Hello jin xiaofei,

Probably you destroyed RCW on the target board, please use the feature "CodeWarrior JTAG configuration file to override RCW", please refer to the section "Setting up a remote system to use a JTAG configuration file" in C:\Freescale\CW_PA_v10.5.0\PA\Help\PDF\Targeting_PA_Processors.pdf.

In addition, if you use the old product USB TAP, please change the connection type as "USB TAP".

If this problem remains, you need to consider about the hardware problem.


Have a great day,
Yiping

This error happens only after you program your own boot-loader? Before that you were able to connect to the board?
