5 TROUBLE SHOOTING
Q
The ICE is reset spontaneously sometimes in ICE mode.
A
It occurs when the user maps his network printer to the LPT1 that is connected to the ICE system.
To solve it, just map the network printer to LPT2.
Q
ICE can’t work under Windows 2000.
A
When ICE works under Windows 2000/ Windows XP, LPT port should be set in the BIOS. Please
check the BIOS about the LPT configuration. It must be EPP, ECP, or Bi-direction.
Q
Could ICE work emulate the 3.3 voltage supply?
A
Yes. Just remove the “INTERNAL 5V” jumper (near the RESET button) and supply the 3.3V DC
power to the VDD and VSS pin of CON1 (I/O port interface) by target board.
