[ECOS] Problems in building Redboot with ROM File System

[ECOS] Problems in building Redboot with ROM File System

[Manoj Abraham]

Hai,

    Thanks for your reply. I tried to include ROM File System package while building image for Redboot. I also included following packages


  1. IO Subsystem
  2. eCos Kernel
  3. C Lib
  4. Linux Comp.layer
  5. File IO
  6. Posix File IO Comp. layer

I have selected the Base of ROM FS as 0xFE10000

When I give build it is giving the following error

make[1]: Leaving directory `/working/xalted/test/b_build/redboot/current'
ecos-c/cygwin/working/xalted/test/b_install/lib/extras.o: In function `fcc_eth_RxEvent':
make: Leaving directory `/working/xalted/test/b_build'
/ecos-c/cygwin/opt/ecos/updates/ecos/packages/devs/eth/powerpc/fcc/current/src/if_fcc.c:515: undefined reference to `sscanf'
collect2: ld returned 1 exit status
make[1]: *** [/ecos-c/cygwin/working/xalted/test/b_install/bin/redboot.elf] Error 1
make: *** [build] Error 2


I am surprised to see that the file if_fcc.c doesnot use the fn sscanf()..

Can you please tell me what is the mistake I have made while selecting the pkges?


Thank you

This seems a bit strange to me, although not totally
unreasonable. Please could you explain why you want to do this. Im
just woundering if you don't fully understand the eCos architecture
and are making a mistake, or there really is a reason you need a ROMFS
in redboot.

        Thanks

You should be using jffs2, not ROMFS. ROMFS is not writable.

Also, you say 
"Application images, eCos Kernel"

You have the wrong idea here. eCos is statically linked to the
application, not a seperate thing like Linux. Also, eCos is quite
happy to run without what we call the kernel. ie you can run eCos with
just the HAL and the device drivers. The normal redboot configuration
for example does not have the kernel.

[Manoj Abraham]

Thanks for your kind advice.My answers for your questions are

 
1. What do you want to place in this   filesystem?

    Application images, eCos Kernel

2. It is read only or do you need to be able to write to it?
 
    Read/Write

3. Does it only contain your application image you want Redboot to boot?

    yes

4. Or is it a filesystem for your application?

    yes

5. Or is it a combination of both? 

    yes

A ROMFS does not sound right. A JFFS2 filesystem seams more reasonable
and that will work with Redboot. 

Its back to my first question. What are you trying to do? What do you
want to place in this filesystem? It is read only or do you need to be
able to write to it? Does it only contain your application image you
want Redboot to boot? Or is it a filesystem for your application? Or
is it a combination of both? 

Once we understand what you want to do we can advise you the best way
to do it. 

        Andrew

Use RedBoot's Flash Image System.  This lets you manipulate the FLASH
(ROM) space from the RedBoot command line. FIS images can contain
anything, including file systems.  You can then write your eCos
application to access the file system (ROMFS or JFFS2) from the
FLASH.

RedBoot should *not* be build with ROMFS included.

[ECOS] Re: Problems in building Redboot with ROM File System

[Manoj Abraham]

I am able to boot the board and got Redboot prompt. Now I want to implement the Flash File System. I built a romfs image using mkfs.exe(in fs dir).In mkfs docs they have mentioned about setting a ROM BASE ADD in config tool.So I included ROMFS in Redboot and other pkgs for removing the conflicts. I need a ROM FS becoz my board is having 32MB. I want to use a file system for this area. Is it make a problem while adding the ROMFS pkg along with Redboot?Or can you suggest me the right method for this?
