howto configure redboot for jffs2

howto configure redboot for jffs2

[Raghu]

Hi, 
Refering mailing list archieves I am following these
steps for configuring JFFS2 on ixdp425 eval board.

$ ecosconfig new ixdp425 redboot
$ ecosconfig add memalloc io fileio error linux_compat
jffs2 ( David's mail 29 Nov 2003 ).
$ ecosconfig import $ECOS_REPOSITORY/package/hal/
arm/xscale/ixdp425/current/misc/redboot_ROM.ecm
$ ecosconfig tree ; make

I get this compiler error, 
-----------------------------------------------------
xscale-elf-gcc -c  -Wp,-MD,src/fs/fileio.tmp -o
src/fs/redboot_fileio.o /ecos-c/projects/ECOS/ecos \
packages/redboot/current/src/fs/fileio.c

rent'
make: *** [build] Error 2
------------------------------------------------------
I also tried Gary's inputs suggesting changes in the
redboot_ROM.ecm file, again resulting in same compiler
errors. 
Are there missing steps ? Do we have a consolidated
howto ?
Rgds,
Raghu.

You also need the kernel, crc and zlib.  Im supprised you did not get
an error about unresolved dependances etc.... You did you just ignore
the error?

Hi, 

Yup kernel, crc & zlib were added, 
$ ecosconfig new ixdp425 redboot
$ ecosconfig add memalloc io fileio error linux_compat
  kernel crc zlib
$ ecosconfig import ...\redboot_ROM.ecm
$ ecosconfig tree; make

I dont get any unresolved symbols for crc and zlib. 
Using this redboot I did, 
RedBoot> load -m xmodem -r -b 0x200000 jffs2_be.img
Redboot> fis create -b 0x200000 0x20000 jffs2
Redboot> mount -f jffs2 -t jffs2

At Flash address 0x50040000 it has 0x1985 ( Magic ).
Redboot> mount -t jffs2 -f jffs2
I get error,
<5>jffs2_scan_eraseblock(): Magic bitmask 0x1985 not
found at 0x00000368: instead.

But if I do, "ls" 
Redboot> ls
I get, 
RedBoot> ls
directory /
   1 drwxr-xr-x  1 size      0 .
   1 drwxr-xr-x  1 size      0 ..
   2 -rw-r--r--  1 size    476 group
   3 -rw-r--r--  1 size    677 passwd

Writing an application, I want to read the "groups"
file using, 
mount( CYGDAT_IO_FLASH_BLOCK_DEVICE_NAME_1, 
       "/", "jffs2" );
fp = fopen( "group", "r" );

But the fopen fails all the time, also tried with
"/group". 

If I use the jffs2_1.c test application, I cant get
any dumps on the serial console. Is there a console
setting ?

Awaiting valued technical inputs. regards.
