Lpc2000

Hello,

I'm trying to get a new PCB up and running using an LPC2214, but 
cannot get the chip to talk to the JTAG port. I'm fairly new to both 
the processor, and ARM in general, so sorry if this is a really dumb 
problem.

I'm using a Segger J-Link (IAR rebadged) and Rowley compiler.

I have connected to and run test code on the Olimex LPC2214 
development board, so I know the J-Link is OK.

I have checked and double checked the JTAG connection against the 
Olimex schematic.

I have the BSL (P0.14) connected to a pullup. Boot0 and Boot1 are 
open circuit (high through internal pullups). RTCK is pulled low by 
10K. 

The processor oscillator is running.

I've scoped the levels on the JTAG interface with the J-Link 
unplugged, and they are identical on my and the Olimex board, with 
the exception of TCK, which is at 0V on my board and approx 0.4V on 
the Olimex board

Whenever I try to connect from the Rowley IDE I get "Too few devices 
on the JTAG bus. Selected Device :0, No. of Devices 0". I guess this 
means the JLink simply can't see the processor for whatever reason.

The board and chip are new, and have not have any code downloaded 
into them. Do I need to download code using the Flash Loader utility 
from the Phillips website, or should I be able to connect straight 
away through the J-Link? 

Does everything else sound OK, or could I have got a duff processor?


Thanks
