Getting started with Acqua A5 and Berta dev boards

This article explains how to get started with Acqua A5 module using one of the Berta dev boards available

What do you need to start ?

Acqua A5 is designed to be used on a carrier board. The following carriers are available from the Acme Systems eStore:

If you are using a custom designed board you need at least the following parts:

Insert the Acqua A5 on the BERTA-A5-EXT carrier board:

Insert the bootable microSD inside the Acqua A5 microSD holder:

Insert the DPI adapter:

or alternatively the USB-3V-SER adapter:

Set the serial terminal configuration at: 115200.N,8,1 with no acknowledge

This is the debug port pinout

| 1   | 2   | 3   | 4   | 5  | 6   |

Plug the 5 volt power supply and check the bootstrap messages on the serial terminal:

In this phase is not so important to configure the dip switch near the mini USB connector so you can leave it in the default configuration:

This is the dip switch meaning:

1	2	3	4	Function
ON	ON	OFF	OFF	USB A lines on J8 microUSB port. In this way it is possible to access to RomBOOT code using SAM-BA or use the Linux Kernel USB gadget drivers
OFF	OFF	ON	ON	USB A lines on WiFi module
