Then I would suggest get an eval board that comes with demo code for setting datashdet the external memory controller and initialization code for the SDRAM on the eval board.

James Ethridge 11 4. My LPC’s program the 1st time but from then on out I get an error saying: I’ll try to field your questions in the order that makes the most sense to me: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Sign up using Facebook. 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. 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.

Lpc2924 this, I’d recommend studying the chapters on pin configuration l;c2294 the external memory controller in the LPC user manual carefully. I’ve stuck on 3 other LPC’s and each has failed in the same way. I’ll post a answer to my own problem. Create free account Forgot password? This includes configuring the pins on that part for their alternate functions.

Any ideals, I’m stumped? You will have to write your own bootloader for this part. 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: 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.

Sign up using Email and Password. If someone could explain this to me I would be really grateful. I doubt that this bootloader will support your external memories automatically. Flash download failed – Target DLL has been canceled”. Sign up or log in Sign up using Google.

Refer to the flash part’s dafasheet for the erase and program algorithms that are required to reprogram the flash. And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works? 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 datasheer 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.

Anyways, it works now A quick google search turned this eval board up: 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 daatsheet connect those components physically since NXP’s site has an example of this which was really easy to understand.

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

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. Introduction to Microcontrollers Mike Silva. If you don’t need to reprogram the external flash at run time then you may lpc294 need the flash driver code.

The microcontroller should also be able to read from the external flash without any special driver code. I have a project in mind.

Philips – datasheet pdf

But that problems seems to be a lockup during programming, not what I’m seeing. Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash.

Home Questions Tags Users Unanswered. Typically the External Memory Controller gets configured with some instructions in the startup code for your application. I would suggest you make use of the resources and forums at LPCWare www. Thank you for your help. 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 the microcontroller to recognize those external resources as its own, or will I also have to datssheet something else?

Anyaways, here is what I found: Once again, an eval board example would datasheeg a dtaasheet reference. Refer to the microcontroller’s User Guide for details on how to configure the External Memory Controller. However, writing to the external flash will require some special driver code that you will have to incorporate in your program. Sign in Sign in Remember me Forgot username or password?

You could also find an evaluation board that contains external memories and reference the eval board’s schematic. You can probably find others. You will likely have to provide, or at least customize, this portion of the startup code. Chetan Bhargava 4, 5 21
