Solved

I am following the instructions in the 'UM1718 User manual", section 10.9, "Switching to another MCU".In STM32CubeMX I opened a new project and chose the F303RETx MCU option. Then I imported a working .ioc file into STM32CubeMX that was originally set for the F303RCTx, then, as described in the instructions, did Try Import, which worked, then named the project, and clicked Generate Code, for the STM32CubeIDE, which worked, no errors reported.But, when I open the project in STM32CubeIDE, and try to compile, I get the error about missing files as follows:compilation terminated.make: *** [Drivers/STM32F3xx_HAL_Driver/Src/subdir.mk:81: Drivers/STM32F3xx_HAL_Driver/Src/stm32f3xx_hal.o] Error 1In file included from ../Drivers/STM32F3xx_HAL_Driver/Inc/stm32f3xx_hal.h:46:0,         from ../Drivers/STM32F3xx_HAL_Driver/Src/stm32f3xx_hal_adc_ex.c:55:../Inc/stm32f3xx_hal_conf.h:206:12: fatal error: stm32f3xx_hal_exti.h: No such file or directory &

Hi!I use M24LR64E supplied with 3V3 and communicating with PIC microcontroller.I am facing a big and urgent problem: I2C writes are working really fine according to manual specification until the memory is subjected to EMI. After that, any I2C write returns NACK.How can I work around?

I'm using STM32CubeMX 5.4.0. When I enable LTDC and DMA2 interrupts (for example) in the NVIC tab in NVIC Mode and Configuration, when I switch to the Code Generation tab there are no entries for either LTDc or DMA2D. See attached screenshots. What is preventing Code Generation ?

Hi,from Properties -> Paths and Symbols i added file path to 'Include Directories'. Then, i added my source file and my header file to 'my_libs' which i created under project_name -> Drivers.When i call a function from library i see 'undefined reference to (function_name)' error.How can i fix this? Best regads.

Can someone explain to me how I can do to be able to view all the settings? The cursor is on the edge and there are still too many settings to list that I can't see.Since they released version 5, CubeMX has become increasingly confusing and difficult to use ...

Has anyone had this problem and how did you fix it? I am having this problem on the nucleo board.

It does not work , it gets detected as unknown device,what am i missing , should i add something more to cube mx generated code. Thanks.

IDE and CubeProgrammer require the JRE to develop products and bring them to the market and OpenJDK is not an option. The question has been posted in several topics lately. The MP1 incudes Linux, is there a license impact to release products with ST provided boot, kernel and system images to the market ? Personally, until now managed to keep the Oracle JRE off any of the systems unti

CURRENT PRODUCT Our existing devices have a custom USB DFU bootloader starting at address 0x08000000. Our main application starts at 0x08008000, after 32Kb of space. I can jump from the main app to the bootloader with no issues (using a NVIC_Systemreset) and back from the bootloader to the main application. NEW FEATURE I need to extend the capability of the bootloader to include OTA, however, existing customers are not able to re-program the bootloader without special tools. So the bootloader code (0x08000000) portion MUST stay the same.ATTEMPTMy solution is to add the OTA portion at 0x08008000 (PROGRAM 1) and shift the main application up to 0x08010000 (PROGRAM 2). I made adjustments to each linker script and in the system_stm32l4xx.c to ensure the VTOR is 0x08008000 for PROGRAM 1 and 0x08010000 for PROGRAM 2. When I look at the memory map the SP seems correct with each address 0x08008000 and 0x08010000 having a value of 0x20010000.When I jump I use the following code block from DFU e

Hi, I am using an STM32L4 MCU and I need to make the COMPx_OUT acting as a retriggerable monostable output. ​I know I can use timers as blinking source for COMPx_OUT, but this would not help, and as far I understand, the only way to solve my problem via firmware would be, at each EXTI interrupt:​Set to VOH the GPIO outputStart a one shot timer for t secondsSet to VOL the GPIO once the timer has overflowed.​Am I missing something or is there any better automated firmware solution ? ​Thanks for any hint. Regards. s

Hello community, am writing here because I need support in designing an RFID-based system.At current stage I have settled on the ST25RU3993 IC as an RFID reader. However, I can't understand if and how an antenna should be connected to the IC.Can anybody guide me in the right direction?​Thank youM​

Hallo ,I am trying to debug an imported project from CubeMx, which is just the configuration of the STM32MP!57C-DK2 board, I built the solution in the system workbench and then connected to the board. on the Console I cannot see any IP Address for the board, so i used ifconfig, and i entered the eth0 ip address in the debug configuration, when i debug the solution, i end up with this error message(attached).I attached my debug configuration as well. I also tried port 3333 which got the same problemI tried to debug just the OPENAMP_TTY example, it cannot be compiled (Photo- OpenAMP)I wonder what is wrong?. Your help is very much appreciatedNote; Regarding the OpenAMP problem, I saw the answered question, i followed the answer but the problem still exists. Maybe there should be some sort of special ocd or gdb config?. I am not sure as am totally new to that boardThanks in Advance

Hello, I'm using the OpenAMP_TTY_echo example with some modification.if (VirtUart0RxMsg) { VirtUart0RxMsg = RESET;   while (data < 65535) { itoa(data, buf, 10); if(VIRT_UART_Transmit(&huart0, (uint8_t *)buf, 10) != VIRT_UART_OK){ Error_Handler(); } data ++; }   data = 0; }On Linux side I'm use write on ttyRPMSG0.But if I don't read, the log give me the message:rpmsg_tty virtio0.rpmsg-tty-channel.-1.0: No memory for tty_prepare_flip_stringI think that I'm understand the problem, but what can I do to prevent this problem?

Hi,I've generated a code using CubeMx 5.1.0On MCU STM32F103C8T (Blue pill)I want to controll PWM duty pulses thru DMA in Circular mode.I want to use circular buffer and on half transfer I want to update half of an array that I sent thru DMA to TIMer for PWM.I was able to setup TIM with PWM and DMA. Now PWM is generated according to my array of dutys. Now I want to update array content on half and full transfer bu I don't hnow how to setup callback on such event./* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2019 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under BSD 3-Clause license, * the "License"; You may not use this file except in compliance with the

Hello,I am running example "OpenAMP_TTY_echo" on the board "stm32mp157c-dk2"I have modified the code a little bit so that channel0 (uart0) doesn't have to wait for a massage from linux side and transmit message every half second. It is sending the messages on every half second without problem.But the problem is now uart1 is not working. I mean on linux side if I write "echo "Hello Virtual UART1" >/dev/ttyRPMSG1" , I can not receive any callback message from the console. This means channel 1 is not working because channel 0 is blocking it. Is it normal ? Why normal ?while (1) {   OPENAMP_check_for_message(); " " " " VIRT_UART_Transmit(&huart0, Data, size); HAL_Delay(500);   if (VirtUart1RxMsg) { VirtUart1RxMsg = RESET; VIRT_UART_Transmit(&huart1, VirtUart1ChannelBuffRx, VirtUart1ChannelRxSize); }   }

Hi,Im using the System Workbench and a strange behaviour occured to me.When a certain halting point is reached, Im not able to step to the next one. Pressing Resume brings me back to the very same halting point, stepping over aswell. And stepping into always brings me to the Ethernet Interrupt Handler.Is this by design or a bug?

I am trying to make UART printf work with STM32F746-DISCO board.I tried running printf successfully with a default clock (whatever it is--I am not sure).I was doing it without using STM32CubeMX code generator.Now I found the code generator to be useful, I tried using the SystemClock_Config() function it generated for my board, which increases the clock speed up to 200MHz from my understanding.However, when I increase the clock speed with the SystemClock_Config() function, my printf does not work.Specifically, by using a logic analyzer, I figured that the baud rate becomes too fast, around 359689 (when I set it to 115200).I am attaching my main code below -- it is mostly just a stripped-down version of what STM32CubeMX gave me.If I comment out SystemClock_Config() from the code, the printf works fine.Can anyone help me with what is happening?Thank you
