Need your urgent help for interfacing TFT to STM32F756 using SRAM.
We are currently using STM32756 Evaluation board having TFT on it. The example provided for the TFT uses onboard SDRAM. We wanted to use SRAM instead of SDRAM.
So we modified the example and initialised SRAM using BSP_SRAM_Init() ,
Also the address for frame buffer was redefined using "#define LCD_LAYER0_FRAME_BUFFER ((uint32_t)0x68000000)"
We were not able to see the output properly, the images on the screen are printed multiple times and with lot of flickering on screen.
The SRAM provided on the Eval board is 1M x 16 and the example provided works with SDRAM 8M x 32.
Then we tested SRAM read write function, it was working fine.
Is it because of 32bit or 16bit alignment issue.
What could be the reason.
pls reply asap.

Rohit M
