You can try grub_printf instead of grub_dprintf. -----Original Message----- From: Help-grub [mailto:[email protected]] On Behalf Of shenbagaraja s Sent: Thursday, July 19, 2018 3:08 PM To: [email protected] Subject: How to debug GRUB2 if my grub_dprintf is not working ?
I am facing issue in my server which is hanging up everytime on grub shell. And I am trying to debug this grub2 issue by adding grub_dprintf. But those printf statements whatever I added are not visible in the console. I also tried "set debug = all" from the grub shell prompt. Is there some other way of adding the debug prints inside grub2 source? Also I would like to know about how to debug Grub2 issue from using GDB? My GNU GRUB version is 2.02~beta and OS is RHEL 7.4 Could anyone help on this?
