These instructions document how FreeBSD (head) can be built for, and installed on the Helios-4. This has been made possible by the initial port of FreeBSD to the SolidRun Clearfog that has been submitted June 2017 by Semihalf and Stormshield: [Read the announcement here](https://lists.freebsd.org/pipermail/freebsd-arm/2017-June/016314.html).
|
||||||
|
|
||||||
|
## Compiling FreeBSD
|
||||||
|
There is a manual way to compile FreeBSD, and it is documented on the [SolidRun Wiki Clearfog page](https://wiki.solid-run.com/doku.php?id=products:a38x:software:os:freebsd). The process is almost identical for the Helios-4 in that a suitable DTB has to be copied to the boot partition.
|
||||||
|
The following instructions use the [crochet](https://github.com/FreeBSD/crochet/) utility for automating the build and imaging process.
|
||||||
|
|
||||||
|
### Get the source
|
||||||
|
We use a fork of crochet that has added the necessary bits for Helios-4.
|
||||||
|
```bash
|
||||||
|
mkdir work; cd work
|
||||||
|
git clone --checkout pr-clearfog https://github.com/Artox/crochet.git
|
||||||
|
svn checkout https://svn.freebsd.org/base/head src
|
||||||
|
```
|
||||||
|
|
||||||
|
### Configure the build
|
||||||
|
crochet uses a configuration file to perform builds. config.sh.sample is an example, and can be adapted as needed. As a bare minimum, a line
|
||||||
|
```bash
|
||||||
|
board_setup Clearfog
|
||||||
|
```
|
||||||
|
has to be at the top near the other commented board_setup_* lines.
|
||||||
|
In addition enabling the growfs feature has proven useful for autoresizing the rootfs on first boot: simply uncomment the line
|
||||||
|
```bash
|
||||||
|
option Growfs
|
||||||
|
```
|
||||||
|
|
||||||
|
There are plenty of other settings to change, but these suffice for creating a bootable image.
|
||||||
|
|
||||||
|
### Build
|
||||||
|
Navigate to the crochet folder, and assuming you called your config file config.sh, run:
|
||||||
|
```bash
|
||||||
|
sudo /bin/sh crochet.sh -c config.sh
|
||||||
|
```
|
||||||
|
On success an sdcard image will have been produced in the build directory, for example */opt/work/build/FreeBSD-armv7-12.0-GENERIC-333641-Clearfog.img*.
|
||||||
|
This image is a complete FreeBSD installation, without U-Boot installed.
|
||||||
|
|
||||||
|
### Create SD-Card
|
||||||
|
The previously created image can be written to an sdcard as is; assuming your SD-Card is available at /dev/sdX, write the image to it:
|
||||||
|
```bash
|
||||||
|
pv FreeBSD-armv7-12.0-GENERIC-333641-Clearfog.img | sudo tee /dev/sdX >/dev/null
|
||||||
|
```
|
||||||
|
|
||||||
|
## Boot It
|
||||||
|
In an ideal world U-Boot would already be installed in SPI flash, including the necessary patch for FreeBSD. If you happen to have such an ideal system, you may skip the next section
|
||||||
|
|
||||||
|
### Install U-Boot
|
||||||
|
For now, FreeBSD needs a patched version of U-Boot. You can find the patched source code [here](https://github.com/Artox/helios4_u-boot-marvell/tree/u-boot-2013.01-15t1-helios4). Please refer to [U-boot](/uboot) for build instructions.
|
||||||
|
|
||||||
|
The Boot-ROM expects to find U-Boot at 512 bytes into the sdcard. Assuming your SD-Card is available at /dev/sdX, write the u-boot binary to it using dd:
|
||||||
|
```bash
|
||||||
|
sudo dd bs=512 seek=1 conv=fsync if=u-boot-a38x-5-15-mmc.bin of=/dev/sdX
|
||||||
|
```
|
||||||
|
|
||||||
|
### Boot
|
||||||
|
Insert the sd-card into your device, connect a serial console and turn it on.
|
||||||
|
The U-Boot console will come up with a prompt:
|
||||||
|
```bash
|
||||||
|
Hit any key to stop autoboot: 3
|
||||||
|
```
|
||||||
|
Press a key to abort automatic boot, or wait till it fails to do a network boot.
|
||||||
|
Once it has dropped to a terminal prompt, indicated by *Marvell>>* at the start of the line, configure U-Boot to load the FreeBSD loader by default:
|
||||||
|
```bash
|
||||||
|
setenv fdt_addr_r 0x1000000
|
||||||
|
setenv loadaddr 0x2000000
|
||||||
|
setenv bootcmd 'fatload mmc 0:2 ${fdt_addr_r} armada-388-helios4.dtb; fatload mmc 0:2 ${loadaddr} ubldr.bin; go ${loadaddr}'
|
||||||
|
setenv bootdelay 1
|
||||||
|
saveenv
|
||||||
|
```
|
||||||
|
Beware: You probably have to paste these lines individually, or U-Boot may mess it up. You can set bootdelay to 0 if you want, that way you will never again get to the u-boot console unless you delete the FreeBSD loader.
|
||||||
|
|
||||||
|
Finally, type *boot*, or *reset*, or reset the board by pressing the button labeled U16 on the board.
|
||||||
|
This time, just sit back and watch as FreeBSD comes up.
|
||||||
|
|
||||||
|
### Default User
|
||||||
|
The FreeBSD image by crochet comes with an unlocked root account. This means you do not need to enter a password to log in as root.
