I am trying to use the CY8CKIT-062 - BLE to have UART on pins 8.0 and pins 8.1. So I took the simple UART printf example code and change the TX pin to be 8.1 in the TopDesign.cysch and rebuilt it. Once I rebuilt and programmed the part pin 8.1 never toggles or changes. Does anyone know if this is a known bug?
Thanks

For different board revision, silicon ES version is different i think. For production, you won't get the ES silicon.
Did you solder R100 on your board when you monitor signal on P8[1]? This resister is not load by default.

I think maybe the PDL version you used is not compatible with the 062-BLE board. If the board revision is 11, please change to use PDL 3.0.1 or PDL 3.0.4.

Is this because of a silicon change between boards? If so how do we know which to use in production?

Changing the PDL version did not fix the problem.

I have tried a rev13 board with 3.0.1 and it does not work. Rev11 board with 3.0.1 does not work either.

I tried turning 8.1 into a GPIO and drive high and it does not work either.
Is there something with the cap sense pins that need to be reconfigured.

Thanks,
I was not use to "No Load" as meaning not populated and since the resistor had a value I assumed it was populated. I asked another engineer and he said he had found the same problems and assumed he fried the driver on the chip.
Thanks again!
