We use Keil tools to generate C++ embedded application that run in our embedded controller.
My initialization code jumps to __main as follows:
IMPORT __main LDR R0, =__main BX R0
Wher is "__main" ?
I searched C:\Keil but could not find definition of __main.
This is what my map file says about __main
__main 0x00008308 ARM Code 8 __main.o(!!!main)
My application starts at 0x8000. __main is at 0x00008308. Where is __main.o ?
in forever loop between __main() and my main(). I se two possibilities a) active watchdog b) no infinite loop in main
I can't debug the code because it's Keil HUH? I know of no means of loading an ARM processor that can not be used for debugging code.
How do I resolve this problem? What do I need to do to get Keil to jump to my main().
you state above "loop between __main() and my main()" so it must "jump to my main()" That you need to clarify.

Well you should probably review your startup.s file, and your target memory settings. Check also if you need to configure registers within your chip, or initialize external RAM, before C can start.
You'll likely have to uncheck "Run to main()" in order to debug the situation.
