MC56F8367 Jtag error

Hi,

I am using codewarrior 11.1 to test/debug MC56F8367 with P&E multilink universal .

I have attached files of my schematic, i'm not clear with some pin connections 

1. I have not made reset low. what will happen if it is always high, should i make it low.

2. TRST pin is not pull down, will this affect my communication between debugger and ic.

3. I have connected DE pins to GPIO. I am not clear about the concept of key in jtag, should i have to use it.

While debugging i get an error - An error occurred while connecting to the interface hardware or target specified in the launch configuration dialog.   

 

Things which i made to rectify the error is

Made RESET pin low , connected pull down to TRST pin, left DE floating nothing helped me.

I went through datasheet and example schematic but i cant get any idea out of it.

Can anybody  help me out.

Thanks in advance.
