Lpc2000

Hi, Folks,

Hopefully, someone can shed some light to this. Thanks.

First, this is not my first app on the LPC2138. I had no trouble 
before, until I use IAP in this one.

The IAP calls seem working OK. No error reported. Flash memory does 
program as expected, as far as I can see.

But, a simle C structure in one of the functions now behaves wierdly 
SOMETIMES. This is called repeatedly in a loop.

switch(m_CmdTmp) {
case 1:
    ..... codes here
    m_CmdTmp=2;
    break;
case 2:
    if(!Started()) {
         Starting();         <<====== Point 1
         // some other stuff ... here
         m_CmdTmp=3;
    }
    break;
case 3:
    ...
    break;
}

After some poking around, I found I am at Point 1 while m_CmdTmp 
already equals 3 (m_CmdTmp=3).
There is no interrupts changing the value of m_CmdTmp behind my 
back ! m_CmdTmp is supposed to progress ONLY in this switch routine.

I tried to change stack sizes to no avail. I reserved 256 bytes from 
the TOP of SRAM (0x400007e00 and up) from being used by this APP. 
No, I still have this problem.

Any ideas ?

Thanks a lot,

Greg
