SEGGER J-Link Debug Probe

J-Link_BASE.jpg

SEGGER's J-Link Debug Probes are USB-powered in-circuit programmer/debuggers supporting PIC32 devices through the JTAG interface.

Supported by MPLAB® X IDE (v2.15 and later), they provide cross-platform support (Windows, Linux, Mac OS X) and can be used to program or debug any PIC32 microcontroller using a JTAG or In-Circuit Serial Programming (ICSP) interface.

Typical Implementation

The J-Link Debug Probe, in conjunction with the Microchip adapter, presently supports the Microchip PIC32 product line through either the ICSP (2-wire) or JTAG (4-wire) interface. Below is an illustration of a typical implementation:

J-Link Debug Probe Configurations

SEGGER provides a wide variety of J-Link Debug Probes, but the configurations that support the PIC32 are summarized below:

1

J-Link PRO

The J-Link PRO has the most features and includes an Ethernet interface to enable remote debugging of the target. It also has a high-speed USB interface (3.0MB/sec) and has a maximum target (JTAG) interface speed of 50 MHz.

2

J-Link ULTRA+

The J-Link ULTRA+ is the J-Link PRO without the Ethernet interface.

3

J-Link BASE, and J-Link EDU

The J-Link BASE and J-Link EDU share the same hardware. These models have a full-speed USB interface (1.0MB/sec) and have a maximum target (JTAG) interface speed of 15 MHz.

  • J-Link BASE can provide unlimited software breakpoints (additional license fee required).
  • J-Link EDU is intended for non-commercial and educational purposes only. There is no licensing fee needed for the unlimited software breakpoints, but support is limited and available through the SEGGER forums only.
