The 'NGX ARM USB JTAG' is a compact USB to JTAG in-circuit debugger and programmer designed for ARM cores.It connects via USB to the host PC. The 'NGX ARM USB JTAG' provides a standard 20-pin JTAG interface as well as a standard RS232 port.

It is based on FTDI's popular FT2232 Dual USB UART/FIFO integrated circuit. The FT2232 has two devices integrated on it:

  • Channel A: USB to JTAG interface
  • Channel B: USB to SERIAL UART

JTAG Interface
It provides a standard ARM-compatible 20-pin JTAG interface. The JTAG interface enables access to the onchip debug module which is integrated into the ARM CPU. The debug module enables a programmer to debug the software on an embedded target system.

Serial UART
NGX ARM USB JTAG' serial port provides you with an independent functional "USB to RS-232" serial device. For Linux, the RS232 driver for the FT2232 is part of the main kernel tree and is provided in most standard Linux distributions. In Windows, you have to load the Windows driver for the FT2232. Once the driver is loaded, Windows will assign a virtual COM port to the serial port. It operates just like a standard COM port. You can use it on laptops or PC's that do not have a 9-pin legacy serial connector.
