I’ll try to field your questions in the ,pc2294 that makes the most sense to me: 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. 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: If you don’t need to reprogram the external flash at run time then you may not need the flash driver code.

vatasheet How would I be able to put the program on the xatasheet flash? 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? I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this Refer to the flash part’s datasheet for the erase and program algorithms that are required to reprogram the flash.

Any ideals, I’m stumped? You datasheey 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 fine, I just can’t get at the JTAG port. Create free account Forgot password?

Arduino Robotics Lonnie Honeycutt. I have a project in mind. The microcontroller should also be able to read from the external flash without any special driver code. In order to use external SDRAM you will have to properly configure and initialize the external memory controller on the device.

I’m not familiar with the internal bootloader provided with this microcontroller. You will have to write your own bootloader for this part. I would suggest you make use of the resources and forums at LPCWare www.

If someone could explain this to me I would be really grateful. Sign up using Email and Password. I’ve searched the threads here and the LPC errata and see there are some programming problems with devices with early date codes. James Ethridge 11 4.

It’s configured by the startup code so that the external memories are accessible sooner rather than later. 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? You could also find an evaluation board that contains external memories and reference the eval board’s schematic.

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 lpc229 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.

My LPC’s program the 1st time but from then on out I get an error saying: Anyways, it works now This includes configuring the pins on that part for their alternate functions.

Once the Dataaheet Memory Controller is configured properly, the microcontroller should be able to read and write to the external SRAM without any additional driver code.

And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works? Email Required, but never shown. Then I lpf2294 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.

Home Questions Tags Users Unanswered. I’ve two Dafasheet LPC designs. For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully. Sign in Sign in Remember me Forgot username or password?

Refer to the microcontroller documentation for examples on how to connect the datassheet to the external SRAM and flash.
