Subject: actual mtd snapshot and jffs3 questions
Date: Thu, 23 Dec 2004 15:51:19 +0100 [thread overview]
Message-ID: <20041223145115.GA14940@synertronixx3> (raw)
Hi People!
Today I tried out the actual mtd cvs including jffs2 and jffs3.
Generally jffs2 works.
I switchied compiling of jffs3 on also to test it
but in jffs3.h are #ifdefs in the lines 296 and
310 which I had to comment out.
#if defined CONFIG_JFFS3_FS_NAND || defined CONFIG_JFFS3_FS_NOR_ECC
Indeed I have no CONFIG_JFFS3_FS_NAND nor CONFIG_JFFS3_FS_NOR_ECC but
the code required the members of the struct and compiled fine then.
Another thing is:
make -C util
make: Entering directory `/usr/src/mtd/util'
gcc -I../include -O2 -Wall -g -c -o sumtool.o sumtool.c -g
-Wp,-MD,.sumtool.c.dep
sumtool.c:45:24: jffs3-user.h: No such file or directory
which is right, no such file :) Forgot cvs add?
How do I use jffs3? With a normal jffs2 filesystem created by actual
mkfs.jffs2?
I found no mkfs.jffs3 so I tried setting rootfstype=jffs2 to
rootfstype=jffs3 and booted:
