=====
|
|
|
|
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
|
|
============
|
|
|
|
Default configuration provides the following BSP versions:
|
|
- Linux v5.10.5
|
|
- U-Boot v2020.10
|
|
- ATF v2.4
|
|
|
|
To build images run the following commands:
|
|
|
|
$ make solidrun_macchiatobin_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.
|
|
|
|
U-Boot environment
|
|
==================
|
|
|
|
By default current configuration provides U-Boot that keeps environment
|
|
in SD/eMMC. However, if needed, u-boot-fragment.config can be tweaked
|
|
so that U-Boot will keep environment in SPI flash. On the first boot
|
|
SPI flash may be empty or it may contain a stale 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
|
