Hi Pachu.

When I get the image through serial port, it get saved into SRAM, but not forever, since SRAM lost their data when it haven't power supply.

You could use FLASH for this, but I think this memory will not be enough fast to transfer the data from it to VGA controller, maybe you would need some code for pass the data from FLASH to SRAM first.

Also you could save in the FLASH more than one image, and then, copy only one to SRAM at a time to show it.

Here's the top level code, that I used for this.

Be advice I'm a very beginer in this, so the coding is not very academic, and poor. (but works).
