Newbie level 1
OpenJTAG is a great three-in-one (USB to JTAG, USB to serial port, on-line debugging) debuger. It can be used on both desktop and laptop even lack of serial or parallel ports, to debug ARM7, ARM9, Cortex-M3, XSCALE series CPU of nude board procedures, bootloader, the kernel, etc.
In the embedded development field, there are a lot of good debugging and simulation tools, such as Keil, IAR, Rowley Associates, and so on. Although they are easy to install, convenient to use, and provide powerful functions, but too expensive (several hundred dollars or more), even need to buy support hardware, eg. the J-Link, U-Link USB to JTAG the box, which is not a small sum of expenditure.
For the students or some engineers who has a limited budget for development , they can use free development tools, such as Eclipse, OpenOCD, then through some of the cheapest JTAG adapter (such as JTAG parallel port, etc.) will be able to reach the effect that close to or even beyond the above-mentioned commercial software.
Parallel Port JTAG rate is too low, in general rarely used to debug. This course use OpenJTAG converters, with Eclipse, OpenOCD, and other open source software, you can complete downloading, programming and debugging tasks and so on.
For s3c2410 and s3c2440 board, there is an programmer named flash, it can use OpenJTAG to burn the Nor flash or Nand flash directly.
