[ECOS] editing MLT files?

[ECOS] editing MLT files?

[Ben Wu]

I'm creating a new board based of one of the XScale dev boards. I need 
to modify the ECOS memory layout files, but there are nice big comments 
saying :

// This is a generated file - do not edit

Can I safely ignore that comment if I'm only using using command line 
tools? Is there a command line tool I should be using to generate the files?

Thanks.

-- Ben

Yes, you can safely ignore this comment as the tools which manipulate
the MLT files no longer exist.

n.b. the eCos sources and build system only use the .h and .ldi files

Great, thank you.

On another note, in the course of migrating our ECOS 1.3.1 based Redboot 
to the newest ECOS sources, there is a configuration bit missing in 
SDRAM register definitions located the hal_ixp425.h chip header file.

#define SDRAM_CONFIG_64MB          (1 << 5)

That line exists in the 1.3.1 based hal_ixp425.h file that we have - I 
don't know if it was put in by one of our previous developers, but it is 
a valid configuration bit listed in the datasheet (that we require) and 
should logically located there. Who do I refer the fix request to?

Thanks.

-Ben

Send patches to ecos-patches@ecos.sourceware.org.  They'll be reviewed
and committed as appropriate.
