This article describes specifics for the Syntacore Arty SCR1 SDK.

Minimum J-Link hardware requirements

Please note that RISC-V is not supported by older J-Link hardware models / revisions. Overview about which models / revisions support RISC-V

Preparing for J-Link

The Syntacore Arty SCR1 SDK does not come with a standard debug connector but populates the debug JTAG signals on a custom connector. 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 connector JD 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
3 3 nTRST
4 9 TCK
7 13 TDO
8 5 TDI
9 15 nRESET
10 7 TMS
11 4 GND
12 1 VCC/VTref

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

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