Why did my STM32H747I-DISCO flash memory got increased from 2mb to 6 mb? And B-cams-omv not getting detected

Stm32h747i discovery kit comes with an 2mb flash memory, I am trying to run an example project which is pasta detection based on this blog 

AI:How_to_use_transfer_learning_to_perform_image_classification_on_STM32

but after some how after flashing the code, camera input is not going to the board and it is showing 6 mb available flash memory. I dont know how it got increased all of a sudden.  And B-cams-omv not getting detected, even usb web cam example not working from FP-AI-VISION1 pack example

Not sure where you are seeing this.

STM32 Cube Programmer?

The board has some external QSPI memory, doesn't it?​

It is seen an as an mounted device, that image is from my pc. And about QSPI memory in the data sheet it was like

Quad-SPI Flash memory Two 512-Mbit Quad-SPI Flash memory devices (MT25QL512ABB8ESF-0SIT from MICRON) are fitted on STM32H747I-DISCO in positions U3 and U14, making possible the evaluation of the STM32H747XIH6 Quad-SPI interface.
