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...
