Hello,
I am new to XMOS and have teething troubles trying lib_dsp. I created a workspace, imported lib_dsp and app_fft into it. Built app_fft successfully. Then I changed the target in the makefile to "USB Audio 2.0 Multichannel Board" (which I have) and the build fails with a whole bunch of "unknown opcode" errors. What did I miss?
Thanks!

I just tested and it works fine for me. What's odd though, is I do not have "USB Audio 2.0 Multichannel Board" as a target option. I choose "XE216-512-TQ128-C20" as the target (that's the silicon on the board). Also, I'm building the "complex" version (but I've used the others in the past without problem).

Thanks - entering the silicon as target worked for both programs. Strange that you do not see the USB MC board. Attached is a screenshot for your benefit.
I did forget to mention I am doing this on Linux Mint...not sure if the build failure had something to do with that.
