I am running into an ECC error when writing to flash when the device is powering down - unfortunately this is a state I cannot control. In the NMI handler when the device boots up I read through the flash and an ECC error pops up and the NMI Handler ...
Hi, I sometimes get this error when starting a Debug on an F439ZIError in final launch sequence: Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK device.Reason: (5) Unknown MCU found on target. Unplugging and repluggi...
Hi, I am using G474RE nucleo board and I want to communicate between the UARTs available on the board (UART2,UART1 and UART3). Message is not transmitting complete in to UART1 from UART2 and same with UART3 from UART1
Dear team,We are currently in the process of designing a custom board centered around the STM32F103VET6 MCU. Unfortunately, we have been unable to locate a reference schematic that features this specific MCU. We kindly request the following informati...
Hi All,We are using MCU STM32F427ZIT7 for one for our products. We uses serial programming mode to program flash. Below is an interface with 10 pinNow we are using below MCU for another application.STM32F030C8T6TRFirst one is F4 version and later is...
Hello,I have an STM32l476G evaluation board. I've configured the CubeMX project to enable the RTC to be run from the 32KHz LSE crystal which should be X1 on the board. However, when putting an oscilloscope on the x1 pins, I do not see any oscillation...
Hello everyone! Recently, I started to use the CMSIS HAL to program my Nucleo-stm32l476 board, and currently, I am working on a project using the ADC1, for the data acquisition from an LM35 temperature sensor, and I have found some problems in the co...
The LED is not working anymore when debuging, can I recover the previous version of firmware?
I tried setting up Nucleo board, and every time I debug the code, it goes to HardFault_Handler(). How do I solve this?I assumed there could be a debugger issue and I tried all the firmware for ST Link. No luck. Can anyone help?
I recently purchased an L4R9 Discovery board with an MB1314 round LCD.Under STM32Cube_FW_I.4_V1.17.2 / Projects / 32L4R9Discovery / Examples / DSI / DSI_CmdMode_SingleBuffer, there is a reference to a 24bpp frame buffer. The comment cryptically state...
