DSP Compilation License Error

shuaweir — Tue, 18 Nov 2025 03:16:51 GMT

Hello,

I am attempting to follow the Getting Started guide for the board. I am getting the following licensing error when attempting to debug a DSP example application (3. Build, Run):

License checkout failed: No such feature exists.
Feature: XTENSA_XCC_TIE
License path:
C:/usr/xtensa/XtDevTools/install/tools/RJ-2025.5-win32/XtensaTools/Tools/lic/license.dat;
FlexNet Licensing error:-5,375

I have followed all previous steps in the Getting Start guide and attempted a reinstallation of the Xtensa Xplorer to no avail.

Thanks,

Josh

Note: NXP recommends version 10.1.11 of the Xtensa Xplorer IDE and tools for use with the RT600 DSP.
