CoiNel ARM USB JTAG

Description

OVERVIEW

CoiNel ARM-USB-JTAG is Compact USB JTAG in-circuit debugger and programmer designed for ARM cores.

It is based on FT2232 (Dual USB UART converter). The FT2232 has two devices integrated on it:

Channel A: USB to JTAG interface.
Channel B: USB to SERIAL UART (TTL Logic Out)

JTAG Interface.

A standard 20 pin JTAG interface connector option is provided which can be used to connect the target board to debug/programming. The CoiNel ARM USB JTAG can be used to access the on-chip debug module integrated in the ARM Chip. The programmer can debug the firmware in real time using the module.

The PinOut of JTAG Interface is shown in the below image

USB to Serial Interface.

The board also has an option for USB to Serial Converter(TTL Logic).

The pinout details of Serial PinOut is as below

You would need the driver to be installed for FT2232 to use the USB to Serial module.

Note: The power source for USB to RS232 is via Target supply.

For Linux, the driver is a part of the kernel.

For Windows, the driver needs to be installed after which this module can be used as a virtual COM port.
