I’ve searched the threads here and the LPC errata and see there are some programming problems with devices with early date codes.

LPC2194 JTAG programming problems…

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. 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. 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.

My LPC’s program the 1st time but from then on out I get an error saying: If you don’t need to reprogram daatasheet 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. I asked this question dataheet 3 years ago when I was a little lot green.

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 do something else?

LPC datasheet & applicatoin notes – Datasheet Archive

A good description is given in this application note: I’ll post a answer to my own problem. Effectively, the microcontroller knows to use the external memory controller when it executes instructions that access those addresses, so it’s fairly seamless during application development once it’s set up.


Sign up or log in Sign up using Google. Chetan Bhargava 4, 5 21 Anyways, it works now You will have to write your own bootloader for this part.

I’m not familiar with the internal bootloader provided with this microcontroller. I doubt that this bootloader will support your external memories automatically. Any ideals, I’m stumped? Flash download failed – Target DLL has been canceled”. I have the proper crystal freq. For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully. Introduction to Microcontrollers Mike Silva. Happens every time, I call tech.

Create free account Forgot password? In order to use external SDRAM you will have to properly configure and initialize the external memory controller on the device.

A quick google search turned this eval board up: 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’ve been working on the LPC design for some time and have not had any problems at all. How would I be able to put the program on the external datasheett But that problems seems to be a lockup during programming, not what I’m seeing.

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 datashete create a method datassheet 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.


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

Arduino Robotics Lonnie Honeycutt. My LPC design is a different story.

Eatasheet know how to connect those components physically since NXP’s site has an example of this which was really easy to understand. You will need to configure datasheeet microcontroller’s External Memory Controller in order for the microcontroller to be able to use the external memories. This includes configuring the pins on that part for their alternate functions. 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.

Email Required, but never shown. Typically the External Memory Controller gets configured with some instructions in the startup code for your application. Sign in Sign in Remember me Forgot username or password?

If someone could explain this to me I would be really grateful. 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.

Philips – datasheet pdf

Refer to the flash part’s datasheet for the erase and program algorithms that are required to datasheft the flash. Once again, an eval board example would be a good reference. It’s configured by the startup code so that the external memories are accessible sooner rather than later. I’ve stuck on 3 other LPC’s and each has failed in the same way.
