Error With Optimization - app_usb_aud_xk_216_mc

[u12018202]

Hi all

I am currently running the app_usb_aud_xk_216_mc project on a the xCore 200 MC Audio Platform. I have run the program as it comes and it works perfectly. I would like manipulate valus read into "unsigned sample" within the audio.xc.

As the program is set up to run with -O3 optimisation in the Makefile which causes the sample vector to be "optimised out" in debug mode. I would very much like to see this optimised out values and thus I have swithed the mode to the unoptimised "OO" setting. 

However when I try to run program I get the following errors in the console:

Creating app_usb_aud_xk_216_mc_2i16o16xxxxx_tdm8.xe

xmake: *** [bin/2i16o16xxxxx_tdm8/app_usb_aud_xk_216_mc_2i16o16xxxxx_tdm8.xe] Error 2
 
Once again the stock code available has been unaltered besides the optimisation level.
I am having difficulty overcoming this. Any help would be appreciated

Hi, have you tried a clean build after changing the optimisation to -O0?

Hello,

 

Don't know if you found a solution. I had the same link error a couple of days ago and to fix it I had to add:

extern XUD_Result_t XUD_SetReady_In(XUD_ep ep, unsigned char buffer[], int len);

in file usb_buffer.xc.
 
And:
 
extern XUD_Result_t XUD_SetReady_InPtr(XUD_ep ep, unsigned addr, int len);
extern int XUD_SetReady_OutPtr(XUD_ep ep, unsigned addr);

 
in file decouple.xc.
