Acme Systems Acqua A5
|
||||
|
||||
Intro
|
||||
=====
|
||||
|
||||
The Acqua A5 is a system on module based on the Microchip SAMA5D31 SoC:
|
||||
|
||||
https://www.acmesystems.it/acqua
|
||||
|
||||
The files here support configurations that build a microSD image for a
|
||||
minimal system that can be accessed through the serial console. You will
|
||||
need an USB-to-serial interface in order to access that console from
|
||||
your computer:
|
||||
|
||||
https://www.acmesystems.it/DPI
|
||||
|
||||
How to build the image
|
||||
======================
|
||||
|
||||
If you have an Acqua module with 256 MiB of RAM, type:
|
||||
|
||||
$ make acmesystems_acqua_a5_256mb_defconfig
|
||||
|
||||
If you have the 512 MiB version, type instead:
|
||||
|
||||
$ make acmesystems_acqua_a5_512mb_defconfig
|
||||
|
||||
You can optionally tweak the configuration and add packages by typing:
|
||||
|
||||
$ make menuconfig
|
||||
|
||||
Then, proceed with the build:
|
||||
|
||||
$ make
|
||||
|
||||
How to write the microSD card
|
||||
=============================
|
||||
|
||||
The system image is the file "sdcard.img" in the "output/images"
|
||||
directory. Write it to the card by invoking:
|
||||
|
||||
$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M
|
||||
|
||||
where `sdX' is the block device representing the microSD card.

Build instructions
|
||||
==================
|
||||
|
||||
To build an image for the Aria G25 choose the configuration
|
||||
corresponding to the Aria variant.
|
||||
|
||||
For 128MB RAM variant type:
|
||||
|
||||
$ make acmesystems_aria_g25_128mb_defconfig
|
||||
|
||||
else for 256MB RAM variant type:
|
||||
|
||||
$ make acmesystems_aria_g25_256mb_defconfig
|
||||
|
||||
To customize the configuration choosed type:
|
||||
|
||||
$ make menuconfig
|
||||
|
||||
When you are ready to start building Buildroot type:
|
||||
|
||||
$ make
|
||||
|
||||
How to write the microSD card
|
||||
=============================
|
||||
|
||||
Once the build process is finished you will have an image called
|
||||
"sdcard.img" in the output/images/ directory.
|
||||
|
||||
Write the bootable SD card image "sdcard.img" onto an SD card with
|
||||
"dd" command:
|
||||
|
||||
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
|
||||
|
||||
Assuming your Aria G25 baseboard has a MicroSD socket, for example
|
||||
with the Terra baseboard, insert the microSD card into the baseboard
|
||||
slot and power it.
|
||||
|
||||
To get the kernel log messages you can use a DPI cable
|
||||
(http://www.acmesystems.it/DPI)
|
||||
|
||||
You can find additional informations, tutorials and a very
|
||||
comprehensive documentation on http://www.acmesystems.it/aria.
