This article describes specifics for the SiFive Arty FPGA Dev Kit.

Preparing for J-Link

Syntacore provides a reference FPGA bistream for the Digilent ARTY FPGA dev kit, which allows to implement a RISC-V core. The Digilent ARTY FPGA dev kit does not come with a standard debug connector but populates the debug JTAG signals on the JD connector of the eval board. Therefore, it needs to be manually wired in case J-Link shall be connected to it.

In the following, it is described how the pins of JD connector on the ARTY board needs to be wired to J-Link. All pins of the J-Link side refer to the standard 0.1" 20-pin connector of J-Link.

Wiring connection
Pin JD (ARTY) Pin J-Link Description
7 13 TDO
3 3 nTRST
4 9 TCK
8 5 TDI
10 7 TMS
9 15 nRESET
11 4 GND
12 1 VTref

Note: The pins on the JD connector are numbered as follows:

6 5 4 3 2 1
12 11 10 9 8 7

TBD Before continuing, make sure that you have J-Link software package Vxxx or later installed: Download J-Link software package

Minimum J-Link hardware requirements

Please note that RISC-V is not supported by older J-Link hardware models / revisions. For an overview about which models / revisions support RISC-V: List
