Greetings.
Thanks for the help.
I can't tell what piece of code is executing that causes the memory
access. It's in the storage heap, so it could well be part of your
program. But there's no embedded function name associated with the
function (you need to enable that option in your development system),
so we can't tell for sure.
How do I enable the option? I'm using CodeWarrior v9.0.

Lim,
The information you provide here seems to indicate that you are
accessing a global variable in your application at a time when global
variables are not available.
The line:
> 0014E682 *CMP.L -$1780(A5),A2
|
>B5ED E880
shows a memory access based on register A5. That register contains
the base address for global variables. The value (0x800F0106) in
your case has the high bit set, indicating that the A5 register has
been marked by the OS to indicate that global variables are not
currently available to your application.
I can't tell what piece of code is executing that causes the memory
access. It's in the storage heap, so it could well be part of your
program. But there's no embedded function name associated with the
function (you need to enable that option in your development system),
so we can't tell for sure.
If you can test your application under the Palm OS Emulator, try
doing that, as it will detect such incorrect memory accesses at the
point they occur and give you a better error message.
