Posted on August 19, 2017 at 14:16Hi,
I am facing issue with USB HOST in STM32F407VG Discovery board .
I want to create new folder and text file in 32GB OTG pendirve which is connected to STM32F407 Discovery board.
USB Configuration:
1. USB HOST
2. Mass Storage device.
3. FATFS : USB Disk
Code is generated using STM32CubeMX
In while(1) after USB detection , we called following API
1 . disk_initalize(0)-------- success
2. f_mount (&fatfs, '0:', 0) --------------success
above two api gives status ok result.
but when we try to create file using f_open(&file, 'hi.txt',,, FA_CREATE_ALWAS|) we get Disk error.
#mass-storage-device #stm32f4 #usb-host #f_open
