Hello,
I tried to upgrade from 5.15 to 5.18 but the RB would not boot afterwards. When I connect to the console I saw a message that said it could not load the kernel.
RouterBOOT booter 2.36
RouterBoard 411U
CPU frequency: 300 MHz
Memory size: 32 MBPress any key within 2 seconds to enter setup..
kernel not found
trying dhcp protocol… OK
resolved mac address 52:54:00:17:56:C3
Gateway: 10.19.69.1
transfer started udp error 1
kernel loading failed\0x00
I tried netinstall but it did not detect the RB. I then chose the backup-booter but now it only displayes a “\0x00” and nothing else. Is there a way to recover from this? I tried the hard reset but that does not seem to work.
Select which booter you want to load:
- 1 - load regular booter
2 - force backup-booter loading
your choice: 2 - force backup-booter loadingRouterBOOT-2.36
What do you want to configure?
d - boot delay
k - boot key
s - serial console
n - silent boot
o - boot device
u - cpu mode
f - cpu frequency
r - reset booter configuration
e - format nand
g - upgrade firmware
i - board info
p - boot protocol
b - booter options
t - do memory testing
x - exit setup
your choice: x - exit setup
