- 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.
