STM32L4 fails to boot after the battery ran out
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...
NTP Client OR NetworkInterface.c file for STM32L475VG on DISCO-L475VG-IOT01A
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...

STM32F105 USB problem
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...
