Compiler/RM48L730: linker script when using FEE API

Hi,

The equivalent GCC Linker to determine LOAD addresses is specified by the AT directive applied to a custom memory section. A crude example would be:

Code said:

MEMORY
{

RAM (rw) : ORIGIN = 0x0, LENGTH = 0x200
ROM (rx) : ORIGIN = 0x2000, LENGTH = 0x400

}

SECTIONS
{

.text : { ... } > ROM

(...)

.const_data : { ... } > RAM AT>ROM

}

This is discussed in some places around on the internet such as:

https://stackoverflow.com/questions/15912057/section-load-address-and-execution-address-in-linker-script 

GCC leaves to the user to define the symbols equivalent to LOAD_START, RUN_START and SIZE. They are evaluated using the linker arithmetic expressions. The example in the discussion above shows them defined as _data_start and _data_end together with the Location Counter (the '.' dot linker variable)

Additional details about the Location Counter can be found at:

Hope this helps,
