I have a rb433AH that wont boot up. I can see on the serial port it say nand bad. I can go into setup and tell it to boot from Ethernet. I don't know what the ip address of the board is so it won't talk to netinstall.

Thanks

David

You should be able to reformat your nand from serial and enable boot from Ethernet once then nand.

You can then use netinstall to via RB433's ether1.

Your PC should be directly connected and have a static IP address assigned to it's Ethernet.

In netinstall under netbooting you need to specify an address in the same subnet as the pc is configured to it.

see http://wiki.mikrotik.com/wiki/Manual:Netinstall

but the RB won't have an IP address. how can netinstall talk to the RB? I can set the computer to any IP address since it is directly connected to RB.

Thanks

Netinstall assignes ip to device when performing startup. No need to make any settings on device if it should be netinstalled.

so what ip address to I give my computer so it is on the same subnet as RB?

assign your pc 192.168.88.254 subnet 255.255.255.0 no gateway needed.

In NetInstall under netbooting put 192.168.88.2

I have formated nand.

I have notebook pluged into poe and have notebook ip address 192.168.88.7 with 255.255.255.0 netmask

I have told netinstall to try 192.168.88.1 and .2 but it just keeps rebooting when it can't fine netinstall.

Somehow a ip address needs to be put into the RB. without one how can it connect to netinstall?

Thanks

David

@gcs
For succesful netinstall connect your RB via Ether1, on other ports netinstall doesn't work.
I've netinstalled RB433AH in my office two weeks ago, without problems.

HTH,

ditonet is 100% correct. ether1 should be labelled POE/BOOT on the RB433. NetInstall will only work with on a port labelled POE/Boot. Refer www.routerboard.com and download the user guide for your router if unsure.

I am using Eth port 1 through the POE. I have boot from eth set and it tries to boot from ethernet but the notebook running netinstall never sees it.

Usually when i do a netinstall the RB is somewhat working and I can get in and set ip address to a known address. I then tell netinstall the ip address of rb and it works.

I don't think this RB has a default address in it. I guess netinstall can't see the rb. Is there anyway to use mac address?

I'm having problems with this too. For years I've been using NetInstall on several different RB types with no issues. Now however, I have a batch of RB433 boards coming in with ROS 5.26, firmware 3.18, and all of the half-dozen boards I've tested so far have refused to NetInstall as expected. I don't get the "NAND bad" message that David is seeing; in fact I see *no* serial output at all... which is preventing me from selecting the appropriate U-boot options to boot from NetInstall.

Since I can't get these boards to PXE boot, they boot to the installed ROS, but come up with a 0.0.0.0 Ethernet address. (This is no doubt why the BOOTP push button also fails to connect to NetInstall.) After playing around with them quite a bit (downgrading ROS, attempting to downgrade the firmware, using the BOOTP push button, etc., etc.) I have eventually been able to get all six boards to NetInstall but only after considerable effort with procedures that have varied from board to board. Once reinstalled with ROS 5.4 (and retaining the 3.18 firmware), they seem to function normally and the serial console once again displays as it should. The problem is the inconsistency of the steps it has taken to remedy these boards... and I have 26 more to do.

I'm pretty certain we're seeing a bug here. Normis, any suggestions? Is anyone aware of any work-arounds or do I need to send these back to the distributor?
