Datasheey it only necessary to connect it via hardware and put LOW or HIGH on some pins on boot for the microcontroller to recognize those external resources as its own, or will I also have to do something else? My LPC design is a different story. I have the proper crystal freq. I’ve two Philips LPC designs. Then I would suggest get an eval board that comes with demo code for setting up the external memory controller and initialization code for the SDRAM on the eval board.

Anyways, it works now If you don’t need to reprogram the external flash at run time then you may not need the flash driver code. A quick google search turned this eval board up: Once again, an eval board example would be a good reference.

Sign up using Email and Password. Anyaways, here is what I found: You could also find an evaluation board that contains external memories and reference the eval board’s schematic.


Would I have to write a bootloader and record it manually on theexternal flash or can I just use the internal bootloader, and somehow map it to the external devices? I’m not familiar with the internal bootloader provided with this microcontroller.

What I want to do is connect those ICs to the microcontroller in order to expand its Program memory and data memory automatically which means that I don’t want to have to create a method to write on the flash or SDRAM, I want the microcontroller to be lpc294 to tell that it has those resources, and use them as if they were the microcontroller’s on chip memories. But you may be able to get the source code for the internal bootloader and then customize it by adding support for your external memories.

I know how to connect those components physically since NXP’s site has an example of this which was really easy to understand. James Ethridge 11 4. A good description is given in this application note: I’ll post a answer to my own problem. Arduino Robotics Lonnie Dataaheet. For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully.

This includes configuring the pins on that part for their alternate functions. And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works? I asked this question almost 3 years ago when I was a little lot green.

You will have to write your own bootloader for this part. But that problems seems to be a lockup during programming, not what I’m seeing. How would I be able to put the program on the external flash? I doubt that this bootloader will support your external memories automatically. Home Questions Tags Users Unanswered. Datashdet you for your help.

Basically each memory will be associated with a chip select pin and you will have to configure all the settings associated with the chip selects that you are using. Here again, if you can find an eval board with external memories then the example program that comes with the eval board will be a great reference.

Once the External Memory Controller is configured properly, the microcontroller should be able to read and write to the external SRAM without any additional driver code.

Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash. Refer to the microcontroller’s User Guide for details on how to configure the External Memory Controller.
