It is just because you do not clear current active interrupt in timer ISR. Please add below line at beginning of Timer1_Isr():
In addition, the indicating LED used in Timer1_Isr() is not hard-wired on 062-kit board, you can use RED_LED (p0_3) instead;
SMIF function reports building error, so you need configure the SMIF with referring SMIF code example or using SMIF configuration tool.

I could not find a reference to Cy_TCPWM_ClearInterrupt() API in the PDL description for TCPWM. What am I missing?
Thanks so much - that was the issue, I was forgetting that it was Timer1 that was causing the interrupt and I needed to clear the Timer1 interrupt flag or I'd be stuck in the ISR forever - one thing that was throwing me was that I didn't see P7.7 going high but that was because it isn't connected on the eval PCB.
As you can see, I haven't got into setting up the SMIF yet but I have tested another project that runs SMIF on the same pins to talk to the on-board flash memory chip and it seems to work fine (I get no compile errors).
I have designed and am making up, a PCB that the CY8CKIT-062-BLE board plugs into and P7.7 is wired to drive an LED on that external PCB - now I see that you're right that my signal doesn't actually come out of J18 pin 1 as R87 isn't populated on the 062-BLE board - given I don't want to use the CAPSENSE stuff I will populate R87 and move on but where is the documentation that tells me what other pins are not connected on the headers?
