Environment: MCUXpresso, K81 target, Segger J-Link debug probe,
Reference: MCUXpresso IDE and Semihosting
With Semihosting the printf output appears in the MCUXpresso Console, as expected. However, when I switch to UART (Quick Settings -> SDK Debug Console -> UART Console) no output is seen on the LPUART. With UART selected, no output is sent to the MCUXpresso Console, as expected.
I have checked that the SDK_DEBUGCONSOLE define is correctly set (Quick Settings -> Defined Symbols).
I have also checked that the LPUART settings (In my case this is LPUART2 on PTD2/3.) are good.
BTW, LPUART Debug output works just fine with my projects on IAR EWARM, so I know the physical HW is OK.

Oops! Found the problem, it is not directly related to the routing of the debug console. It's about printf(). The code uses DEBUG_PRINT(), defined as follows:
define DEBUG_PRINT(fmt, ...) printf("%s: " fmt, __FUNCTION__, ##__VA_ARGS__)
I.e. it uses printf instead of PRINTF. (Only PRINTF will work as it's defined as DbgConsole_Printf)
