Hi
I have a custom board with STM32F799 and USB host device for read a data file from flash Key.
The development software is STM32CUBEIDE V1.13.0
The firmware include TouchGFX with FREETOS V1 for manage a graphix display.
I configured USB_Host for Mass storage Host Class and include FATFS for USB DISK
In the FreeTOS I allocate the Task for USB with 2048 stack size priority Low default dynamic.
The start of task initialize MX_USB_HOST_Init(); ,it detect the USB device and in usb_host.c start Mount of USB device.
The problem is when active f_mount(&USBHFatFS, USBHPath, 1); the execution end with HardFault_Handler.
The Fault Analizer indicate Bus , memory management or usage fault (forced) / precise data access violation (PRECISERR) 0xa00ef2d4
I have another firmware without FREETOS thar read flash kay and run fine on the same board.
Someone have idea where is the problem?
Another question About USH_HOST
STM32CubeIDE auto generate the library wen istance device but the version of USB_HOST is 1.0 and there is an error in usbh_ctlreg.c line 561, I shall replace any time the row.
Is There a way to update the library in STM32CubeIDE?
Thank
