System Requirements & Installation

While previous Memtools ran on Windows XP/7, Memtool 49 New requires Windows 10 (64-bit) or Windows 11. It is optimized for ARM64 processors (like the Snapdragon X Elite) as well as traditional x86_64.

Installation Notes:

• Backup old configs: V4.9 stores settings in %APPDATA%\Infineon\Memtool\4.9 instead of the registry.
• Driver changes: The tool now uses the standard DAS (Debug Access Server) V8.0 or higher. If you use a MiniWiggler or DAP miniWiggler, ensure your drivers are updated from the Infineon Toolbox.
