Infineon Memtool 4.9 is a verified, free-of-charge software tool designed for on-chip flash programming of Infineon microcontrollers. It is widely used by engineers for tasks such as erasing, programming, verifying, and protecting flash memory on a variety of Infineon device families. Overview of Infineon Memtool 4.9

"Target not found" on XC878 with USB BSL. Workaround: Pull P0.0 low during power-on reset. Verified fix.

With a J-Link EDU Mini on a TC275 board, Memtool 4.9 connected on the first attempt after selecting "J-Link / DAP" and setting interface speed to 4 MHz. No driver conflicts.

The memory viewer allows real-time editing of RAM/peripherals. Verified that changing a PWM compare register while the target runs works immediately – no need to halt core (though caution required).
