Codewarrior flash programming problem

Hy,

We have a custom board with ls1046a qoriq processor on it. I would like to bring up the board by burning u-boot to the emmc with the CW flash programmer, but while running the target initialization script in CW the error below occurs.

I use the safe RCW in the initialization script. What can be the problem, what does want the CW write at this address?

There is no valid RCW on the target board, in CodeWarrior initialization file please modify "USE_SAFE_RCW = True" to use hard-coded RCW.

If your problem remains, would you please refer to the following procedure to capture protocol CCS log?

Please click Window->Preferences->Debug Sever Connection->Logging Configuration, in PROTOCOL logging panel, please configure "Logging level" as "DEBUG" and check "Enable logging to Eclipse console". Please connect to the target board from Run->Debug Configurations->GDB Hardware Debugging-><project>->Debug, the low level CCS log will be printed in the console.

I cant connect with gdb to the hardware because i am using a blank project and i use the Codewarrior only for flash programming. Should i make this with a helloworld application?

In your CCS log, there is problem at "ccs_reset_to_debug", please refer to the following JTAG interface connection.

Please ensure HRESET not tied to TRST, HRESET to the processor exclusive to COP/JTAG header.
