I am working on MCB2300 (with LPC2378 processor). This processor supports external memory and it has got two banks (at locations 0x80000000 and 0x81000000 respectively with each having size of 64K). I need to use it in my application. What are the required configurations to be done to add this memory into the application? Please let me know
You have, of course, read the user manual information? And noticed that the Keil Configuration Wizard (if you use the correct startup file) have menu settings to enter the required parameters? What the correct parameters are? That depends completely on what you want to do and what external hardware you have - they are configurable just because they need to be different depending on specific users needs. You are that specific user, so the only one who can know what is correct settings for your system.
Note that when you have configured the external memory using the Keil Configuration Wizard, then the project needs to know about the availability of these memory regions. But that shouldn't represent a problem, should it?
