LPC datasheet & applicatoin notes – Datasheet Archive
I would suggest you make use of the resources and forums at LPCWare www. You will need to configure the microcontroller’s External Memory Controller in order for the microcontroller to be able to use the external memories. But that problems seems to be a lockup during programming, not what I’m seeing.
I’ll try to field your questions in the order that makes the most sense to me: My LPC design is a different story. Thank you for your help. This includes configuring the pins on that part for their alternate functions.
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. 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.
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.
I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this I’ve been working on the LPC design for some time and have not had any problems at all. 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. It’s configured by the startup code so that the external memories are accessible sooner rather than later.
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: I’ve stuck on 3 other LPC’s and each has failed in the same way. 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.

Flash download failed – Target DLL has been canceled”. Basically each memory will be associated with a chip select pin and you will have to configure all the lpc229 associated with the chip selects that you are using. 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?

For this, I’d recommend studying the chapters on pin configuration and the external eatasheet controller in the LPC user manual carefully. I doubt that this bootloader will support your external memories automatically. I’ll post a answer to my own problem. I asked this question almost 3 years ago when I was a little lot green.

Any ideals, I’m stumped? You will likely have to provide, or at least customize, this portion of the startup code.
The parts that fail to program a second time run their initially flashed program just dafasheet, I just can’t get at the JTAG port. 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?
microcontroller – Expand RAM and flash on LPC – Electrical Engineering Stack Exchange
I’ve two Philips LPC designs. Anyways, it works now And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works?
Arduino Robotics Lonnie Honeycutt. Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash. I’ve searched the threads here and the LPC errata and see there are some programming problems with devices with early date codes. Anyaways, here is what I found: Home Questions Tags Users Unanswered.
