Infineon Memtool 4.9

Keep a copy of Memtool 4.9 on a dedicated Windows 7 virtual machine. Pair it with a quality USB-UART adapter (e.g., FT2232H). Learn its command-line switches for automation. And never, ever lose the installation file—it’s a lifeline for the industrial past that still powers our present. Have a specific Memtool 4.9 question? Check the included PDF manual ( Memtool_UserManual_V4.9.pdf ) after installation, or consult Infineon’s community forum. Happy flashing!

While Infineon pushes forward with AURIX and ARM-based controllers, the company has wisely left Memtool 4.9 in the public domain—a testament to the importance of backward compatibility. For engineers, it’s a lightweight, reliable, and eminently usable piece of software that has earned its place on every legacy embedded workbench. infineon memtool 4.9

Memtool.exe /device XC878 /com 3 /baud 115200 /erase /program firmware.hex /verify /exit This is invaluable for integrating into automated test racks. You can extract the factory bootloader code for analysis (though it’s read-protected on many devices). 3. EEPROM Emulation Handling Many XC800 derivatives emulate EEPROM using Flash sectors. Memtool 4.9 includes a dedicated “EEPROM Emulation” tab to write/read like a serial EEPROM. 4. Security Bit Recovery Warning If you enable high-security read protection, Memtool will warn that a full chip erase (via BSL) is required to reprogram—and that requires a special “BSL unlock sequence” using a specific key. Without the key, the chip becomes permanently locked. Memtool 4.9 handles this more transparently than later versions.
