Built-in initrd inside kernel

[Soham Sinha]

I am configuring Linux kernel config (with menuconfig) to have initrd inside the kernel image. I change the CONFIG_INITRAMFS_SOURCE to a directory pointed by the initrd-content. I get the initrd-content by unzipping the initrd.img generated by Android_x86's $OUT directory. I use the following commands to create the initrd-content directory: mkdir initrd-content; cp initrd.img initrd-content/initrd.img.gz; cd initrd-content; gunzip -v initrd.img.gz; cpio -i < initrd.img

However, when I compile the iso_img, the Live Android is failed to work. It's giving me the following error:

Warning unable to open an initial console.
Kernel panic - not syncing Attempted to kill !init exit code=0x0000200

Kernel offset: .... 

 

How do I build the Android x86 iso_img with a built-in initrd in the kernel?

Why did you want to do that?

I was trying a different own bootloader which do not work well with external initrd. I finally got it to working. I needed to add a /dev folder inside the initrd-content folder add two nodes console and tty.
