Anyways, it works now Chetan Bhargava 4, 5 21 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. I’ve stuck on 3 other LPC’s and each has failed in the same way.

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. You could also find an evaluation board that contains external memories and reference the eval board’s schematic. James Ethridge 11 lpc2294. I would suggest you make use of the resources and forums at LPCWare www.

This includes configuring the pins on that part for their alternate functions. I know how to connect those components physically since NXP’s site has an example of this which was really easy to understand.

Typically the External Memory Controller gets configured with some instructions in the startup code for your application. Create free account Forgot password? Datasheeh to the flash part’s datasheet for the erase and program algorithms that are required to reprogram the flash.

Datasueet asked this question almost 3 years ago when I was a little lot green. I’ll try to field your questions in the order that makes the most sense to me: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works? Home Questions Tags Users Unanswered. 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. Once again, an eval board example would be a good reference. You should be able to read through the data-sheet and figure out what modifications you need to make to the initialization code from that point.

You will have to write your own bootloader for this part. Post as a guest Name. Sign up or log in Sign up using Google.

To get a better understanding of how the external memory controller works with dynamic memory I strongly suggest you also read the technical documentation provided by ARM: 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 able to tell that it has those resources, and use them as if they were the microcontroller’s on chip memories.

For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully. How would I be able to put the program on the external flash?

In order to use external SDRAM you will have to properly configure and initialize the external memory controller on the device. It’s configured by the startup code so that the external memories are accessible sooner rather than later. You will need to configure the microcontroller’s External Memory Controller in order for the microcontroller to be able to use the external memories.


I’ve two Philips LPC designs. I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this Anyaways, here is what I found: I’ve searched the threads here and the LPC errata and see datasheet are some programming problems with devices with early date codes.

If someone could explain this to me I would be really grateful. Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash. You can probably find others. Would I datasehet 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?

Sign up using Facebook. I’ve been working on the LPC design for some time and have not had any problems at all.

Introduction to Microcontrollers Mike Silva. Happens every time, I call tech. 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.

NXP (founded by Philips) LPC

Arduino Robotics Lonnie Honeycutt. For example, you may be able to get by with reprogramming the flash via JTAG with a special flash programming application on your PC. However, writing to the external flash will require dataseet special driver code that you will have to incorporate in your program. Sign up using Email and Password.

A quick google search turned this eval board up:
