Dose anyone know, how to use P1[3](SWO) as GPIO with SWD?

[LeYu_281131]

As I know PSoC3 just use 2pins, P1[0] and P1[1] with SWD.

   

So, I disconnect P1[3] with debugger and disable SWV option.

   

but It works perfectly with compile and debug.

   

I'm sure the SWV(P1[3])  does not working now.

   

so, i was put a rx_pin at P1[3] and try to compile.

   

but PSoC Creater shows me below message.

   

Cannot place "Rx_1(0)" at "[Chip=0][IOP=(1)][IoId=(3)]" because the location is reserved by "SWD debug".

   

It is connect in hardware?

   

or just Software problem?

   

if anyone know, please reply.

   

Thank you.

The Pin P1[3] was reserved for specific purpose in older revisions of PSoC3 silicon. Hence creator was giving this warning. A newer version of Creator will be available soon which will have fix for the issue you have mentioned.
