working on low power mode SDK of S32k144 in which print function(print((const char *)MENU_MESSAGE ADD_MESSAGE);) is not working not displaying any messages on putty and as per code i set baudrate as 9600.unable to see any response and readoptionconsole function is also not executing.is there any problem with this SDK code.Please support this issue to solve the problem.
