Question:  

What to do if a Martin P3 System Controller has bootup or OS issues? 

Answer:

If your P3 System controller experiences issues with booting up, issues with the P3 OS, or a software update failed, the P3 recovery wizard can resolve these problems.  The recovery wizard process reinstalls the P3 OS on the P3s hard drive (small memory card) instead of updating the software.

1. Power off P3-050/150/300 System Controller and remove lid.
2. Eject SD card (located underneath the bottom right of the raised DSP Board on P3-300, located at edge of mainboard on P3-050/150).
3. Insert the SD card into a card reader connected to a computer.
4. If needed, re-format the SD card (FAT32).
5. Download the ZIP file.
6. Extract following files from the ZIP file:
   1. dsp_card.fpga
   2. tingray_p3_150.fpga
