configs/globalscale_espressobin: new defconfig
Basic support for the Marvell ESPRESSObin, by Globalscale Technologies. http://espressobin.net The kernel config has been extended with a fragment to enable switchcore support, DSA drivers, and VLAN filtering in the bridge. To make use of this you need a custom libnl based application, or the iproute2 suite rather than the brctl tools, which don't support the VLAN filtering.

Marvell ESPRESSObin
|
||||
===================
|
||||
|
||||
This default configuration allows you to quickly get up and running with
|
||||
the Marvell ESPRESSObin board by Globalscale Technologies Inc.
|
||||
|
||||
The ESPRESSObin is based on the Marvell Armada 88F3720 SoC, coupled with
|
||||
a Marvell 88E6341 switch core "Topaz", with three exposed gigabit ports.

||||

Fig 1: Overview of board
|
||||
|
||||
Notice difference in Ethernet port layout compared to the Globalscale
|
||||
docs. They order the ports; LAN2, LAN1, WAN (left to right in figure
|
||||
above). For more information, see http://espressobin.net
|
||||
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
$ make globalscale_espressobin_defconfig
|
||||
$ make
|
||||
|
||||
This generates the kernel image, the devicetree binary, the rootfs as a
|
||||
tar.gz, and a filesystem image containing everything.
|
||||
|
||||
All build artifacts are located in `output/images/`
|
||||
|
||||
|
||||
Booting
|
||||
-------
|
||||
|
||||
To boot, you need a UART connection, using the on-board micro USB port
|
||||
set to 115200 8N1.
|
||||
|
||||
By default, the ESPRESSObin comes with a pre-flashed U-Boot set up to
|
||||
load the kernel, device-tree and rootfs from SPI NOR flash. The board
|
||||
jumpers can be changed to boot from different sources, see the quick
|
||||
start guide for each board revision for details:
|
||||
|
||||
- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V5/
|
||||
- ftp://downloads.globalscaletechnologies.com/Downloads/Espressobin/ESPRESSObin%20V7/
|
||||
|
||||
Note: the v5, and earlier, cannot boot from sdcard, so you have to set
|
||||
up the factory U-Boot to boot into Buildroot:
|
||||
|
||||
1. Flash rootfs image to sdcard drive, your `of=` device may differ:
|
||||
|
||||
$ sudo dd if=output/images/sdcard.img of=/dev/mmcblk0 bs=1M
|
||||
$ sync
|
||||
|
||||
2. Boot board from SPI NOR, interrupt boot by pressing any key ...
|
||||
3. Check with `printenv` that the default setup is OK, otherwise ensure
|
||||
the following are set, and define `bootcmd` for automatic boot:
|
||||
|
||||
> setenv kernel_addr 0x5000000
|
||||
> setenv fdt_addr 0x1800000
|
||||
> setenv fdt_name boot/armada-3720-espressobin.dtb
|
||||
> setenv console console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000
|
||||
> setenv bootcmd 'mmc dev 0; ext4load mmc 0:1 $kernel_addr $image_name;ext4load mmc 0:1 $fdt_addr $fdt_name;setenv bootargs $console root=/dev/mmcblk0p1 rw rootwait; booti $kernel_addr - $fdt_addr'
|
||||
|
||||
4. Call the boot command, or `reset` the board to start:
|
||||
|
||||
> run bootcmd
|
||||
|
||||
|
||||
Networking
|
||||
----------
|
||||
|
||||
To enable Ethernet networking, load the `mv88e6xxx` kernel module, and
|
||||
bring up each respective interface needed:
|
||||
|
||||
# modprobe mv88e6xxx
|
||||
# ifconfig wan up
|
||||
|
||||
A more advanced scenario is setting up switching between the ports using
|
||||
the Linux bridge. The kernel switchdev layer, and DSA driver, ensure
|
||||
switch functions are "offloaded" to the HW switch, i.e., all traffic
|
||||
between LAN ports never reach the CPU. For this you need the iproute2
|
||||
suite of tools.
