PSoC 6 MCU

[trstc_4056926]

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

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?

[trstc_4056926]

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.

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.

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!
