Hi All,

I am new to ARM and currently working on a design that uses and 
LPC2131.  I am using CrossStudio and having some problems.  When I 
start debugging it gives me Verification errors after downloading.  I 
am using a Seggar J-Link that came in an IAR kickstart kick.  The 
verification errors begin at 0x1000.  Anything before that programs 
just fine.  Any ideas?

It's quite possible that you need to update you JLink driver. The
current on is 3.12c. I've seen a lot of problems downloading with the
older drivers. Hope this helps.

For a bit more info:

I have a demo board with a LPC2138 and the code will
download to it just fine.  On my product which has a
LPC2131 it won't.

It turns out that my problem was with the CrossWorks
loader.  The code didn't have support for the LPC2131
and the default was another "geometry".  I added
support and all is good.  

On a side note, I tried upgrading the firmware and
driver for the j-link.  This caused me all sorts of
grief with CrossWorks.  I would get USB communication
failures, timeouts, ect...  I could unplug/disconnect
the j-link and say a little chant and it would work
for a bit and then quite.  As it turns out, the new
driver/firmware comes with a new dll.  Once I replaced
the dll in the CrossWorks bin directory, all is good
again.
