T1024 in hardcoded mode

Currently I am debugging T1024 CPU, on our board there is no programmed image in NOR flash, nor in NAND flash, we need to program the information via CodeWarrior. We use hardcoded mode and the cfg_srw is set to 0,1001,1110 (we used  100MHz differential clock mode).

In Codewarrior, attached mode, we select the target type is T1024, and the connection is successful. while in sometime, the CPU's register is not accessible, sometime, it is accessible. When we change the target type to out defined RCW (from .txt file), then there is problem “failed” to configure the JTAG chain (no matter the "override" function in RCW.txt is enabled or not). Based on test, we saw there is COP_HRESET asserted in this configuration, it is strange.

In Codewarrior, connected mode, we select the target type is T1024, and the connection is not successful and the problem is that the CPU core no responding. When we change the target type to out defined RCW (from .txt file), then there is problem “failed” to configure the JTAG chain (no matter the "override" function in RCW.txt is enabled or not).

 

From the document, we do not get the detailed definition for hardcoded POR source, what is the definition? Does somebody know?

It will be appreciated if somebody can help on this problem or some hints, thanks in advanced.
