I have a frdmkl43z eval board and am trying to run the power_manager demo.

When I run the demo and choose mode C and a Timer of 5s this is what happens

 

P&E Semihosting Console

 


####################  Power Manager Demo ####################

 

    Core Clock = 48000000Hz
    Power mode: RUN

 

Select the desired operation

 

Press  A for enter: RUN      - Normal RUN mode
Press  B for enter: WAIT     - Wait mode
Press  C for enter: STOP     - Stop mode
Press  D for enter: VLPR     - Very Low Power Run mode
Press  E for enter: VLPW     - Very Low Power Wait mode
Press  F for enter: VLPS     - Very Low Power Stop mode
Press  G for enter: LLS/LLS3 - Low Leakage Stop mode
Press  H for enter: VLLS0    - Very Low Leakage Stop 0 mode
Press  I for enter: VLLS1    - Very Low Leakage Stop 1 mode
Press  J for enter: VLLS3    - Very Low Leakage Stop 3 mode

 

Waiting for power mode select..

 

C
Select the wake up source:
Press T for LPTMR - Low Power Timer
Press S for switch/button SW3.

 

Waiting for key press..

 

Wrong value!
Select the wake up source:
Press T for LPTMR - Low Power Timer
Press S for switch/button SW3.

 

Waiting for key press..

 

T5
Select the wake up timeout in seconds.
The allowed range is 1s ~ 9s.
Eg. enter 5 to wake up in 5 seconds.

 

Waiting for input timeout value...

 

5
Will wakeup in 5 seconds.

 

 

The board never wakes up.

 

 

Why does a demo shipped with the board not work?

 

Thanks, John
