Hi, 

we are 4 students, we are trying to debug an application on the 
lpc2148. We use an Olimex cable to connect to the prototype board of 
EmbeddedArtists 
(http://www.embeddedartists.com/products/boards/prototype.php). Our 
problem : OCDRemote says 
OCDemon InitializeTarget Error : Cable Disconnected

We followed the debugging steps from (ARM Cross Development with 
Eclipse, Version 3 by Jim Lynch).

When we connect the Wiggler to the board, it seems that it stays in 
reset mode. 

Can anybody help us with this problem?

I have the same board and the same cable and some time ago I looked
into this problem.

I ran into the following things:
* recent versions of OCDRemote expect a link between pins DATA6
  and ERRORn. Possibly you have an older cable that does not have
  this link.
* the olimex cable expects a high level on the DATA7 pin and possibly
  OCDRemote is not putting a high-level on this pin.
* OCDRemote may be too quick to try to communicate with the board
  after a reset. It appears that the embedded artists board has a
  reset chip that keeps the LPC in reset for some minimum amount
  of time.

I was able to connect to the board with ocdremote at the very
lowest speed, but that is unworkably slow.

Some people claim that it is required to configure the parallel
port in the BIOS for SPP or EPP, not ECP.

I suggest to try out the open-source OpenOCD instead, see

EPP is required for the Macraigor software to work properly. Also, pins 1 
and 18 should be connected at the DB-25.

Don't you mean pins 8 and 15?
If not, what is the connection between pin 1 and 18 good for?

I meant 8-15.
