Syntacore SCR1 SDK Arty
This article describes specifics for the Syntacore SCR1 Arty SDK.
Minimum J-Link hardware requirements
Please note that a current J-Link model is needed for RISC-V support: Overview
Maximum JTAG speed
When debugging on the Syntacore SCR1 Arty SDK, the max. JTAG speed that can be used is 1 MHz. Speeds above 1 MHz will result in unstable operation of the debug interface on the device. This is not a limitation of J-Link but of the Syntacore SCR1
Preparing for J-Link
The Syntacore SCR1 Arty 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.
