Hi!

it is a way to set my rb800 to try a ethernet boot then nand?

the idea is to when i need to netinstall the rb on a tower just restart the unit.

Thanks in advance.

RouterBOARD configuration,

system routerboard settings set boot-device=
ethernet    flash-boot-once-then-nand   nand-only                  
flash-boot  nand-if-fail-then-ethernet  try-ethernet-once-then-nand

try-ethernet-once-then-nand - it tries Ethernet for the first boot and then changes to NAND.
nand-if-fail-then-ethernet - it uses Ethernet for boot, when boot from NAND fails.

i know but… next reboot the setting goes to the default… it´s normal?

Yes,

it is the reason, boot-setting has name try once.

nand-if-fail-then-ethernet should be saved after any reboot.

the idea is to the rb always boot from nand.

but on every restart check if there is a netinstall service running.

my rb800 had 3 times a “kernel panic” and i had to climb up to my tower to pick the rb near my computer.

the rb800 have ros4.16 and now i have put the latest beta to test if problem was solved.

the idea is to check one time for ehthernet boot then nand, but if i power off (on the POE) had the possibility to netinstall more “easy” .

it is possible?

or/and can you add possibility to change the boot loader configuration from the running ROs ?

thank you very much for the comments.
We will see what we can do.

gzohop
/system routerboard settings set boot-device=
allows you to change boot-device from RouterBOARD console.

Thanks
I missed that, I assumed that there is no such possibility because on every Netinstall howto’s I have seen just info about RS cable or the button(RB711 etc ) :slight_smile:
