Getting OV7670 camera data in STM32F7 SRAM memory to computer

I have interfaced OV7670 camera to STM32F7 using DCMI DMA in snapshot mode. The OV7670 is configured to provide with QVGA resolution.image data in RGB565 format 
I am saving the data to the SRAM1 memory (starting from 0x2001 0000). 

I am not able to transfer the data from SRAM using USART since source memory location parameter of the HAL_UART_Transmit_DMA is limited to uint8_t (but the SRAM memory location address is uint32_t).

could anyone help me to understand
1. how i can get the data from the SRAM memory location to computer?
2. how the data received can be used to view it as image?

Thanks in advance for the help.

i am able to say that the data is getting saved in the SRAM memory location, because when i print the data in the memory location(pointer to the memory address) using printf (in hex format) i am able to view data after the frame capture is over.
