- 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 v4.19.2
- - U-Boot v2018.11
- For the vendor BSP, we use the sources available from Marvell Github
- page at https://github.com/MarvellEmbeddedProcessors, which uses:
- - Linux v4.4.120
- - U-Boot v2018.03
- At the moment mainline support for the board is a work in
- progress. Mainline kernel 4.19 enables eth2 in 1Gb (RJ45 connector J5),
- copper 10Gb interfaces, and automatic configuration of select SFP
- modules on the SFP cages. The vendor BSP enables more hardware features
- out of the box, but lacks support for SFP detection and automatic
- configuration.
- 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.
- On Rev 1.2 board to select boot from SD-card the DIP switches
- SW1 and SW2 should be configured as follows:
- SW2: 01110
- SW1: 1xxxx
- The upcoming Rev 1.3 board will have a single pins header J1 instead
- of the SW1/2 DIP switches. To boot from SD-card the setting of J1
- jumpers should match the DIP switches of Rev v1.2 board
- from left to right:
- J1: 011101xxxx
- 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.
- Note: the following text only applies to the vendor BSP from
- solidrun_macchiatobin_marvell_defconfig.
- By default Marvell provided 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 that prevents proper boot. 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
