Hi,

Ok, it's missing in test2 because i forgot to port it from the ported project
but in the project
it's there at the beginning of main:
---------------------------------------------
...
ADC12IFG = 0;
ADC12CTL0 |= 0x0002; // Set ENC (Start ADC12)
P5OUT = 0xfe;
IE1 |= 0xc1;
ME1 |= 0xc0;
timer_init ();
// clear interrupt flags
IFG1 = 0x00;
IFG2 = 0x00;
_EINT (); // enable interrupts
// UART1
UCTL1 |= SWRST; // **SWRST**
initSPI ();
...
---------------------------------------------------------
With a manual breakpoint (kernel-panic function which does only LED blinking
with wakeup + _DINT();)
i see that the _EINT(); code has been executed.
I will test the example with _EINT();.
Also why the ISRs are declared "extern
> inline"?

I've done my first porting 1 1/2 years ago and used that declaration. Maybe
it's not correct but because even with -Wall it does not produce a waning/error
which means that mspgcc says it's ok.

I noticed that in debug mode the WDT is faster but MCLK is slower and this
causes side effects, e. g. no communication between 2 MSPs in debug mode.
Therefore i often do use a manual breakpoint.
