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
"What are the required configurations to be done to add this memory into the application?"
Are you talking about settings within the Keil tools - uVision, etc - or settings of processor registers, or settings (eg, jumpers) on the MCB2300 board itself?
Assuming you refer to software changes, you need to configure your LPC2400.s file to enable the proper bank(s) and to setup correct timing parameters for your external memory (to be found in the data sheet of the device).
I am referring to the settings with in the Keil uVision4
So what does the uVision-4 Manual tell you, then?
As it is a Keil board, you should also check the MCB2300 documentation and examples...
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?
