Hi,
MCUXpresso config tool does not support DSP project clone. We have to import/export the project and do some modification.
1. Export and import a demo project. This is easy.
2.Copy SDK_2.8.2_EVK-MIMXRT685\devices\MIMXRT685S\xtensa to your workspace, default directory is C:\usr\xtensa\Xplorer-8.0.10-workspaces\workspace. SDK 2.8.2 forget to include this directory, so I attach it here.
3. Open Project->Build Properties. These two midifi all the items.


4. Modify the MakeFile.include
line 10: xt-objcopy ${xt_sysargs} -O binary ${xt_project} ../../../binary/dsp_data_$(build_target).bin \
line 36: xt-objcopy ${xt_sysargs} -O binary ${xt_project} ../../../binary/dsp_data_$(build_target).bin \
line 62: xt-objcopy ${xt_sysargs} -O binary ${xt_project} ../../../binary/dsp_ncache_$(build_target).bin \
