External Memory Stream IT

Hi,

I am usinfg SDK for camera and I would like to save and show my buffer in External RAM (SDRAM).

I defined my buffer like this : "static uint8_t video_buffer[(VIDEO_BUFFER_STRIDE * VIDEO_BUFFER_HEIGHT) * VIDEO_BUFFER_NUM] __attribute__ ((section("SDRAM")));"

But I have an Image Error (see below)

How I can set up board init.c to have a good image ?

Or , How I can set up the QSPI loader to copy and run  my program on external memory directly ?

Thanks for your reply.
