Xtensa Debugger Daemon Not working in Linux

abdob — Wed, 14 Dec 2022 18:26:49 GMT

I have the IMXRT685 board and I am following the Getting Started with Xplorer for EVK-MIMXRT685, Rev. 2.12.0, 01 June 2022 Guide.

On section 2.5 Install Xtensa On Chip Debugger Daemon I install xt-ocd-14.08-linux64-installer from the path /opt/xtensa/XtDevTools/downloads/RI-2021.8/tools/.

The latest versions of the J-link drivers are installed (7.82 and 7.66b which was the latest as of 01 June 2022).

I am able to perform section 2.6 Program LPC-Link2 with SEGGEER J-Link, extract the SN and update the topology.xml file.

However later in Section 5.2 Build and Debug DSP Application step 2, Launch xt-ocd debugging server.

I cd into /opt/Tensilica/xocd-14.08 and run ./xt-ocd -c topology.xml

I get:

Loading module "gdbstub" v2.0.0.12
ERROR: Error loading module jlink:

On section 2.5 it states "For Linux: When installing xt-ocd on Linux, ensure that the symlink is manually added to the installed J-Link driver: ln -s <jlink-install-dir>libjlinkarm.so.6 <xocd-install-dir>/modules/libjlinkarm.so.6"

However in the jlink drivers file only the file libjlinkarm.so.7 is present, not the libjlink.arm.so.6

If I try to copy the libjlinkarm.so.6 file from the jlink driver directory to the xocd-14.08/modules directory as liblinkarm.so.7 and run it from the modules directory like this:

../xt-ocd -c ../topology.xml

I get this:

So whats the issue here, seems like a dependency issue since the wrong library name was installed?

Has this been tested with linux? I noticed the instructions have "./xt-ocd.exe" on the linux section instead of "./xt-ocd"

I found a jlink drivers version 6.96 (similar to the video) tutorial, that works.
