Lpc2000

An other tool for programming external flash with JTAG is the BDI1000/2000 from abatron (www.abatron.ch). Look at products and then ARM/RDI Support. It works great and you can it use for debugging too.
 
Best regards

Yes, you can use JTAG to load a program into external flash.  But you will need some kind of driver to do that.



I use the IAR tools.  They have a framework source for programming flash. The tools come with pre-built loaders for the Phillips internal flash parts.  It can be adapted to external flash.  I have done such a modification for the SHARP LH7xxxx family of parts using Intel StrataFlash.



The general strategy for external flash is to download a burner program into RAM which then runs and reads the target image.  It is responsible for burning the image into Flash.  



There are also stand-alone tools that will use JTAG to burn.  These use the same strategy, but are not coupled to the IDE.  (e.g. IAR).  Tools are available from Segger for their JLink, Nohau for their JTAG (but you have to hook up the driver), Macraigor (I believe), and I think MicroCross has some tool for GNU toolchain.  



With all of these, you probably have to write a few line macro to tell the program how to disable write protection on the flash.



If you need IAR flash tools, let me know

Can I use IAP for this?

Someone told me I can use the JTAG adapter to load the program into
external flash. Is this true? How fast is JTAG? More than 56k?

Thanks for this clarification.

Bye, Jörg.
