Timed out for editing-

As I was saying- I did not tell you to edit rcS like you have done it: You just need that ONE command line:

/bin/showlogo /var/etc/bild

and not the lines directly above and below it!! You are no longer mounting and unmounting the mtd6 cramfs partition, remember!

and all this for a logo you'll see only ones in a few months

[PaphosAL]

and all this for a logo you'll see only ones in a few months

Agreed, Hemertje- but for some people it's the challenge of doing it (and learning how to master the editing / modding of SquashFS in the process).

For others- it's to impress friends and family when they visit. And then I suppose there is a sub-species living in the mud at the bottom of the pond who want a different boot logo for entirely different reasons.

I sense that the OP is a hobbyist, like me, who is a fast learner. Unlike me, LOL! But remember what I suggested earlier in the thread- that you can replace the Radio Mode b/g picture with one of your own, for instance.. It's just fun, really...

Cheers- AL

thanks for clearing things up for me,
i will try again as you suggested.

all this is new to me, i've only been using linux/ubuntu for a day or two...lol
but i think i'm getting the hang of it.../images/smiley/smile.gif

o.k i have started everything again from the start.
firstly i have flashed the latest openpli-maxvar image.
i am using the desktop as my working directory.
so then, i used ./squazma OpenPLi.img which produced the squashfs-root folder.
the following is displayed in the terminal window:

jim@jimmy-ubuntu:~/Desktop$ ./squazma OpenPLi.img

then i edit the /etc/init.d/rcS files and replace the three lines with /bin/showlogo /var/etc/bild and save the file.
then i used ./squazma -c which produced a mtd-root.img on the Desktop.

then i ftp the mtd-root.img file to the /tmp folder on the dreambox and use the following command:

cd /tmp && eraseall /dev/mtd/5 && cp mtd-root.img /dev/mtd/5 && reboot

when the box reboots i check the /etc/init.d/rcS file and can see the changes made in that file.
i then ftp your bild file into /var/etc and reboot the dm500s.
when the dm500s reboots i get a black screen where the bootlogo would show up but the menus and everything else work fine.

i'm pretty sure i've done everything right this time, but still no bootlogo .../images/smiley/sad.gif

[PaphosAL]

Good- that all looks sound. But it remains a mystery why the test logo works for me, but not for you. I uploaded it as a WinRAR archive; I take it you ARE using WinRar to extract the bild file first, and that you haven't transferred bild.rar to /var/etc 'as' bild ???

If so, then please attach a copy of your edited rcS in zip or rar form for me to check.

Thanks- AL

[mamujim]

yes, i have extracted the file from bild.rar using ubuntu.
if i play the bild file in ubuntu i can see the commando logo.

can you please confirm that you have done the same using the latest openpli maxvar image and the logo works for you?

i will attach the rcS when i finish work.

btw i am just a hobbyist doing this for fun and a challenge /images/smiley/grin.gif

cheers

[mamujim]

please find attached the edited rcS file.

It's OK, I think we have nailed the problem. I asked LraiZer to browse this thread, and he spotted something vital missing, that I'd forgotten all about...

Basically, it's a conflict of Ownership problem in Ubuntu, which LraiZer cured in this line of the squazma script, by adding the bit in red:

./mksquazma squashfs-root mtd-root.img -be -all-root

Just to be sure, I've attached a new Squazma Tools fileset that incorporates this tweak. I'm sure this will resolve your problem, m8.

excellent, can't wait to try it when i get home. /images/smiley/grin.gif
so do i still use ./squazma -c or do i use ./mksquazma squashfs-root mtd-root.img -be -all-root , they will both do the same thing right?
i got told off for using the later syntax earlier.....lol
Big thanks to PaphosAL and LraiZer for all your help.
i think i'm getting the hang of this linux/ubuntu system. /images/smiley/smile.gif

[PaphosAL]

I strongly recommend that for the root image recompile, you stick to the ./squazma -c command from the Ubuntu terminal console.

[mamujim]

arrrrrrrrrgh, still not working !!! /images/smiley/angry.gif

[PaphosAL]

One last try, as I'm clutching at straws now, LOL! Move your new line in rcS from where it is now (near the top) down to almost near the bottom, like so:

/bin/showlogo /var/etc/bild
exec /bin/start_enigma

exit 0

I think the issue is to do with trying to access the var partition, before it's even been mounted. I have a good feeling about this now, so give it a go, please.

Cheers- AL

[mamujim]

now we're getting somewhere...lol

tried as suggested and the commando logo is displayed /images/smiley/grin.gif but it is corrupted /images/smiley/more_sad/6.gif
so looking at the rcS file, i put it under the line where the var partition is mounted, so it's at the start and not the end

echo Mounting /var
/bin/mount -t jffs2 /dev/mtdblock/1 /var
/bin/showlogo /var/etc/bild

but still corrupted bootlogo.

can you please check your rcS file to see where your /bin/showlogo..... line is?

thanks again for all your help so far.

[hemertje]

define corrupted?

[mamujim]

top few lines and bottom few lines of the picture displayed with black blocks on the rest of the screen.

[WanWizard]

How did you create the logo? It should be a 1-frame mpeg2 file.

[mamujim]

created using tmpgenc as described earlier in the thread.
can i extract the mtd6 cramfs kernel partition and replace /root/root/platform/kernel/bild with my own bootlogo then recompile and flash mtd6 partition back?

Yes, you could do it that way, but be very careful to make sure your new logo is not larger than the PLi original you intend to replace! The cramfs mtd6 partition must not exceed 0x100000 Hex (1,048,576 bytes) in size.

In my rcS here, I have the showlogo line near the bottom, like I showed you. You could also try removing it from rcS altogether, and pop that line into /var/etc/init - which is called from rcS (if it exists) during boot. Note that init will only carry that one single line, (unless you already have an init file, in which case you append the line) and it can stay at the default chmod 644 permissions.

Cheers- AL

[mamujim]

is there a squazma equivalent for cramfs ?
will try adding the line to /var/etc/init tonight.
