hi all MT gurus,
i have problem to upgrade the OS .i have 2 RB532A and both have same problem.
if any one help me then i m very thankful.

i can not login through winbox.so i try to login through console.but it gave me following error:



Press any key within 2 seconds to enter setup..
trying bootp protocol... OK
Got IP address: 192.168.1.1
resolved mac address 00:15:58:DC:8C:1D
transfer started ..................... transfer ok, time=0.94s
setting up elf image... OK
jumping to kernel code
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)[/b]

so is there any solution for that?
i try my all possible way.but no luck.

regards,
vipul

Have you tried formating the nand first? The BIOS should have an option to do this. Then try a netinstall again. Also it may be wise to do a memtest (m)... which I think is also included in the BIOS.

thanx dear
i already format nand.but no luck .

so whats the problem?
i can not use routerboard more?

Can you successfully do a netinstall?
Could there be a BootP server hijacking the boot up? You may want to set the nand as the first boot device instead of the network card after you have completed the netinstall.

I had the same problem as your newest post, which I resolved by check marking "Bootp support" in the definition of the DHCP server. My DHCP server is Miktorik ROS as well. I'm not sure how to set that up in another type of DHCP server.
