TPC recovery
The TPC has a built-in failsafe against firmware problems: it stores two versions of firmware. So if one copy of
the firmware fails to load, or becomes corrupted due to a loss of power during a firmware reload, the other can be
used instead. However, in the event that the TPC will not startup, there is a method to recover the TPC using the
memory card.
Please follow these instructions carefully:
1. Remove the memory card from the TPC and insert it into your computer
2. Wipe all files on the memory card (ensure you have made any necessary backups)
3. Locate the firmware directory in the Designer installation directory or app bundle*
4. Copy the file tpc.fw from the firmware directory to the memory card
5. On the memory card, rename the tpc.fw file to tpc.app
6. Reinsert the memory card into the TPC and restart the TPC. The TPC will boot, but will take longer to boot
than normal. Please be patient and wait for the Active LED to illuminate continuously
7. Connect to the TPC using Designer and
as normal
8. Remove the memory card from the TPC and insert it into your computer again
9. Delete the tpc.app file from the memory card
10. Reinsert the memory card into the TPC and restart the TPC.
* To locate the firmware directory in the app bundle on Mac OS X, please follow these steps:
1. Navigate to your "Applications" folder located on the the Hard Drive, typically named "Macintosh HD"
2. Locate the application called "Unison Mosaic Designer"
3. Right-click (or control-click) on it and choose "Show Package Contents" from the menu that appears
4. Now navigate to Contents/Resources/firmware to find the file tpc.fw.
