Lpc2000 Flash Utility ((free))

The LPC2000 is a series of 32-bit ARM-based microcontrollers from NXP Semiconductors, known for their low power consumption, high performance, and rich peripheral set.

Effortlessly upload Intel HEX or binary files to the internal flash.

The interface is Spartan but functional: lpc2000 flash utility

Developed primarily by (and later adapted by others), this utility is the "swiss army knife" for programming the internal flash memory of LPC2000 devices via the UART0 bootloader.

⭐⭐⭐⭐ (4/5) – Loses one star for its occasionally finicky auto-baud routine, but otherwise a timeless classic. The LPC2000 is a series of 32-bit ARM-based

Click "Upload to Flash" to begin the process. Once finished, click "Execute" or manually reset the board to run your application. Modern Alternatives and Legacy Status

For anyone maintaining legacy LPC2000-based products or tinkering with vintage ARM development boards, is an essential, no-nonsense tool. It is not elegant, and it hasn't seen an update in over a decade, but it is reliable . It respects the engineer's time by doing one thing—writing flash via UART—and doing it well. ⭐⭐⭐⭐ (4/5) – Loses one star for its

It can automatically enter ISP mode by toggling the RTS (Reset) and DTR (P0.14) lines of a PC serial port.

At its core, the LPC2000 Flash Utility is a Windows-based GUI application (though it runs well under Linux via Wine) that communicates with the LPC’s built-in ISP (In-System Programming) bootloader. It bypasses the need for a JTAG/SWD debugger, requiring only a simple RS-232 serial port or a USB-to-UART converter.
