Re: [lpc2000] lpc2294 external bus query

Hi Simon,

>> Does anyone know if it is possible to run with internal FLASH and 
RAM, but also have an additional SRAM and 8-bit peripheral on the 
external bus? <<

I bl**dy well hope it does, otherwise I'm stuffed! <g>

>> >From the data sheet it looks like it should be, but if I run from 
internal FLASH I don't get any bus activity if I try to access the 
external memory. <<

I've only just got my board back, so haven't actually tried it yet, but one 
suggestion would be to check whether you've set up the registers (PINSEL0-2) 
to configure the relevant pins as address and data lines. 

The only other thing I can think is that you haven't setup the compiler to 
access *external* RAM for the relevant locations...

Cheers,

Rob
