[ECOS] memory maps

[ECOS] memory maps

[hong zhang]

List,

I look at
http://ecos.sourceware.org/docs-latest/redboot/redboot-guide.html
and see memory maps like

Physical Address Range     Description
-----------------------   
----------------------------------
0x00000000 - 0x7fffffff    ATU Outbound Direct Window
0x80000000 - 0x900fffff    ATU Outbound Translate
Windows
0xa0000000 - 0xbfffffff    SDRAM
0xf0000000 - 0xf0800000    FLASH               (PBIU
CS0)
0xfe800000 - 0xfe800fff    UART                (PBIU
CS1)
0xfe840000 - 0xfe840fff    Left 7-segment LED  (PBIU
CS3)
0xfe850000 - 0xfe850fff    Right 7-segment LED (PBIU
CS2)
0xfe8d0000 - 0xfe8d0fff    Rotary Switch       (PBIU
CS4)
0xfe8f0000 - 0xfe8f0fff    Baterry Status      (PBIU
CS5)
0xfff00000 - 0xffffffff    Verde Memory mapped
Register


What redboot command can display memory maps layout?

Thanks.

None, sorry.  These maps were hand crafted :-)

Gary,

Do you know how atag works with redboot? Because I
want to make changes for virtual memory range.
Freescale recommends mem=64M@0x80000000
mem=64M@0x90000000 in command line. But people say use
atag is better.

Yes. It's all in CVS, just not checked out by default. Check out the 
ecos-host module, or at the top of your checkout (where the packages 
directory exists) do cvs update -d host

Is the source code of Configtool v1.3 available? I didnt thougt it was and
this is the only pace were the format of those mlt files is defined right?

Thanks.

If we can get the config tool v2 to build under cygwin (which we nearly 
can, but haven't yet :-( ) it will make it a lot easier to do this 
directly into the v2 tool, and maybe even to use that same code in a 
command line tool.

But ultimately it needs a bigger overhaul so that, for example, the 
various properties are exported into CDL too and can be used there.

There are a number of unnecessary restrictions in the code that "just" 
need to be fixed. It's open source so... :-).

RE: [ECOS] memory maps

Yep,

I was thinking of making a simple perl script to do it. Thats quite simple
for the .h file but not so simple for the .ldi file.

Also i noticed there are some things impossible to do with the configuration
tool.
In particular one cannot place a not relocated section just after the
initial place of  a relocated section.  If you try to do it, it will always
place itself after the final place of the relocated section. (That can be
usefull if you want to add a file at the end of your rom image and access
the file using a user defined section name...)

But unfortunately error-prone (whoever does it). I'm dreading the breakage 
when we eventually get a new MLT and regenerate the .ldi/.h files!

The MLT is AFAIK the only missing feature of the config tool v2 and we'd 
really like it to be there (or especially someone to pay for it!).

Ideally we could move to a more user-readable format and make it work with 
the CLUI tools too at the same time.

Sadly, no.  I just edit them by hand - it's not too hard.

[ECOS] memory maps

[Fabrice Gautier]

Hi,

Is there any other tool than the config tool v1.3 than can generate the
mlt_xxx.ldi and mlt_xxx.h files from a .mlt files?  I know its not yet in
CT2, but is there a command line tool for that ? I think not, but just want
to make sure.

Thanks
