TCP client error, TCP Port number reused -> STM32f417 + CubeMX + LWIP + RTOS + Netconn TCP client
Hi All, I have written simple TCP client using Netconn interface in LWIP on stm32f417 board. Client connects to LWIP server that is also on another stm32f417 board using Netconn api. After first succesfull TCP transmition, connection freezes, when co...
Resolved! FOTA in STM32L0
For an application, I need to implement FOTA through UART/USB for STM32L0 microcontroller. Are there any examples or firmware packages available for this?
Resolved! Error with timeouts constants in stm32f7xx_hal_sd.c in SD_SendSDStatus and SD_FindSCR cause indefinite hangs.
Both these functions contain the code:"if((HAL_GetTick() - tickstart) >= SDMMC_DATATIMEOUT)"However SDMMC_DATATIMEOUT is defined as 0xFFFFFFFF so the timeout is very long (49 days with a 1ms tick) and therefore never occurs.That upshot is that if the...

Hello, I am using the STM32L4 Micro-chip on a board I am using, and I can across a weird issue with the usb. When ever I was running iar and trying to open up the com port within another serial program, the serial program was unable to open the com p...
Resolved! stm32h723 lwip configuration problem
I wanted to replace my system that used to work with stm32f407VGT6 with STM32H723VET6 as it is cheaper.I designed a new pcb, followed the steps in the link below and created a project.https://community.st.com/s/article/How-to-create-project-for-STM32...
STM32F4 HAL RTC Library Output
It appears that if the output bit is set (RTC_CR_COE) it doesn't get cleared when the RTC is initialized.In the library code:HAL_StatusTypeDef HAL_RTC_Init(RTC_HandleTypeDef *hrtc){... else { /* Clear RTC_CR FMT, OSEL and POL Bits */ hrtc->Instan...

Hardfault_handler on __sfputs_r() when using Freertos and X-NUCLEO-IDW0xx1 wifi module.
Hello everyone,I am currently doing a project using a Nucleo STM32F401RE with CubeIDE software. I am trying to use the X-NUCLEO-IDW0xx1 wifi module and the X-NUCLEO-53L0A1 sensor module with FreeRTOS. For now I succeed to make X-NUCLEO-IDW0xx1 work a...
Is there a way to read which product part number is connected via DFU bootloader?
I'm looking for a way to detect which device part number (EX: STM32F765...) is connected via the USB DFU bootloader before programming the device (as a sanity check to make sure the file is appropriate/compatible). I can see the VID/PID/REV and Opti...
