Hello, ST expert CubeMX generated software framework is used for our STM32U595VJT6 based hardware design. It works well but for the low start up time. It takes almost 1 second between 3.3V is stable and the flag GPIO turns high in MX_GPIO_Init. Is th...
Hello, ST experts STM32U595VJT6 is used on our own HW design. There is external SD3.0 compliant level translator NVT4857UK to help to work on UHSI mode. Everything is fine when SDIO clock sets as 96MHz or lower. But when the SDIO clock is higher than...
Hello ST experts I found the same problem as previous post  https://community.st.com/t5/stm32-mcus-embedded-software/stm32f072xb-gpio-issue-usb-pins-do-not-work-as-gpio/m-p/151104#M8715  But for stm32u595, I can not find the similar register USB_CNTR...
Hello, ST experts STM32F417 is used on custom hardware design. And everything is OK except SD card. At first SD card works well. f_write takes about several milliseconds. But when the free space of SD card(San Disk Ultra 64GB) is less then e.g. 10GB,...
Hello, ST expert​From the picture below, it showes that 5V tolerent GPIO connect to VDD_FT through a protection diode. But what is detailed difference between VDD_FT and VDD?​ BRYang​
