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.

My LPC’s program the 1st time but from then on out I get an error saying: For example, you may be able to get by with reprogramming the flash via JTAG with a special flash programming application on your PC. I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this Sign in Sign in Remember me Forgot username or password? I asked this question almost 3 years ago when I was a little lot green. But that problems seems to be a lockup during programming, not what I’m seeing.

A quick google search turned this eval board up: James Ethridge 11 4. 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.

A good description is given in this application note: You could also find an evaluation board that contains external memories and reference the eval board’s schematic. Thank you for your help. If someone could explain this to me I would be really grateful. Would I have to write a bootloader and record it manually on theexternal flash or dayasheet I just use the internal bootloader, and somehow map it to the external devices?

You can probably find others. My LPC design is a different story.

Anyaways, here is what I found: I have a project in mind. Refer to the microcontroller documentation for examples on how to connect the microcontroller to the external SRAM and flash. You should be able to read through the data-sheet and figure out what modifications you need to make to the datasheey code from that point.

Chetan Bhargava 4, 5 21 In order to use external SDRAM you will have to properly configure and initialize the external memory controller on the device. Arduino Robotics Lonnie Honeycutt. Email Required, but never shown. For this, I’d recommend studying the chapters on pin configuration and the external memory controller in the LPC user manual carefully.

You will have to write your own bootloader for this part. You will likely have to provide, or at least customize, this portion of the dafasheet code. I’m not familiar with the internal bootloader provided with this microcontroller. It’s configured by the startup code so that the external memories are accessible sooner rather than later. Once the External Memory Controller is configured properly, the microcontroller should be able to read and write to the external SRAM without any additional fatasheet code.

Happens every time, I call tech. I have the proper crystal freq.

Once again, an eval board example would be a good reference. I would suggest you make use of the resources and forums at LPCWare www. Sign up using Email and Password.

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. Typically the External Memory Controller gets configured with some instructions in the startup code for your application. Flash download failed – Target DLL has been canceled”.

The microcontroller should also be able to read from the external flash without any special driver code. You will need to configure the microcontroller’s External Memory Controller in order for the microcontroller to be able to use the external memories.
