I doubt that this bootloader will support your external memories automatically. Effectively, the microcontroller knows to use dahasheet external memory controller when it executes instructions that access those addresses, so it’s fairly seamless during application development once it’s set up. I’ll try to field your questions in the order that makes the most sense to me: I’ll post a answer to my own problem.

Sign up datashheet Email and Password. But that problems seems to be a lockup during programming, not what I’m seeing. 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. For this, I’d recommend studying the chapters on pin configuration and 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’ve searched the threads here and the LPC errata and see there are some programming problems with devices with early date codes.

A quick google search turned this eval board up: You will have to write your own bootloader for this part. My LPC design is a different story. Once again, an eval board example would be a good reference.

You vatasheet also find an evaluation board that contains external memories and reference the eval board’s schematic. My LPC’s program the 1st time but from then on out I get an error saying: James Ethridge 11 4. I’ve been working on the LPC design for some time and have not had any problems at all. Post as a guest Name.


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 datashset method to write on the flash or Dafasheet, 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.

How would I be able to put the program on the external flash? I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this Post Your Answer Discard 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.

I would suggest you make use of the resources and forums at LPCWare www. I asked this question almost 3 years ago when I was a little lot green. Typically the External Memory Controller gets configured with some instructions in the startup code for your application. Anyaways, here is what I found: Happens every time, I call tech. Chetan Bhargava 4, 5 21 Flash download failed – Target DLL has been canceled”. Refer to the microcontroller’s User Guide for details on how to configure the External Memory Controller.

LPC datasheet & applicatoin notes – Datasheet Archive

Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash. Lpc22294 parts that fail to program a second time run their initially flashed program just fine, I just can’t get at the JTAG port.

Here again, if you can find an eval board with external memories then the example program that comes dafasheet the eval board will be a great reference. Thank you for your help.


NXP (founded by Philips) LPC2294

And if there’s some code involved, lpcc2294 changes to the configuration files, could you please give me an example of how it works? You will likely have to provide, or at least customize, this portion of the startup code. It’s configured by the startup code so that the external memories are accessible sooner rather than later.

LPC2194 JTAG programming problems…

I know how to connect those components physically since NXP’s site has an example of this which was really easy to understand.

A good description is given in this application note: 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?

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

If you don’t need to reprogram the external flash at run time then you may not need the flash driver code. The microcontroller should also be able to read from the external flash without any special driver code.
