Debugging with OpellaXD
ARC GNU IDE documentation has been moved to https://embarc.org/toolchain/ide/debugging-with-opellaxd.html
It is expected here that you have already built your application and created a debug configuration for it. About how to do it you can read on the following pages:
Note: Opella-XD has some problems, see Known issues section [here] (https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/wiki/AXS-SDP-and-Ashling-GDB-Server#known-issues).
Board should be configured mostly the same way as for OpenOCD, see here.
However, it might be needed to change some jumper settings comparing to OpenOCD. For example, to use Opella-XD with EM Starter Kit 1.1 you should set J8 jumper. Refer to the User Guide of EM Starter Kit or AXC00x CPU Card you are using.
Opella-XD on debugger tab
In this tab you should specify paths to your ashling executable file and two XML
files. Both these files you can find here.
In the Ashling XML File field you should choose one of arc600-cpu.xml,
arc700-cpu.xml, arc-em-cpu.xml and arc-hs-cpu.xml. In the
Target description XML file should be path to opella-YOUR_CPU-tdesc.xml.
JTAG frequency should be set to 7 MHz for EM Starter Kit 2.0 and 2.1. For EM Starter Kit 2.2 select 5 MHZ. For other hardware development systems leave 10 MHz.
Note that if you are using Opella-XD, you can not specify the core to debug, so you will be able to debug your application only if you have just one core in your JTAG chain.
To debug an application using OpenOCD, press Debug button of IDE and confirm switching to Debug Perspective.
