Append bootargs to Grub

Board Integrations Yocto Project

Hi,

Simple question, I recently tested mender on a QEMU machine, but I don’t see how to append “nofg” to kernel bootargs.

I tried to add
MENDER_GRUB_KERNEL_BOOT_ARGS = “nofb”

To my machine but didn’t have any effect.

I’m on Zeus release,
Thanks for your help.

can your confirm that the arg is making it all the way thru to runtime?

cat /proc/cmdline

[    7.236330] uvesafb: 5000 ms task timeout.
[    7.236690] uvesafb: Getting VBE info block failed (eax=0x4f00, err=1)

[    7.238584] uvesafb: probe of uvesafb.0 failed with error -22

$> cat /proc/cmdline

BOOT_IMAGE=(hd0,2)/boot/bzImage root=/dev/vda2 console=ttyS0,115200n8 rootwait

Just to be more clear, I don’t use mender-convert.

I build a Yocto image with machine=qemux86-64 and inherit mender-full.

are you using uboot as your bootloader then, as it looks like MENDER_GRUB_KERNEL_BOOT_ARGS is a mender-convert variable.

If using uboot, in the past i have added a patch to add in the CONFIG_BOOTARGS variable to the uboot recipe which meta-mender honours

I’m using grub as bootloader for my VM… :frowning:

maybe you can .bbapend the meta-mender grub recipe to append to the console-bootargs variable, (add another grub config file with larger number prefix to add to the console-bootargs variable)
