Using J-Link

Installing the kernel mode driver

In order to use J-Link, the kernel mode USB driver jlink.sys needs to be installed. This is done by right clicking on the jlink.inf file and selecting "Install" from the context menu, or by connecting J-Link to a USB port of the Host PC and then referring to the inf file. An installation utility is to come up soon.

General JTAG info

J-link430 is shipped with a 14-pin JTAG connector.

JTAG interface connector signals for MSP430 CPUs:

Pin	Name	Function
1	TDO	JTAG data output from target CPU
2	VCC	Target supply voltage, may be delivered from J-Link
3	TDI	JTAG data input of target CPU
4	Vsense	Target voltage sense, used to measure target voltage
5	TMS	JTAG mode set input of target CPU
6	NC	not connected
7	TCK	JTAG clock signal to target CPU
8	TEST	Mode selection signal, used for some target CPUs
9	GND	Common ground
10	NC	not connected
11	RESET	Target CPU reset signal
12	NC	not connected
13	NC	not connected
14	NC	not connected

Target CPU board may be supplied from J-Link via pin 2.
If target board is supplied externally, pin 2 of interface (VCC) should not be connected.
VCC of target has to be connected to pin 4 (Vsense). This enables J-LINK 430 to sense the voltage level of interface signals and set its own outputs accordingly.

FAQs

Which MSP430 devices are supported ?

All flash-based MSP430 devices (F15x/F16x and devices with shared JTAG lines are included)

Is J-Link430 reliable ?

Definitely! J-Link has a built in microcontroller which provides accurate and reliable signals and timing.

Can J-Link blow JTAG fuses ?

Yes, J-Link430 can supply the 6.5V required to blow the fuses.

What does the green LED indicate ?

When connecting J-Link to the USB-bus, the LED flashes at a 10 Hz rate until the enumeration process has been completed. Enumeration is done by the PC and requires the J-Link driver. After that, the LED is lit when the J-Link is idle and off for short periods of time when J-Link is busy. If the LED is permanently off, there is typically no USB power.
