I am updating our yocto based system from fido to morty. I am building VMware image and everything works fine, the system builds fine and boots succesfully.
The problem is that in now that I have updated the system (didn't happen in fido) I'm getting options to choose from when starting the virtual machine:
Select kernel options and boot kernel
Graphics console boot
Serial console boot
press [Tab] to edit, [Return] to select
if I choose to edit the options I can see that the options correspond to kernel options as follows:
Graphics console boot: /vmlinuz LABEL=boot root=/dev/sda2
Serial console boot: /vmlinuz LABEL=boot root=/dev/sda2 console=ttyS0,115200
If I don't choose anything it chooses Graphics console boot automatically, which is good since that's the one I want.
BUT I'd like to know how to override this and just immediately select the graphics console boot and start the boot.
I found that the options are defined in /poky/tree/scripts/lib/wic/canned-wks/directdisk-bootloader-config.cfg
I also noticed that the serial console is not defined in morty, which also confuses me, as I should not be seeing it since it's not in morty? But that's not the problem and I just want it to boot directly with the options /vmlinuz LABEL=boot root=/dev/sda2
So I eventually found the answer on my own. All I had to do was add
AUTO_SYSLINUXMENU = "0"
in
/conf/<machine>.conf
The variable is defined in /poky/meta/classes/syslinux.bbclass and has a description
${AUTO_SYSLINUXMENU} - set this to 1 to enable creating an automatic menu
