Thank a lot for the responses so far!
Is there a /etc/default/grub file
@mj5030 No.
mount /dev/sda1 /mnt
This way I found the /boot/
directory now But when looking at the current grub config this does have a timeout="5"
parameter already (line 5):
# cat /mnt/boot/grub/grub.cfg
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1 --rtscts=off
terminal_input console serial; terminal_output console serial
set default="0"
set timeout="5"
set root='(hd0,msdos1)'
menuentry "LEDE" {
linux /boot/vmlinuz root=PARTUUID=b3ade79d-02 rootfstype=ext4 rootwait console=tty0 console=ttyS0,115200n8 noinitrd
}
menuentry "LEDE (failsafe)" {
linux /boot/vmlinuz failsafe=true root=PARTUUID=b3ade79d-02 rootfstype=ext4 rootwait console=tty0 console=ttyS0,115200n8 noinitrd
}
So I do not think that regenerating would help. Could there be any other reason why LEDE stops/waits at the grub menu?
As said it used to be working for year or so and I have not done anything software like on the device (there only used to be an update on the Fritzbox sitting between the LEDE router and the Internet, but I do not think this should have any influence on booting of LEDE, right?!)
