eZ430-Chronos Software Projects
After invoking the wireless update (rFbSL), the watch tries to link to a listening RF access point and start
the update procedure. If the link is successful, the watch downloads the RAM-based updater into the RAM
of the CC430. Once finished, this software then tries to link again with the RF access point to download
the actual update image. If this link is successful, a mass flash erase is performed, which erases all the
main memory flash (0x8000 to 0xFFFF). The watch then starts to receive all of the data packets and
writes them to flash, checking if each word was written successfully. If the link is not successful, the watch
generates a reset to restart the user application. During the download of the update image, a percentage
indicator appears on the watch. When download is complete, "dOnE" is shown on the LCD, and a reset is
generated to start the new user application that has just been written to flash.
A detailed flow of the update software on the watch and the USB access point can be found in Figure 3-14
and Figure 3-15.
