Compiling and debugging for s3c2440 in keil without RTOS

Hello all,

I'm trying to understand the architecture of s3c2440 and wish to interface all components without RTOS to understand how it functions. I'm facing the following problems:

--> I've been trying to compile it in keil but the it gives multiple syntax errors and does not compile. I some how mannaged to solve a few errors and compile the GPIO experiment and debug it. It worked fine. Then when I compiled the UART experiment it does not debug also. probably some mistakes that i've done in the startup file.

--> Using Keil4, what ROM start address and size should I define?

--> While debugging I am getting that some addresses are not accessible because they are write protected or read protected. How can I overcome this?

.

==> Any startup files other tahn the one generated by the IDE if available will help.

==> Also if there are any basic experiments done in keil and can post them, i will be thankful.

Regards,
