| Intro |
| ===== |
| |
| This default configuration will allow you to start experimenting with |
| the buildroot environment for the MacchiatoBin board based on the |
| Marvell Armada 8040 SoC. Documentation for the board hardware and |
| software is available on the wiki at: http://wiki.macchiatobin.net |
| |
| This default configuration will bring up the board and allow access |
| through the serial console. |
| |
| How to build |
| ============ |
| |
| There are two build options: mainline support and vendor support. |
| |
| For the mainline BSP, we use: |
| - Linux v4.14.4 |
| - U-Boot v2017.11 |
| |
| For the vendor BSP, we use the sources available from Marvell Github |
| page at https://github.com/MarvellEmbeddedProcessors, which uses: |
| - Linux v4.4.52 |
| - U-Boot v2017.03 |
| |
| At the moment mainline support for the board is a work in progress. |
| Mainline kernel 4.14 with provided patches enables eth2 in 1Gb (RJ45 |
| connector J5) and eth0 in 10Gb (SFP connector J15). The vendor BSP |
| enables more hardware features out of the box, e.g. all the network |
| interfaces. |
| |
| To use the mainline BSP run the following commands: |
| |
| $ make solidrun_macchiatobin_mainline_defconfig |
| $ make |
| |
| To use the vendor BSP run the following commands: |
| |
| $ make solidrun_macchiatobin_marvell_defconfig |
| $ make |
| |
| How to write the SD card |
| ======================== |
| |
| Once the build process is finished you will have an image |
| called "sdcard.img" in the output/images/ directory. |
| |
| Copy the bootable "sdcard.img" onto an SD card with "dd": |
| |
| $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync |
| $ sudo sync |
| |
| How to boot the board |
| ===================== |
| |
| The MacchiatoBin board can be setup to load the bootloader from |
| different sources including eMMC, SPI flash, and SD-card. In order to |
| select boot from SD-card DIP switches SW1 and SW2 should be configured |
| as follows: |
| |
| SW2: 01110 |
| SW1: 1xxxx |
| |
| Insert the micro SDcard in the MacchiatoBin board and power it up. |
| The serial console is accessible at the micro-USB Type-B connector |
| marked CON9. The serial line settings are 115200 8N1. |
| |
| By default U-Boot will load its environment from the SPI flash. On the |
| first boot SPI flash may be empty or it may contain a legacy |
| environment incompatible with up-to-date mainline U-Boot and |
| kernel. Then the following commands can be used to boot the board: |
| |
| => ext4load mmc 1:1 0x01700000 /boot/uEnv-example.txt |
| => env import -t 0x01700000 $filesize |
| => boot |
| |
| The example environment from uEnv-example.txt can be written to |
| SPI flash using the following commands: |
| |
| => env default -f -a |
| => ext4load mmc 1:1 0x01700000 /boot/uEnv-example.txt |
| => env import -t 0x01700000 $filesize |
| => saveenv |
