Hi, do all LPC2xxx processors support ISP? What about the types without internal flash, e.g. lpc2290? Can I load up data with ISP to the external flash? Kind regards, J\ufffdrg. -- - StGB \ufffd\ufffd 328 Absatz 2, Nr.3 : Mit Freiheitsstrafe bis zu f\ufffdnf Jahren oder mit Geldstrafe wird bestraft, wer eine nukleare Explosion verursacht.

Hi Joerg, all LPC2000 micros support ISP. In case of the Flashless devices such as the LPC2210 and LPC2220, the ISP support loading a program into the SRAM. This program could be a programming sequence for external Flash. As far as I know, the Keil compiler has support for several external Flash devices but otherwise it would be up to you, to write the flasher software to be downloaded into the LPC22x0 Bob

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? > This program could be a programming sequence for external Flash.

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 Dan Beadle _____

There are two mechanisms used with JTAG: 1) Load some software into RAM and use that to program the NAND or simulate this via JTAG debug sequences. 2) Boundary scan. This is not supported by all devices.
