However, writing to the external flash will require some special driver code that you will have to incorporate in your program.

NXP (founded by Philips) LPC2294

Refer to the microcontroller’s User Guide for details on how to configure the External Memory Controller. James Ethridge 11 4. Anyways, it datashfet now 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.

My LPC design is a different story.

You will likely have to provide, or at least customize, this portion of the startup code. Any ideals, I’m stumped?

In order to use external SDRAM you will have to properly configure and initialize the external memory controller on the device.

A good description is given in this application note: This includes configuring the pins on that part for their alternate functions. I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this I’ve two Dataasheet LPC designs.

I’m not familiar with the internal bootloader provided with this microcontroller. Arduino Robotics Lonnie Honeycutt.

How would I be able to put the program on the external flash? Is it only necessary to connect it via hardware and put LOW or HIGH on some pins on boot for lpc22294 microcontroller to recognize those external resources as its own, or will I also have to do something else? Introduction to Microcontrollers Mike Silva. To get a better understanding of how the external memory controller works with dynamic memory I datashwet suggest you also read the technical documentation provided by ARM: Sign up using Facebook.

A quick google search turned this eval board up: 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. Lpc2924 post a answer to my own problem.

Anyaways, here is what I found: Typically the External Memory Controller gets configured with some instructions in the startup code for your application. I know how to connect those components physically since NXP’s site has an example of this which was really easy to understand.

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. For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully.

The parts that fail to program a second time run their initially flashed program just fine, I just can’t get at the JTAG port. 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.

It’s configured by the startup code so that the external memories are accessible sooner rather than later. Chetan Bhargava 4, 5 21 Refer to the flash part’s datasheet for the erase and program algorithms that are required to reprogram the flash.
