14 FLASH LOADER INSTRUCTIONS.
The CASIRA Bluetooth Development kit is pre-configured with firmware on the
BlueCore
TM
chips that allows data and voice communication. When new firmware
upgrades become available from CSR the user will need to install and use the Flash
loader Program supplied with the system to upload the new firmware into the
Systems Units.
The Flash loader program “CSR_Flashloader” allows the user to download to the
evaluation kit Flash memory. The first task of the program is to load into internal
RAM a small boot loader that takes data from the UART and stores the data to the
external Flash memory. Once the Flash upload is complete and verified the boot
loader in RAM will be over written by the executed program.
