USB Audio 2.0 with DFU disabled error

[bowerymarc]

usb audio 6.15.2rc1 - disable DFU, compiles. But gets this runtime error:

Code: Select all

tile[0] core[5]  (Suspended: Signal 'ET_ECALL' received. Description: [i]<path to>[/i]/sw_usb_audio-[sw]_6.15.2rc1/sc_usb_audio/module_usb_audio/main.xc:395:110: error: passing null argument to a non-null parameter.)	
	2 _Susb_audio_core_0.task.Endpoint0.2() main.xc:395 0x000130e0	
	1 __start_core()  0x0001647e	

and the line in question:

Code: Select all

           Endpoint0( c_xud_out[0], c_xud_in[0], c_aud_ctl, c_mix_ctl, c_clk_ctl, c_EANativeTransport_ctrl, dfuInterface);

(where main calls Endpoint0).

Now, endpoint0 is 'C' code, not 'XC' so the param dfuInterface is declared as 'unsigned', and it's being passed 'null'. I'm not sure exactly how to fix that properly.... via a cast or...?

I *think* this is fixed by changing the declaration in endpoint0.h to match that in endpoint0.c:

Code: Select all

extern "C" {
void Endpoint0(chanend c_ep0_out, chanend c_ep0_in, chanend c_audioCtrl,
        chanend ?c_mix_ctl,chanend ?c_clk_ctl, chanend ?c_EANativeTransport_ctr, CLIENT_INTERFACE(i_dfu, dfuInterface));
}
