How can I write a linker script to tell the linker to place sections around a "hole" in my memory region?
Is it possible?
I define a memory region
/* 0x0 -> 0x4000 */
FLASH (rx) : ORIGIN = 0x0, LENGTH = 16K
Now I define an output section for my code
} > FLASH
Now I want to make sure that the linker never places?
anything inside of the area 0x2000 -> 0x3000. How could I express that?
I could for example define the memory as two regions (starting at 0x0 length 8K and 0x3000 length 4K) instead,
but then I would have to manually place code from different object files/sections into the two regions to fill it optimally (?).
Is there a way to make the linker take care of this for me?
NOTE: the above linker script is simplified for demonstration purposes
