can't enter console mode (Cntl + Alt + F2)

[ScottLiu]

Hi all,
I've done to build my own chromium os and install on USB stick, but :
1. it can enter console mode at booting from USB.
2. it can NOT enter console mode if I installed chromium os to HD.

Any suggestion would be appreciate, thanks.

1. Did you build your image as test image, dev image, or base image? (i.e., What complete command did you type when you do build_image?)

2. What firmware (BIOS) did you use to boot your Chromium OS? Is it ChromeOS-firmware (all Chromebooks), UEFI (many modern PCs), or Non-UEFI (old PCs, or new PCs configured to boot in legacy mode)?

    (To help figuring this out, try to think if you did see a GRUB menu when you boot the device)

thank for reply,
1. I totally follow Chromium OS dev guide, my build image command is "./build_image --board=${BOARD} --noenable_rootfs_verification dev"

2. My hardware is not Chromebooks. And BIOS is set for UEFI booting.

If your system is using UEFI boot, a GRUB menu should be displayed before starting Chromium OS.

Try press 'e' (to edit one entry) and see if you have "cros_efi" and "cros_debug".

[ScottLiu]

My system is SUSE + Chromium OS and GRUB was generated by SUSE's GRUB.

I edit 'e' to see and as attached file and I didn't found "cros_efi" and "cros_debug".

[Hung-Te Lin]

Sounds like you've installed your ChromiumOS in some non-standard way -- that's why you don't have the proper flags set in boot parameters.

You should add "cros_efi" and "cros_debug" to your kernel command line. i.e., 

... root=/dev/sdb3

to

... root=/dev/sdb3 cros_efi cros_debug

Thanks,it's work!
