Flasher PRO is a programming tool for microcontrollers with on-chip or external Flash memory and ARM, RX or PPC core.
Flasher PRO is designed for programming flash targets with the J-Flash software or stand-alone.
In addition to that Flasher PRO has all of the J-Link functionality.
Flasher PRO connects via USB, Ethernet or via RS232 interface to a PC, running Microsoft Windows 2000, Windows XP, Windows 2003, Windows Vista, Windows 7 or Windows 8 and has a built-in 20-pin JTAG connector, which is compatible with the standard 20-pin connector defined by ARM.

Available software
In order to setup Flasher PRO for stand-alone operation, you need the J-Flash software from the J-Link software and documentation package.
Supported CPU cores / devices
Flasher PRO supports a wide range of cores/devices.
JTAG interface connection (20 pin)
There is a standard 20 pin connector defined by ARM. Flasher PRO has a built-in 20-pin JTAG connector, which is compatible with this standard.
JTAG interface connector signals:
| Pin | Signal | Type | Description |
|---|---|---|---|
| 1 | VTref | Input | This is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor. |
| 2 | Vsupply | NC | This pin is not connected in Flasher PRO. It is reserved for compatibility with other equipment. Connect to Vdd or leave open in target system. |
| 3 | nTRST | Output | JTAG Reset. Output from Flasher PRO to the Reset signal of the target JTAG port. Typically connected to nTRST of the target CPU. This pin is normally pulled HIGH on the target to avoid unintentional resets when there is no connection. |
| 5 | TDI | Output | JTAG data input of target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TDI on target CPU. |
| 7 | TMS | Output | JTAG mode set input of target CPU. This pin should be pulled up on the target. Typically connected to TMS on target CPU. |
| 9 | TCK | Output | JTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TCK on target CPU. |
| 11 | RTCK | Input | Return test clock signal from the target. Some targets must synchronize the JTAG inputs to internal clocks. To assist in meeting this requirement, you can use a returned, and retimed, TCK to dynamically control the TCK rate. Flasher PRO supports adaptive clocking, which waits for TCK changes to be echoed correctly before making further changes. Connect to RTCK if available, otherwise to GND. |
| 13 | TDO | Input | JTAG data output from target CPU. Typically connected to TDO on target CPU. |
| 15 | RESET | I/O | Target CPU reset signal. Typically connected to the RESET pin of the target CPU, which is typically called "nRST", "nRESET" or "RESET". |
| 17 | DBGRQ | NC | This pin is not connected in Flasher PRO. It is reserved for compatibility with other equipment to be used as a debug request signal to the target system. Typically connected to DBGRQ if available, otherwise left open. |
| 19 | 5V-Target supply | Output | This pin can be used to supply power to the target hardware. |
All pins marked NC are not connected inside Flasher PRO. Any signal can be applied here; Flasher PRO will simply ignore such a signal.
Pins 4, 6, 8, 10, 12, 14, 16, 18, 20 are GND pins connected to GND in Flasher PRO. They should also be connected to GND in the target system.
Pin 2 is not connected inside Flasher PRO. A lot of targets have pin 1 and pin 2 connected. Some targets use pin 2 instead of pin 1 to supply VCC. These targets will not work with Flasher PRO, unless Pin 1 and Pin 2 are connected on the target's JTAG connector.
Pin 3 (TRST) should be connected to target CPUs TRST pin (sometimes called NTRST). Flasher PRO will also work if this pin is not connected, but you may experience some limitations when debugging. TRST should be separate from the CPU Reset (pin 15)
Pin 11 (RTCK) should be connected to RTCK if available, otherwise to GND.
Pin 19 (5V-Target supply) of the connector can be used to supply power to the target hardware. Supply volatage is 5V, max. current is 300mA. The output current is monitored and protected agains overload and short-circuit.
Power can be controlled via the J-Link commander. The following commands are available to control power:
| Command | Explanation |
|---|---|
| power on | Switch target power on |
| power off | Switch target power off |
| power on perm | Set target power supply default to "on" |
| power off perm | Set target power supply default to "off" |

JTAG Speed
There are basically three types of speed settings:
-
Fixed JTAG speed
-
Automatic JTAG speed
-
Adaptive clocking
Fixed JTAG speed
The target is clocked at a fixed clock speed. The maximum JTAG speed the target can handle depends on the target itself. In general ARM cores without JTAG synchronization logic (such as ARM7-TDMI) can handle JTAG speeds up to the CPU speed, ARM cores with JTAG synchronization logic (such as ARM7-TDMI-S, ARM946E-S, ARM966EJ-S) can handle JTAG speeds up to 1/6 of the CPU speed. JTAG speeds of more than 10 MHz are not recommended.
Automatic JTAG speed
Selects the maximum JTAG speed handled by the TAP controller.
NOTE:
On ARM cores without synchronization logic, this may not work reliably, since the CPU core may be clocked slower than the maximum JTAG speed.
Adaptive clocking
If the target provides the RTCK signal, select the adaptive clocking function to synchronize the clock to the processor clock outside the core. This ensures there are no synchronization problems over the JTAG interface.
NOTE:
If you use the adaptive clocking feature, transmission delays, gate delays, and synchronization requirements result in a lower maximum clock frequency than with non-adaptive clocking. Do not use adaptive clocking unless it is required by the hardware design.
