H-JTAG is a free debugging proxy software that supports ARM7 and ARM9 processors, thumb and arm instruction sets, little-endian and big-endian, semihosting, and flash device programming.
This manual explains how to set up the H-JTAG software, select target devices, and perform JTAG operations such as flashing, resetting and scripting. It includes detailed screens for File Operations, Flasher, Script Settings and Target configuration.
The guide also covers troubleshooting tips, port configuration, endianness selection and supported processor families, helping users quickly get the H-JTAG tool working with their hardware.
| Supported CPUs | ARM7, ARM9, ARM9E, ARM9EJ |
|---|---|
| Supported Operating Systems | Windows 9.x/NT/2000/XP |
