FAQs
22. The wireless update procedure always returns an error while downloading to flash.
Make sure that the file you are trying to download does not include data outside the main flash
boundaries, which are 0x8000 to 0xFFFF. This protection mechanism avoids writing of data to
non-existent or restricted addresses. Try to download one of the original example project’s .txt files,
which are available for Windows in C:\Program Files\Texas
Instruments\eZ430-Chronos\Recovery\eZ430-Chronos Watch\Applications and for Linux in
/home/<user name>/Texas Instruments/eZ430-Chronos/Recovery/eZ430-Chronos Watch/Applications.
If the update still does not work, the RAM-based updater may be corrupted; see the next question.
23. The wireless update always returns an error while downloading to RAM.
Make sure that the file named "ram_based_updater.txt", which is located on the working directory of
your Control Center or Data Logger GUI has not been changed. If so, reinstall the eZ430-Chronos
Software to restore the original file.
24. I get an error message right after I start the wireless update on the PC.
Failed to start Wireless Update.
Check if the RF access point contains right software version. Kits older than 04/2010 (date code can
be found on bottom of the eZ430-Chronos box) require a manual update as described in Section 3.6.4.
25. Activating the rFbSL mode on the watch always results in a rest.
This is normal. Whenever the wireless update was activated on the watch, it returns to the main
application with a reset, regardless if an update was performed or not. Time, data, alarm, and other
RAM-based data is lost. For details, see Section 3.6.4.
26. The buzzer doesn't work when the watch is not inside the housing. What's wrong?
This is normal as the buzzer is located on the metal back of the watch. It is only connected to the
watch module when the back is mounted on the watch.
