H-JTAG One-Click Flashing of Embedded Systems User Manual

About this manual

The guide walks users through preparing a target board, connecting the H-JTAG USB emulator, and launching the H-JTAG software. It then shows how to configure the H‑FLASHer utility with the appropriate example configuration files for the specific hardware platform.

Subsequent sections describe dumping the existing NAND flash image, creating a single binary file, and using H‑FLASHer to program the flash in a single step. An optional production mode automates the programming process for high‑volume manufacturing. This manual is written in Chinese.

Frequently asked questions

How do I configure H‑FLASHer for a specific board?

Run the H‑FLASHer program, load the appropriate *.HFC configuration file from the "H‑JTAG\HFC Examples" folder, or create a custom configuration if none is provided.

What is the production mode in H‑FLASHer?

Production mode enables automatic flash programming when a new JTAG connection is detected, eliminating the need for manual start/stop actions.

How can I dump only the used portion of NAND flash?

Set the dump range to cover only the blocks/pages that contain the bootloader, kernel and filesystem (e.g., Block‑0/Page‑0 to Block‑3850/Page‑31) instead of the entire chip.
