Is uBoot OS specific? June 14, 2017 05:25PM |
Registered: 6 years ago Posts: 337 |
I don'know anything about uBoot, and I'm not sure if my understanding of it as a Universal boot loader for embedded ARM systems is correct. If that is the case, then presumably the same uBoot can load any OS which works on the platform, not just Debian, but also ArchLinux and even (God forbid) Windows.
Is my understanding correct?

u-boot will load and run virtually all Linux distros (Debian, Arch, Gentoo, Fedora ....). But not Windows.

No. U-Boot is not OS specific. How you configure envs settings to boot certain distro is what make it specific.

For this question a simple google search came up with this but I can't speak of it from experience.

balanga,
feas has covered the rootfs part.
Now the boot loader part is not comlicated. You have installed a new u-boot (mine or Arch does not matter), it will most likely boot FreeBSD rootfs with some simple changes in u-boot envs. But first I need to look at that the FreeBSD rootfs that you will have created, and give you something to try.
With that said, I would prefer that you boot in to Debian rootfs, and then update u-boot with my build so it will save me some time. But if you'd rather keep what you have then it is fine, too.

I'm more than happy to try. I'm more comfortable with FreeBSD - even have it running on my Raspberry Pi, and the ultimate goal was to have a FreeBSD based GoFlex Home unit. So tell me what I need to do and I'll give it a try.

This is from FreeBSD running on a Raspeberry Pi booted from a 32GB MicroSDHC card. There was no such directory as /lib/modules. Maybe what you want is called something else on FreeBSD. This will give you the layout of the filesystem on FreeBSD. Any applications which are not part of the core OS are installed under /usr/local

That's interesting. But what you should do next is googling "FreeBSD u-boot" to find out how other people did this.

To be quite honest, this is a very technical area, and most of the hits show pages which I don't understand. There are so many pages which span quite a period and relate to wide range of hardware that it is difficult to limit the search to my situation. I will study the link which you provided earlier and see if I can make anything of it,

There is really no hardware specifics in this. Basically you want to search for topics that peole discuss how to set up u-boot to boot FreeBSD. For example,
- Is the ubldr the boot file for FreeBSD?
- which file is FreeBSD kernel file?
- Where is the DTB? is it built in to BSD kernel file?
Things like that.

Sounds easy enough, uboot basically has to load "kernel.bin" to RAM and then just execute it. You seem to have a file called "kernel" in your boot partition so I guess it's that the one in more modern FreeBSD.
for example (from serial console, if from linux use fw_setenv instead of setenv)
setenv bootcmd 'usb reset; fatload usb 0:1 0x900000 /boot/kernel; go 0x900000'
would set your device for looking into first partition of first usb device, which is formatted as FAT32, and load a file called kernel from inside the /boot folder, and then plain execute it.
You can also make something more complex as stated in the link above, if you want it to be able to find the right USB drive if you have more than one connected. Or boot from Sata drives, just write "ide" instead of "usb" in the line above.
Or you can keep the whole /boot folder as a separate partition on FAT32 if you want to keep your rootfs on UDF or whatever other filesystem. In that case change the "/boot/kernel" from above into "kernel", and add a line in FreeBSD's fstab to mount that partition over /boot folder.
The hard part seems to be getting a freebsd kernel/OS compiled for it.
EDIT: saw your posts on bsd forum, add
V=s
as an argument to your make. That is verbose mode. It will allow you to see what is going on, as long as it keeps spewing text it's probably still working.

I've had a bit of a break from my GFH project, but having just seen your post, I thought I'd resume... Firstly, I'd just like to mention that I'm rather out of my depth trying to do what I'd want, which is to run FreeBSD on my GoFlexHome unit... Having searched various forums, websites, mailing lists, it seems like solutions exist, but instructions are not always up to date, or unclear.. My experience so far as shown me how to replace the stock Seagate software, lock myself out, connect via a serial cable and unlock myself. All this thanks to help from bodhi on this forum and the FreeBSD forum.
Reading your post, I take it that my first task is to try and build a FreeBSD image using instructions here:-
https://cooltrainer.org/freebsd-kirkwood/building/
Unfortunately some of the instructions don't work and they are based on FreeBSD v8 and the current release is v11...but I'll see how far I can get. I expect it will take me a few days to get anywhere with it.

Actually, that is a thread I started.... Having looked at building FreeBSD today, it looks like the latest FreeBSD source (v11.0) includes all the necessary source and no patches are required, as far as I can tell. What I need to figure out now is to install FreeBSD on a USB stick and launch it from U-Boot. Not sure if need a different U-Boot...

I think you also need to verify which are the boot files on the FreeBSD rootfs. I briefly searched for this topic, and I can see that a "ubldr.bin" or something like that is used in booting. This is most likely because u-boot mainline does not deal with FreeBSD directly, but it can load a binary and run it. So the "ubldr.bin" is a FreeBSD loader.

No, I'm talking about the latest RELEASE version:-
[url]http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/amd64/11.0-RELEASE/src.txz[/url]
Using:-
make buildworld TARGET_ARCH=arm -DWITH_FDT
make buildkernel TARGET_ARCH=arm KERNCONF=DB-88F6XXX
Unfortunately I don't know how to launch this, so I can't test it.

It does appear so. But, it contains the source code of $FreeBSD: releng/11.0/README 300137 2016-05-18 10:43:13Z avos $

There is also
http://ftp.freebsd.org/pub/FreeBSD/releases/arm64/11.0-RELEASE/src.txz
but it is the same file. There's only a single source tree.
Any suggestions as to what I should put in uEnv.txt to try and boot FreeBSD?
I've tried
uimage=/boot/kernel.bin
but get
reading /boot/kernel.bin
4408164 bytes read in 249 ms (16.9 MiB/s)
Booting from 0 ...
Wrong Image Format for bootm command
Where can I find a list of options which I can put in uEnv.txt?

balanga,
Please read what I wrote above. bootm is for Linux.
You need to do more research and find out how people boot FreeBSD with u-boot. If you are not sure that you understand those instruction, then post them here. Perhaps I can help that way.

I thought that the easiest way to understand how things work and make some progress would be load a file over the network and execute it...
If I run DHCP, I retreive a file called gpxelinux.0. The system displays:-
TFTP fromserver 192.168.1.2; our IP address is 192.168.1.47
Filename 'gpxelinux.0'
Load address: 0x810000
Loading: ########
5.3 MiB/s
done
Bytes transferred = 111334 (1b2e6 hex)
GoFlexHome>
What I thought I should be able to do was run this program using
go 0x810000
I get
## Starting application at 0x00810000
and then nothing. Not sure if what I'm attempting makes any sense or what myresults show...

I did some googling and foudn this How to build a FreeBSD toolchain for Linux and don't know if this may help or not. I basically is aguide on how to create a FreeBSD toolchain (v10) for Linux platform. once you have such a toolchain, perhaps building a FreeBSD will become more obvious?
