Fixed - user error, pin had moved and pwm wasn't reassigned.

Just to confirm, according to the Registers UART0, SPI0 are off.

So debugging can't occur without P0.08/Uart?

I've stripped much of the bloat away so I'm not using nrfx etc directly, although some of the libraries are continuing to import. As far as I can tell all UART_Enabled type statements in SDK_CONFIG are turned off. Certainly the only LOG type one I've enabled is RTT.

Note that P0.08 is used as a UART pin in most of our examples for debugging purposes. This is defined in the pca10040.h header file (if that's the one defined in your project). You can try changing this to something else in your project to see if that changes anything.

Best regards,

Simon

I've now swapped the chip with the same result.
