[Ltib] (ltib/fedora core 10) and (mpc8349itx/udev)

[aaron]

1)

Using Fedora Core 10 as a host development environment I checked out the
ltib from Savannah CVS, and in order to complete

./ltib --configure

I had to edit

dist/lfs-5.1/mtd-utils/mtd-utils-20060302.spec

and comment out the references to the first patch.

#Patch1          : mtd-utils-20060302-cf-byteswap_h-1.patch
...
#%patch1 -p1

I don't know if anyone else has gotten stuck here.

Also, getting udev to work for the mpc8349itx required a few workarounds. 
First I had to add a couple of files to the build so that the udev-fsl and
sysconfig-udev-fsl packages were selected instead of the defaults.

$ cat config/platform/mpc8349itx/pkg_map
source = pkg_map-mpc8349itx

$ cat config/userspace/pkg_map-mpc8349itx
PKG_UDEV = udev-fsl
PKG_SYSCONFIG = sysconfig-udev-fsl

Next I ran into a problem with the mount binary not being able to find
libblkid.so.1.  I had to make sure that "[*] Keep temporary staging
directory" was selected as part of ./ltib --configure so that my staging
directory wasn't deleted.  Then, I had to move my libblkid library and
links from rootfs.tmp/usr/lib to rootfs.tmp/lib, and rerun

Also, I had to edit the udev rules file to get my ttyS0 to show up so I
could log in.

rootfs.tmp.copy/etc/udev/rules.d/10-fsl.rules

#KERNEL=="ttyS[0-9]",    NAME="tts/%n",          SYMLINK+="tts%n"
KERNEL=="ttyS[0-9]",    NAME="tts/%n",          SYMLINK+="ttyS0%n"

One more thing I did which I'm not sure that I really need or not yet was
to add and entry for my mtdblock device in the device table min.  My root
file system is in flash.

$ cat bin/device_table_min.txt

#<name>         <type>  <mode>  <uid>   <gid>   <major> <minor> <start> <inc>   
<count>
/dev            d       755     0       0       -       -       -       -       
-
/dev/null       c       666     0       0       1       3       0       0       
-
/dev/console    c       666     0       0       5       1       -       -       
-
/dev/tty        c       666     0       0       5       0       -       -       
-
# CHANGE: adding this until I can figure out the udev stuff
/dev/mtdblock   b       640     0       0       31      0       0       1

After that I reran the mkfs command and this seemed to work.

$ /opt/ltib/usr/bin/mkfs.jffs2 -n -p -D bin/device_table_min.txt  -U -b -e
128 -d /home/aaron/ltib/rootfs.tmp -o ./rootfs.jffs2

I don't know if anyone else could find this helpful or has gone through
the process of getting udev to work with mpc8349itx, but I'd be curious to
know.
