Hardware
This document describes the Subwoofer application in ADK 3.0. The Subwoofer application is suitable for use on
CSR8670 or BlueCore5-Multimedia devices.
These use either the CSR Bluetooth example CNS10001v4 (CSR8670) or DEV-PC-1645 (BlueCore5-Multimedia)
design boards.
Notes:
A DEV-PC-1309 interface board and suitable SPI interface, such as a CSR 132 USB-SPI converter, is required
to program and debug both BlueCore5-Multimedia and CSR8670 devices.
2.1.1. Backing Up the Development Board
Before flashing the application to the hardware CSR recommends clearing all the PS Keys from the development
board. This places the board in to a known good state.
All tools are available in the
[ADK]\tools\bin
sub directory. Alternatively, tools with a GUI, e.g.
PSTool
and
BlueFlash
,
can be accessed from the Windows
Start
menu under
ADK\Tools
.
Note:
Read the values in the following PS Keys using
PSTool
and record the values so that they can be restored later:
PSKEY_BD_ADDR
PSKEY_ANA_FTRIM (BlueCore5-Multimedia)
PSKEY_ANA_FTRIM_OFFSET (CSR8670)
PSKEY_CHARGER_CURRENT
PSKEY_CHARGER_TRIM
To clear the board’s PS Keys using
BlueFlash
:
1.
Click
Stop Processor
and select
Flash Erase
2.
Check the
Erase Persistent Store
box and then select
OK
.
3.
Exit
BlueFlash
.
The application is then ready to be flashed from the xIDE development environment onto the development board.
