Lpc2000

Dear Srs,

We are experimenting the ISP downloading using the LPC2142 using the 
Philips Flash Utility 2.2.1 on our board.
When we hit the "Read Device" bottom of the utility we got the 
following message "TYPE NOT SUPPORTED" even receiving the ID number and 
the Version Loader 2.1.of the micro controller.
It seens to me that it is not a hardware problem because the 
TX,RX,reset and P0.14 are identical of the Keil Demo board.
(the demo board uses the LPC2148)
Does anybody has a idea of what's going on?

Regards,
Jan
