I'm using PSOC4 - CY8C4245PVI with external clk of 10Mhz at P0.6. This is working fine.

But my UART (SCB) is not working. I've configure UART for 115200baudrate.

How to judge the system work fine?

The same project, if you change  HFCLK clock to IMO, does it work?

Could you share your test project here?

Driving LED with timer, on/off time of LED is changed according to HFCLK (24Mhz to 10Mhz).

Yes!!!

1: I use the external clock 4MHz to test the function, the UART can work well.

2: What's the accuracy of the 10MHz? How do you get the clock?

3: Does the voltage match with each other? (PSoC, 10Mhz generator)

4: Choose the right COM Port.

5: Hope it can be helpful for you~
