CodeWarrior USB Tap in LS1028ARDB: target connection error

I'm using a LS1028ARDB set as LS1027AE (by DIP switches) and I tried to access the Flash Programmer with the CodeWarrior (CodeWarrior Development Studio for QorIQ LS series - ARM V8 ISA) to program the eMMC integrated in the kit. I connect my CodeWarrior USB TAP to the J24 (DUT JTAG). However, I have no success in the connection. I received the error shown in the image attached as Error_CodeWarrior.

 

Then, I used the CodeWarrior Connection Server console to check the USB TAP communication:

(bin) 1 % dele a
(bin) 2 % findcc utaps
USB TAP Serial Numbers:
08060102
08060102
(bin) 3 % source IDcode.tcl

It seems that the USB TAP was recogninized but the board not. I have a CodeWarrior USB TAP 900-75846 Rev A. Someone can explain me what I did wrong? Also, how can I check if the firmware version of my USB TAP is compatible with the LS1028A processor?

 

Thank you in advance,

Igor
