Automatically calculates the valid code checksum (at address 0x14) required by the bootloader to execute user code. Supported Microcontrollers

You might ask, "Why not just use a modern programmer?" Here’s where this tool shines:

In the golden age of ARM7 and Cortex-M0/M3 microcontrollers, NXP’s LPC2000 series (such as the LPC2103, LPC2138, and LPC2148) were workhorses of the industry. While modern IDEs like Keil or MCUXpresso dominate today’s workflow, there remains a dedicated niche of developers and retro-hardware enthusiasts who swear by a small, lightweight, and surprisingly effective tool: .

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.

If you're looking for more information or need to download the LPC2000 Flash Utility, I recommend visiting the NXP Semiconductors website or searching for the official documentation and software tools.

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.

To program your LPC2000 device using this utility, follow these general steps:

⭐⭐⭐⭐ (4/5) – Loses one star for its occasionally finicky auto-baud routine, but otherwise a timeless classic.
