DaVinci::Exception in KernelInit

hi,
i am currently into OAL development for ARM926 processor and i am suing CCS
verson 3.2 (Code composer studio of Texas Instruments).I am facing a problem
wherein my system HALTS when kernel code reaches the line "KSTKBASE(pTh) =
(DWORD)lpStack;" in MDCreateThread(). I have found many post similar post
concerning this halting when code reaches the above thread but nowhere I am
able to get a workable solution.
i am using a cloned BSP of MAINSTONE2 and during development I
had kept a stub function for OEMDataAbortHandler. But on going through many
messages of these group i made the function (OEMDataAbortHandler)to call
DataAborthandler code whose defination in armstrap.s file.
I also saw in one post where in a problem was faced by an person in the same
line "KSTKBASE(pTh) = (DWORD)lpStack" which he says that maybe due to the
debugger used. So also please let me know if my CCS debugger is created any
problem, and if not how can i further continue please do help me into this as
I am stuck into the code from atleast a week now

thanks in advance
Waiting for a favorable reply

Sorry for breaking the thread
to add more to above post which i forgot to add
when instead of having a single step in the kernel, when I do a complete run
ie F5 the msg that i sometimes recieve on the serial post is "Inside
OEMInterrupthandler" which is repated 6 to 7 times and then the sys halts

You may have a problem in your interrupt handler. At this point interrupts
have been enabled, so if you have a stuck interrupt the system will lockup.
The other thing to look at is your cache routines.

hi,
first of all thanks for your very quick response
What you mean is correct my interrupts are enabled and i think we have to do
it in OALInterrupt (). Also I hink that the timer interrupt must be getting
called because the initialization is done such that timer interrupts after
evey 1 msec. Do you think it will favor or it is right to disable all the
interrupt ir i should not have enabled in init itself

Also about your second possibility that i should look at my cache routines ,
so actually microsoft provides the cache routine for OEMCacheRangeFlush which
is getting called by kernel after OEMInit
I would like to know are there any compulsary Cache routines i am missing out
please do help me into it

thanks in advance
