I have modified poky/meta/recipes-core/initrdscripts/initramfs-framework/init
to force a shell script when the "fatal" function is called:
# Prints a message and start a endless loop
fatal() {
echo $1 >/dev/console
echo >/dev/console
sh
#if [ -n "$bootparam_init_fatal_sh" ]; then
# sh
#else
#while [ "true" ]; do
# sleep 3600
#done
#fi
}
After regenerating the hddimage, adding "noapic" to bootargs and booting
the "install" option, I have a shell console available, but with a very
limited toolbox (cp, cat or even ls command are not available).
Some relevant error messages appear on the boot process. I copy theses
error messages by hand:
sd 0:0:0:0: Attached scsi generic sg0 type 0
sd 0:0:0:0: [sda] 234441648 512-byte logical blocks: (120 GB/1112GiB)
sd 0:0:0:0: [sda] Write Protect is off
sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't
support DPO or FUA
GPT: Primary header thinks Alt. header is not at the end of disk
GPT:1298455 != 234441647
GPT: Alternate GPT header not at the end of the disk
GPT: 1298455 != 234441647
GPT: Use GPU Parted to correct GPT errors.
sda: sda1 sda2 sda3
sd 0:0:0:0: [sda] Attached SCSI disk
After that, some "command not found messages"
/init: line78: touch: command not found
/init: line81: mkdir: command not found
/init: line82: mount: command not found
/init: line86: cat: command not found
/init: line98: grep: command not found
/init: line112: sed: command not found
And after all, this error message appears:
ERROR: Initramfs failed to initialize the system
Hope all this information can be helpful to fix this issue.
Thank you in advance! :-)
