I'm assuming the part number is CY8C6137-BZI-F54. I'm using PSoC Creator 4.3 and I'm able to assign digital output pins to P0.0 and P0.1.
Check if you have enabled WCO in the clocks configurator. If WCO is enabled, then P0.0 and P0.1 are reserved pins and should be connected to an external WCO crystal. They can not be used as a GPIO. Please confirm.
If this doesn't solve your issue, please share the project to debug the issue further.
Thanks a lot, this worked.
Actually I new to PSOC6 and so I had no idea regarding this.
