Hi, basically it *is* possible to do what you want, but it's not that easy as you might think. As you want to have the possibilty to exchange the *complete* flash data (that means not only an application area) and the LPC's can not write into the flash memory execting from you have to do as follows: You must write a so-called secondary bootloader, which is fully running in RAM (ima...

Hi, As I need to add some more speed when executing from external flash I thought that it would be a good idea to use burst mode flash devices (the m58bw016 from ST for example). But these devices need a few control signals like ^B, ^L and K. Where K is the input for a clock signal like that from xclk/p323. But then I need to connect the ^B and ^L si

In other words, if the code is running from ext. flash and the R/W mem region is in Ext-Ram, the code doesn't work well (think it reads 0 from memory location instead of correct data). If I move the code to the internal flash, it runs fine; or in some cases ...
