I am testing UART Flex IO in low power run mode in 1015RT.

I use the SDK sample and combine UART Flex IO sample.

Please see my attachment.


My code hang up when UART_FlexIO_Init, 


As I know, Flex IO can use in low power mode.


What is the correct way to use UART_FlexIO in low power run mode?

Any limitation?

Or any suggestion?
