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.
Home Questions Tags Users Unanswered. Thank you for your help. You will likely have to provide, or at least customize, this portion of the startup code.

You will have to write your own bootloader for this part. 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. If you don’t need to reprogram the external flash at run time then you may not need the flash driver code. 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 using Facebook. Arduino Robotics Lonnie Honeycutt. How would I be able to put the program on the external flash? I know how to connect those components physically since NXP’s site has an example of this xatasheet was really easy to understand.
Introduction to Microcontrollers Mike Silva. The microcontroller should also be able to read from the external flash without any special driver code.
A good description is given in this application note: Sign in Sign in Remember me Forgot username or password? James Ethridge 11 4.
I’ve contacted Keils support vie email, I thought I’d try here also to see if anyone else has seen this Flash download failed – Target DLL has been canceled”. And if there’s some code involved, or changes to the configuration files, could you please give me an example of how it works? I’m not familiar with the internal bootloader provided with this microcontroller. 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 lpc229 microcontroller’s on chip memories.
Anyaways, here is what I found: Happens every time, I call tech.
It’s configured by the startup code so that the external memories are accessible sooner rather than later. This includes configuring the pins on that part for their alternate functions. Once the External Memory Controller is configured properly, the microcontroller should be able to read and dtasheet to the external SRAM without any additional driver code.
I have the proper crystal freq. But that problems seems to be a lockup during programming, not what I’m seeing. 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.

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. Any ideals, I’m stumped? If someone could explain this to me I would be really grateful.
You could also find an evaluation lpc22944 that contains external memories and reference the eval board’s schematic.
LPC2194 JTAG programming problems…
I’ve stuck on 3 other LPC’s and each has failed in the same way. Once again, an eval board example would be a good reference.
My LPC’s program the 1st time but from then on out I get an error saying: My LPC design is a different story. Here again, if you can find an eval board with external memories then the example program that vatasheet with the eval board will be a great reference.
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? You will need to configure the microcontroller’s External Memory Controller in order datashdet the microcontroller to be able to use the external memories.
I would suggest you make use of the resources and forums at LPCWare www. Refer to the microcontroller documentation for examples on how to connect vatasheet microcontroller to the external SRAM and flash.
However, writing to the external flash will require some special driver code that you will have to incorporate in your program. I’ll post a answer to my own problem. Create lpc22994 account Forgot password? Refer to the flash part’s datasheet for the erase and program algorithms that are required to reprogram the flash.

I doubt that this bootloader will support your external memories automatically. 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 can probably find others. I’ve been working on the LPC design for some time and have not had any problems at all. I’ve two Philips LPC designs. Typically the External Memory Controller gets configured with some instructions in the startup code for your application. I asked this question almost 3 years ago when I was a little lot green.
