Cannot program psoc5 when selecting "Debug Select GPIO" with Psoc Creator

[taherrera]

Hello,

I need to use pins 11 and 12 as GPIO in the CY8C5868LTI-LP039 MCU. So I disabled SWD debug pins by selecting GPIO as debug in Psoc Creator.

Now I cant reflash the device using Psoc Creator (Port Acquire Failed), and the only way to reprogram the device is by using Psoc Programmer, both Reset and Power Cycle work.

If I re-select "Debug Select SWD", I can reprogram the device with Psoc Creator.

Is this a known issue or is it possible there is some other hardware problem ?

Hi, 
Is the pin XRES connect to your kit prog ? 

The VDDD, VDDIO1 of PSoC 5 should be at the same voltage level as Host VDD (KitProg3). 
Refer to this document on page 63. 


Warm regards,

@taherrera ,

When I set my SWD pins to GPIO in a project. it requires me to reacquire the SWD port in PSoC Creator.

Here is a screenshot of the "Select Debug Target" when I select the "Program Part" icon.

I then select the "Port Acquire" button.  This forces a reset of the XRES pin to make the SWD pins become SWD pins again.

Once the target PSoC appears, I select the "OK/Connect" button.
