Is uBoot OS specific?

balanga,

You did not run it the way I posted above

Quote

And then at serial console, instead of running picocom/putty/screen, run kwboot:

./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.05-tld-2.goflexhome.mtd0.kwb -p

After u-boot has been loaded, interrupt serial console at the countdown and,

help
help bootelf
printenv

Hopefully we will see the bootlef command in the help listing.

So you were never in kwboot.

Changing to /dev/cuaU0 is fine, since that's your USB device as detected by the system. But "| tee" is not OK.

"| tee" was only put in to get a log... This time I used 'script' to create a log, but ran this command

./kwboot -t -B 115200 /dev/ttyUSB0 -b uboot.2017.05-tld-2.goflexhome.mtd0.kwb -p

I don't see any difference, so either something is incorrect or I'm misunderstanding what you are asking me to do....

The date of the u-boot you are running is not what bodhi has provided. So is there and error displayed before it defaults to the installed u-boot? Perhaps in the previous file you piped the results to to see?

Can someone tell me what I should be seeing as I'm confused at this point. Presumably I should have my FreeBSD USB stick inserted when I power on my GFH dock, having previously started kwboot on my laptop. Should I see the new U-boot immediately?

There is also the possibility that my kwboot, which I built myself does not work properly... Is there any debugging facility to see if it is actually working properly?

Show all the info on the screen when you run kwboot incliding the command you typed such as:

./kwboot  -t -B 115200 /dev/ttyUSB0 -b uboot.2016.05-tld-4-rc6.dreamplug.mtd0.kwb   -p

The problem was probably with my kwboot....

That looks like just a bad connection. Trust me I have had plenty of them.


You should be able to just copy and paste from the terminal window.

Can I use this method to update the U-Boot on my GoFlexHome once it has booted?

No kwboot is to test if a proposed u-boot will work so as not to risk bricking your device.

balanga,

As feas said, it is best to copy what's in the terminal to a note you opened in an editor. When you run kwboot, it should be the only thing running in that command.

> Seagate GoFlex Home

Congrats! you are running new u-boot.


> GoFlexHome> help
> bootelf - Boot from an ELF image in memory

And the bootelf comand is available now.

The next step is to:

- Keep booting this way, and enter u-boot commands to try loading FreeBSD. I will post the commands.
- In the mean time, whatever you do here do not execute saveenv. Doing this will mess up your box.

Once you get it booting into BSD, you can flash u-boot in its shell. The commands should be similar to Linux.

bodhi's corner (buy bodhi a beer)

balanga,


1. kwboot with uboot.2017.05-tld-2.goflexhome.mtd0.kwb like you did before.

2. Interrupt serial console at countdown and execute the following commands (copy and paste each line to the u-boot prompt).

setenv bootfile ubldr
setenv fdtfile kirkwood-goflexhome.dtb

setenv kernel_addr_r 0x01000000
setenv loadaddr 0x02000000
setenv pxefile_addr_r 0x00100000
setenv ramdisk_addr_r 0x02100000
setenv scriptaddr 0x00000000
fdt addr 0x100

setenv bootcmd 'usb start; fatload usb 0:1 ${loadaddr} ${bootfile} && bootelf ${loadaddr}'
printenv
boot

See how far you will get.

Please post the entire serial console log (from kwboot command to the last line you see on your terminal).

Very encouraging! let me post another revised set of envs. There are preset envs that we did not have.

FreeBSD/arm U-Boot loader, Revision 1.2

(root@Multiboot, Thu Jul 20 09:36:42 BST 2017)

DRAM: 128MB

Number of U-Boot devices: 2

U-Boot env: loaderdev='usb 0:1'

Found U-Boot device: disk

  Checking unit=0 slice=1 partition=<auto>... good.

Booting from disk0s1:

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

loader> boot

|#/#-#\#|#/#-#\#|#can't load 'kernel'

no bootable kernel

Almost there!

Not sure if something is missing from the environment, or whether there is something missing from the USB stick. There is a 'kernel' file in the root of the FAT partition, so I'm not sure whether there is something wrong with it, or whether U-boot can't load it.

Good progress! Now we know that there are a few default envs that the ubldr expects, such as loaderdev.

The kernel file was not found, or an env needed to be defined.

Yes, almost there!

That kernel file was what ubldr looking for, and could not find it!

Could you compare the location of your BSD kernel file and the rPi kernel file, see if they are at the same location?

I also need to look at the rPi envs again.

balanga,

There are 2 files that needed to be where they are in the rootfs:

/boot/kernel/kernel
/kirkwood-goflexhome.dtb

So check your rootfs to see if they are at those locations.

But the rPi instruction states:


https://wiki.freebsd.org/FreeBSD/arm/Raspberry%20P

Quote

A FreeBSD bootable image for Raspberry Pi has both FAT and UFS partitions containing the following files:

FAT Partition
bootcode.bin - First stage boot
start.elf - Second stage boot
config.txt - configuration for start.elf
rpi.dtb - FDT file loaded via config.txt
uboot.bin - Third stage: U-Boot loader
uEnv.txt - configuration file for U-Boot
ubldr - Fourth stage: FreeBSD bootloader
UFS Partition
/boot/kernel - dynamic kernel
... rest of FreeBSD ...

So the kernel file might be

/boot/kernel

These are the files on the RPi FAT partition:-

23/12/2016  08:21            17,900 bootcode.bin
23/12/2016  08:21         2,664,088 start.elf
23/12/2016  08:21         3,621,768 start_x.elf
23/12/2016  08:21           567,672 start_cd.elf
23/12/2016  08:21               103 config.txt
23/12/2016  08:21             9,590 rpi2.dtb
23/12/2016  08:21           301,088 u-boot.bin
23/12/2016  08:21           231,800 ubldr.bin
23/12/2016  08:21           283,886 ubldr
23/12/2016  08:21             6,161 fixup.dat
23/12/2016  08:21             9,214 fixup_x.dat
23/12/2016  08:21             2,366 fixup_cd.dat
23/12/2016  08:21               607 README
23/12/2016  08:21             1,447 LICENCE.broadcom

As you can see there is no 'kernel' although config.txt contains:-

disable_commandline_tags=0
device_tree_address=0x100
device_tree=rpi2.dtb
kernel=u-boot.bin
gpu_mem=64

> I also need to look at the rPi envs again.

Also remember that the RPi card uses a FreeBSD U-Boot.

I presume this is what I have as db88f6281.dtb....

No more progress to relate at the moment. It seems like a FreeBSD problem now, since it is actually getting loaded.


Just wondered if it's possible to enter the parameters

setenv fatdev 'usb 0:1'

setenv loaderdev ${fatdev}
setenv bootfile ubldr
setenv fdtfile kirkwood-goflexhome.dtb

setenv kernel_addr_r 0x01000000
setenv loadaddr 0x02000000
setenv pxefile_addr_r 0x00100000
setenv ramdisk_addr_r 0x02100000
setenv scriptaddr 0x00000000
fdt addr 0x100

setenv bootcmd 'usb start; fatload ${fatdev} ${loadaddr} ${bootfile} && bootelf ${loadaddr}'
printenv
boot

in an automated way - entering each one individually via clipboard is proving error prone.

On the FreeBSD forum, someone pointed this out which may be useful...

https://wiki.freebsd.org/FlattenedDeviceTree#Using_loader.288.29

I'll investigate this later

Sure. It's now time to scritp them. I'll write a short description how.

Many thanks!

The FreeBSD build calls the DTB db88f6201,dtb. Does its name matter?

Yes it does.

Please get the lisiting of all files in the top 2 level of directories on your GF Home FreeBSD rootfs and post here. If there are too many files, you can pastebin and post the link here.

That's one of the problems, I don't really know... According to this guide - which which I've been trying to follow and which is several years old

https://cooltrainer.org/freebsd-kirkwood/building/


Install the kernel

 mount -t msdosfs /dev/da0s1 /root/usb
cp /usr/obj/arm/usr/src/sys/DOCKSTAR-COOLTRAINER/kernel.bin /root/usb
umount /root/usb

Install world

 mount /dev/da0s2a /root/usb
export DESTDIR=/root/usb
make installworld distrib-dirs distribution TARGET_ARCH=arm

So it looks like just a single file is copied to the boot partition. My build has a slightly different structure but the patches in the guide above have been folded into the mainline code, and it does create a db88f6201.dtb.. I haven't received any guidance from the author, but I'll try asking around since it appears that several people have this working.

> That's one of the problems, I don't really know...

Understood. That's why I' suggested just cd to to top level folder of the rootfs and list the files. For example, it the USB drive is mounted in another Linux/BSD box as /media/sdb1, then,

mount /dev/sdb1 /media/sdb1
cd /media/sdb1
ls -l

And 2 level of directories, because if a folder is relevant such as /boot or /kernel, then I need to see the file names in it.

For example, is the .dtb file in the top level directory? is there a file named "kernel"? is there a uboot.bin file and where is it? Are they at the same location in the rPi rootfs?

Because those are likely the relevant files that you'd need to script.

bodhi, if you can let me have a script, i can experiment by copying various files to my boot partition until I find some combination that gets me to the login prompt

As I see it you've already created a U-Boot which will load FreeBSD's uldr so can this be wriiten to nand? Presumably this can be updated if there are any modifications.

Once you booted into FreeBSD then you can flash it there. If this turns out to be a long delay then I'll write instruction to flash it in serial console.

BTW, and keep in mind that if you flash the new u-boot, the default envs will boot Linux. You will need to use the script to boot Arch or BSD. Until you can boot BSD successfully, you should not save envs.

On another box, download and copy the attached boot script uEnv.txt to your /boot directory in your FreeBSD rootfs 1st partition.

1. Insert the FreeBSD rootfs to the GoFlexHome. Run kwboot with U-Boot 2017.05-tld-2 (Jul 26 2017 - 02:37:42 -0700) GoFlex Home. And power up the GoFlex Home.

2. After kwboot has loaded the new u-boot, interrupt serial console and

setenv load_bsdenv 'usb start; load usb 0:1 0x810000 /boot/uEnv.txt; env import -t 0x810000 $filesize'
setenv boot_bsd 'run load_bsdenv; boot'

Once the uEnv.txt script has been loaded, list the envs to double check to see it the envs in this script were set correctly. And then boot

printenv
run boot_bsd

Please post entire serial console log here.

If FreeBSD is booted successfully, this u-boot can be flashed to NAND. Instruction will followed.
