Unable to access ext memory on EVBA7 with 144 Pin Adapter

2004-08-22 by helicopterproject2003

I have a EVBA7 with a 144 pin adapter with a LPC2214 chip. The 
adapter has 1MB of RAM which I think starts at 0x80000000. I also 
belived it is hardware straped to startup in 32bit data bus mode.

I can't seem to write anything into this memory. Even if I use the 
JTAG and IAR debugger to set any memory location above 0x8000000 it 
stays set to zero which makes it appear to not be working at all or 
incorrectly addressed.

Anyone have any ideas?

Thanks
Rick
