How to Use the Hardware Tool Emergency Boot Firmware Recovery Utility
|
|
Only use this utility to restore hardware tool boot firmware to its factory state. Use only if your hardware tool no longer functions on any machine. |
The debugger may need to be forced into recovery boot mode (reprogrammed) in rare situations; for example, if any of the following occurs when the debugger is connected to the computer:
• |
If the debugger has no LEDs lit. |
• |
If the LEDs are cyan in color. |
You must use MPLAB X IDE v4.15 or greater to use the emergency recovery utility.
Carefully follow the instructions found in MPLAB X IDE under the main menu option
Debug>Hardware Tool Emergency Boot Firmware Recovery.
