We had a sensor based on STM32L4 installed in the field for a few days. It worked fine until the battery died and the device turned off. The problem is the MCU could not boot up after connecting it back to power. After connecting via SWD, STLink indi...
I am trying to initialize the RTC on the STM32L475VG with the current network time, so I would like to use NTP. I am also using FreeRTOS. NTP uses UDP as a protocol and I would like to use FreeRTOS+TCP to connect to this socket. However, FreeRTOS+TCP...
I maked simple program with LWiP. After I got dinamyc address, I tried socket connection and call netconn_bind halted MCU.My code: for(;;) { if(OK_D == 0) { IP_A = gnetif.ip_addr.addr; if(IP_A == 0) { HAL_GPIO_WritePin(GPIOB, GPIO_P...
hi Im using stm32f105rb mcu to read files from usb using fatfs libraries and i am able to read upto 17 files simultaneously more than that will shoot a disk error. what will be the root cause and is it possible to read more then 50 files simultaneous...
Hello,I'm using a NUCLEO144 board. I've enabled FREERTOS and LWIP.I have:one thread in charge of endlessly sending (netconn_sendto) out a message to a distant host and sleeps for a second osDelay(1000) a second thread in charge of receiving data from...
I use a STM32F105. On the board there is a bootloader and I upload the firmware through USB (host, OTG_FS). Then I use the USB to extract a log file (.txt). The extraction of the log works only if the optimization of the code is 0. If I set optimizat...
Hello FolksI dont have access to boot pins to enter system memory to use st bootloader for flashing the stm32 micro. There is an option to jump from user code to bootloader code but I want to keep read protect level 1 in option bytes. So if I erase t...
We are using STM32L496RGT controller in our product, the controller flashing (Program uploading) doing through USB. Initially device flash properly, but after multiple time flashing device shows error i.e USB USB not recognized, or port is not detec...
Hello, I'm developing an application for the STM32F302R8 using the STM32IDE.What is happening that any pin I choose as external interrupt EXTI, when the pulse that is free from bouncing (I checked with the oscilloscope) the EXTI handler is called sev...
Hello,I'm using VCP to communicate with an STM32F303 device, which works well.However, when I plug a second device on the same computer, it fails to enumerate properly with the message 'This device cannot start. (Code 10)'.Is that a known issue?Is th...
