3.6.4.4.2 eZ430-Chronos Watch Update

The update of the eZ430-Chronos watch needs to be done in two stages. First, the wireless updater

needs to be written to the BSL area of the flash memory of the CC430. Afterwards, the main application

must be loaded onto the watch. The easiest and fasted way is using BM innovations' Firmware Update

Tool. It writes the wireless updater into the BSL memory of the watch and programs the corresponding

sports watch firmware according to the latest eZ430-Chronos software release (recommended).

Alternatively, wireless updater may be loaded onto the watch using the included IAR Embedded

Workbench (free KickStart version is sufficient). Moreover, the .txt image may be written to the device by

using 3rd party tools such as the free FET-Pro430 Lite software from Elprotronic.
