Fallback option does not work on grub

Hello everyone;

We are looking for fail-safe boot-up strategy for our product based on Intel quark.We have been use the "meta-intel-quark" meta-layer for grub.

Now we are adding the "fallback" option in "grub.conf" file as below;

default saved

timeout 10

fallback 1

color white/blue white/cyan

title Quark X1000 First-kernel-MassStorage initrd-MassStorage RootFS-MassStorage IMR-On IO-APIC/HPET NoEMU debug

root (hd0,0)

kernel /bzImage root=/dev/ram0 console=ttyS1,115200n8 earlycon=uart8250,mmio32,$EARLY_CON_ADDR_REPLACE,115200n8 reboot=efi,warm apic=debug rw LABEL=boot debugshell=5 rootimage=image-full-quark.ext3

initrd /core-image-minimal-initramfs-quark.cpio.gz

savedefault fallback

title Quark X1000 second-kernel-MassStorage initrd-MassStorage RootFS-MassStorage IMR-On IO-APIC/HPET NoEMU debug

root (hd0,1)

kernel /bzImage root=/dev/ram0 console=ttyS1,115200n8 earlycon=uart8250,mmio32,$EARLY_CON_ADDR_REPLACE,115200n8 reboot=efi,warm apic=debug rw LABEL=boot debugshell=5 rootimage=image-full-quark.ext3

initrd /core-image-minimal-initramfs-quark.cpio.gz

savedefault fallback

But after added this option board is not boot and it show the error message as below:

Error 15: File not found

Quark GRUB Recovery shell

[ Minimal BASH-like line editing is supported. For the first word, TAB

lists possible command completions. Anywhere else TAB lists the possible

completions of a device/filename.]

Hi Nikunj,

May I know, do you able to boot to partition root (hd0,1) ?

This is other partition on the same device.

It is mean, your device has 2 partitions. (hd0,0) and (hd0,1) have 2 separate systems.

Do you try to set (hd0.1) as your second devices? Could be you have two USB or SDCARD?

Thanks

Hello mohamedshaharris;

Thanks for your reply and sorry for late Reply.

We are able to boot the partition root(hd0,1).

We had been created the second partition on sdcard for backup. We are using only sdcard not USB.

Thanks and best regards;

Hi Nikunj,

Do you still see the "Error 15: File not found"?

Since you mention you were able to boot the partition root(hd0,1).

Hello mohamedshaharris;

Thanks for your reply and sorry for late Reply.

We are currently not use the savedefault fallback option so we don't have "Error 15: File not found" Error. but we need to use the savedefault fallback option in our product. whenever we use this option in our grub.conf file we found "Error 15: File not found" Error.

Thanks and best regards;
