"Core not responding" when programing MPC8377

[alerk03]

I'm using codewarrior windows version to program MPC8377. The codewarrior version is the newest 8.8.2. I use M29W640GT flash instead of S29GL064R3 on board. But error happens when programing flash like:

Programming 0x00010000 bytes of Target Memory at 0xFE000000

Flash Programmer: CCSProtocolPlugin : Failed to continue thread [Core not responding]

The stop address will change every time. And I can use u-boot to program flash correctlly. So it seems that something is wrong with codewarrior or USBTAP. Could someone helps me to solve the problem?

In situations like this, where flash-programming fails for no discernable reason, I find that slowing the Interface Clock Frequency of the USB TAP or Ethernet TAP usually helps.  From the CodeWarrior IDE Toolbar select Edit->Preferences->Remote Connections.  Double-click on the connection option you're using in the Flash Programmer. In the configuration panel that pops up, change the Interface Clock Frequency option to 1MHz.  You may find that faster speeds also work but start with 1MHz.
