tftpboot & loadderdev

Here is my latest attempt to boot a recently built version of FreeBSD/ARM for the GoFlex Home using tftpboot:-

Hit any key to stop autoboot:  0 
GoFlexHome> setenv serverip 192.168.1.1
GoFlexHome> tftpboot 900000 gfh2/ubldr.bin

FreeBSD/arm U-Boot loader, Revision 1.2

U-Boot env: loaderdev not set, will probe all devices.

Booting from net0:

can't load 'kernel'

Type '?' for a list of commands, 'help' for more detailed help.
loader>

This manages to run the FreeBSD boot loader, but I'm missing a couple of steps.

It seems that it is expecting a variable called loaderdev, so maybe I should have setenv loaderdev net0 or somesuch.
Still can't work out how to point ubldr.bin to kernel... would that be via DHCP using the filename and root-path options ?

balanga,

This is very important: I need to see the content of the FreeBSD rootfs built for armv5tel. For example, the rPi BSD rootfs is armv7.

Without seeing the information about the rootfs, I cannot advise you about how to load ubldr or how to set envs to boot this rootfs.

Now if you have not created that rootfs, then please go do that first.

If for what ever reason, you cannot find the information how to create this rootfs, then let me know. I might be able to help you look for it.

Hi, have you tried tftp booting the kernel directly? On the FreeBSD marvel page their example doesn't use the loader;

Booting FreeBSD on Marvell

Marvell>> tftpboot 900000 mv5281/kernel.bin

J,

That’s the old style of booting FreeBSD.

Ha! Sorry, I should have checked the age of their wiki guide.
