Workaround 1

The Curiosity Nano debugger can be re-provisioned by the end-user with updated masks using a

binary utility.

Procedure:

1. Navigate to github.com/microchip-pic-avr-tools/debuggerconfigfix and download the

debuggerconfigfix utility for the appropriate operating system.

2. Connect the Curiosity Nano kit to the host PC and reprovision the debugger by opening a

command-line/terminal and executing the binary

debuggerconfigfix.exe

3. Check the console output for success indication:

*** Debugger configuration SUCCESS ***

4. Unplug the Curiosity Nano kit and plug it in again for the new mask to take effect.

Workaround 2

The Curiosity Nano debugger can be re-provisioned by the end-user with updated masks using a

Python-based utility.

Requirements:

• Python 3.8 or later installed

Procedure:

1. Install the pydebuggerconfig Python package using:

pip install pydebuggerconfig

Note: If the pydebuggerconfig package is already installed, update it to version 3.11 or newer.

2. Connect the Curiosity Nano kit to the host PC and reprovision the debugger using

pydebuggerconfig write -d AVR16EB32-device-blob.xml

3. Unplug the Curiosity Nano kit and plug it in again for the new mask to take effect.

Workaround 3

When writes to reserved locations are skipped by the debugger, this issue occurs, and the

verification fails as unexpected values read back. You can avoid verification errors by providing

the reserved fuse values already in the MCU in the project being programmed.

For example, in a project, a structure like this specifies the fuse values:

FUSES =

{

...

};

The values already programmed in reserved locations can be added to this structure (in this case

0xFF) by adding:

.reserved_1 = {0xFF, 0xFF},

.reserved_2 = 0xFF,

During verification, the specified values will match the values already programmed, and no

verification issues will be seen.
