[Buildroot] [PATCH 1/1] board: add support for Acme Systems Acqua A5
Edgar Bonet

Mon Mar 22 17:14:24 UTC 2021
The Acqua A5 is a system on module based on the Microchip SAMA5D31 SoC:
https://www.acmesystems.it/acqua
It is available in both 256 MiB and 512 MiB versions, hence the two
defconfig files. These configs build microSD card images with:
- AT91Bootstrap 3
- Linux 5.4.107
- default buildroot packages (uClibc, Busybox)
The device tree blob comes from Acme Systems:
https://github.com/AcmeSystems/dts-archive
It is licensed under GPLv2 or later.

+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.
