Thanks! That cleared up a lot of confusion!
I still have a problem though.
After building the firmware I must sign it. According to the link it's done by writing:
signFW newFW.bin signature
However signfw is not a recognized command. What am I doing wrong.
Thanks for your help so far!

Hello there

Its a great Post and i started to do my own OSD. I prepared all my files, Pictures and so on for my OSD.
But now i got Problems with the rights to write in the XML and changing Pictures. I mounted the .bin file.. Opened the Folder and tried to change some Text in the XML and changing my pictures. But i cant save the Files cause i have no writing rights. I changed to chmod to -r 777 (is -r not only readable?) but nothing happens. When i try to copy the files to another place of the PC, but i have only empty files after copying.
I Know i make something wrong, but i dont know what exactly.

I tried to find a tut with step by step pictures, but couldnt find..

Would be great if anyone can help..

Thank you so much

Andy

not sure if it make a difference by linux is case sensitive,
I've always used -R (for recursive) and 777 (read/write access to everybody)

Im Using Kubuntu on my Acer Netbook, and same in a virtual Machine on my Laptop.

It´s a bit strange. So where could be the mistake that i cant get the writing rights to configure the files?

if you're trying to directly edit a cramfs bin it will never work, period, no matter what you change the permissions to. ext3 is for writing cramfs is read only.

I really dont know what im doing wrong. I cant get my files writable. Is there nobody who can help? Or maybe can someone upload the mounted Folder writable in a zip?
that would be really great.

Thank you so much

scoobydo: you are trying to write over files on a read only filesystem (cramfs is a read-only, compressed filesystem), and you can't overwrite the files with conventional methods.
You could convert the osd.bin you are trying to use from cramfs to ext3, and then it would be writable (and slightly larger). The way you would do the "conversion" would be to create a new ext3 filesystem and copy the files from the osd.bin to the new filesystem.

I haven't tried this, but try the following (change the path to your USB drive where appropriate):

Code: Select all

#create an empty file big enough to hold the osd.bin (16M)
dd if=/dev/zero of=/tmp/mnt/USB-UID/osd-ext3.bin bs=1M count=16
#create a new ext3 filesytem inside the file
mkfs.ext3 /tmp/mnt/USB-UID/osd-ext3.bin
#mount the new filesystem
mkdir /tmp/newosd
mount -o loop,rw /tmp/mnt/USB-UID/osd-ext3.bin /tmp/newosd
#copy the files over (assuming they are all under /osd - you need to check what files are exposed from your osd.bin)
cp -ar /osd/* /tmp/newosd
#sync
sync
#umount
umount /tmp/newosd


You will need to know the file structure of the original osd.bin and copy the relevant files to the new image. When you are done cloning the original one, rename it as osd.bin and reboot with it attached. Then, you should be able to overwrite the files you want.

Good luck!
