[ECOS] memory layouts

[ECOS] memory layouts

[danish iftikhar]

Hi

  going through the eCos repository , i am trying to figure out how to 
change the memory layout ( linker script fragments) for porting it to other 
platforms . in the include/pkgconf directory , i found that there are 
specifically .h , .ldi & .mlt files .  But .h & .ldi are supposed to be 
generatede ones .
I am not able to figure out , how and from where are they generated.
If i have to make my own linker script fragment , then where should i make 
my scripts or can i edit any of these files dirctly to map my platforms 
memory layout , if so which files .
where can i get a good tutorial specifying different sections used in these 
files such as "fini" , "fixup" etc..

regards
danish.

Please see these:

+ to generate the files, you need to run the configuration tool under
WinDOS. If you don't have access to that, just change the .h and .ldi
files by hand (ignore the .mlt file).

The sections are defined by the linker, try 'XXX-elf-ld --verbose'.
But if you are just adding a new platform, the architecture/variant
already defines the necessary sections (see the .ld file)
