I configured 2 file storage devices on my STM32H745I-DISCO board.USB_OTG_FS and SDMMC1 (for built in eMMC).Both devices initialize properly without errors.The USB host detects the device, it correctly identifies it as media storage class device.It en...
Board: STM32H745I-DISCO.Component: USB_OTG_FS.Mode: Host_OnlyWhen the Activate_VBUS is set to "VBUS sensing", the USB port is not powered and it doesn't work. What's important, the pin used for VBUS (PA9) cannot be selected in USB_HOST as Drive_VBUS_...
Hello everyone, when I was watching the stm32f429 routine, there was an example of upgrading the user program with the U disk. It was mentioned that the configuration of the user program needs to change the contents of the [toolchain linker file]. Wh...
We have some products in the field that have historically used DFUseDemo together with the Windows driver "STTub30.sys". That worked well as it is quite a concise tool that is easy to install.ST have replaced that with STM32CubeProgrammer which is m...
I made a High Speed USB DEVICE using USB PHY with STM32F207.When delivering data to the HOST, there are small-sized data (less than 512bytes) and large-sized data (more than 1Mbytes).At this time, I want to transfer small-sized data without using D...
