How can I debug the grub2.02?

[Sherry Zhang(BJ-RD)]

Hi all,

Platform : i386-pc

Grub2.02

 

I run into a error while I am testing.  I have found that it is normal berfore BIOS using the INT19 . But when the linux OS System is booting , I can see the error log.

So I doubt the error happens when the grub is running.

If I want to debug grub, how can I see the booting log of the boot.img and core.img?

For example :

Grub-core/kern/main.c

grub_boot_time ("After loading embedded modules.");

How can I see this log?

 

Best regards,

Sherry Zhang
