Code" all are working correctly. However, when I tried to open the generated project using Keil MDK ARM Toolchain, it cannot be compiled. I compared files between the KEIL compile error message and Touchgfx Generator "Run Target" log, there are some bugs for the "Generate Code" for the toolchain Keil MDK.Some error messages from Keil MDK: "no source": Error: #5: cannot open source input file "../touchgfx/generated/fonts/src/font_verdana_10_4bpp_0.cpp": No such file or directory../touchgfx/generated/fonts/src/font_verdana_10_4bpp_0.cpp: 0 warnings, 1 errorcompiling Font_verdana_20_4bpp_0.cpp..."no source": Error: #5: cannot open source input file "../touchgfx/generated/fonts/src/font_verdana_20_4bpp_0.cpp": No such file or directory../touchgfx/generated/fonts/src/font_verdana_20_4bpp_0.cpp: 0 war

Hello ! I'm trying to communicate with a ADC : AD7276. With my MCU STM32H745To get the values from the ADC, I set the CS in low state and CLK 16 times. However, the HAL_SPI_Receive_DMA method does not activate the clock on the SPI.What are the parameters to activate the clock with this method?I tried with the HAL_SPI_TransmitReceive_DMA method. But the first byte is missing ( while the byte in TX is transmited ).I am in fullduplex and DMA TX/RX 8-ByteDataSize.Thanks You :)

Our project compiled and linked with no issues when set to HW floating point support. (i.e. The Properties -> C/C ++ Build -> Settings -< Tool Settings -> MCU Settings -> Floating-point ABI is set to "Hardware implementation ...".). However, some math calculations were (very) incorrect when I ran the program. I switched from "Hardware implementation ..." to "Mix HW/SW implementation..." as this worked before we upgraded all our STMicro software (i.e. libraries and tools). But now I see these errors when I try to compile the project:c:\st\stm32cubeide_1.3.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.win32_1.5.0.202011040924\tools\arm-none-eabi\bin\ld.exe: error: ../Middlewares/ST/STM32_MotionEC_Library/Lib\MotionEC_CM4F_wc32_ot_hard.a(motion_ec.o) uses VFP register arguments, LynQ Host.elf does not c:\st\stm32cubeide_1.3.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.7-2018-q2-update.

I'm getting started with the CAN controller on the STM32F105. One of the first issues I'm running into is that the HAL_CAN_Init() function returns an error. It seems to time out while waiting for CAN_MSR_SLAK to be cleared. Where can I find more information about this?Note:I have connected a CAN transceiver to the corresponding ports but there is no traffic on the bus yet. CAN RX is pulled high at 3.3 V.Putting the CAN controller into loopback mode makes no difference

I am implementing a custom bootloader for STM32F767 controller. Bootloader and application are in different sectors and on an update bootloader erases the application's sector and writes a new one. This works well, but sometimes the bootloader fails to clear the application's sector properly. Further attempts to clear it keep on failing. I can manually clear that sector with STVP and bootloader is then able to flash a new update there just fine.Any help is appreciated. Thanksif(HAL_FLASH_Unlock() != HAL_OK) return FALSE; FLASH_EraseInitTypeDef flashErase = { .TypeErase = FLASH_TYPEERASE_SECTORS, .Sector = FLASH_SECTOR_5, .NbSectors = 1, .VoltageRange = FLASH_VOLTAGE_RANGE_4 }; HAL_FLASHEx_Erase_IT(&flashErase);

Hi,We're currently using the SWO viewer in the old ST-Link Utility in Windows.However, this is a bit inconvenient for us because our main development is in Linux. Is SWO support planned for STM32CubeProgrammer? Even just STM32Programmer_CLI SWO support would be much appreciated.

hello, I use the component in a board to control gas solenoid valves in a cooking plane.I need to know for the regulations if in case of any fault or component breakage I always have a low or high impedance output value so as not to always excite the solenoid valveThat is to have a short between a VCC and OUT? or not?

Hello,I have a STM32WB35Cx MCU that has 256 K of flash according to the datasheet, in my STM32CubeIDE in STM32WB35CCUXA_FLASH.ld FLASH is given 128K of LENGTH. I changed this to 256K on my board without any noticable issues.
