Title: How can I make proper core.gz of Raspberry Pi?
Post by: Akane on May 26, 2013, 12:05:33 AM

Hi all.

I would like to use my remastered initramfs, core.gz.
I know the procedure of making core.gz is below(according to wiki):

Code: [Select]

# cd coredir
# find | cpio -o -H newc | gzip -c9 >../rpicore.gz
But it doesn't work. Kernel was panicked.
The message is below:

Code: [Select]

Kernel panic - not syncing: VFS: Unable to mount root fs...
So I would like to know how to make proper core.gz.

Thanks,
Akane.

Did you set the length in cmdline.txt (initrd=...)?

Hello bmarkus.

Oh! Thank you for your advice!
I didn't know the 2nd parameter of initrd= of cmdline.txt is the core.gz's file size.
Now it booted properly.

Thanks a lot!
