Can codewarrior debugger and PowerTAP Pro be used for debugging ROM program which in little endian mode.

processor is mpc862.

PowerTAP Pro cannot be used for the MPC862. It uses JTAG connection to the board. The MPC862 uses BDI connection for code loading and debugging.

See the MPC862 page:

Use USB TAP for PowerQUICC I or Universal Multilink FX:

CodeWarrior Development Studio for PowerQUICC (Classic IDE) v8.8 supports MPC862. It supports little-endian mode.

Have a great day,

Thks for reply.

Are you sure the hardware emulator PowerTAP Pro cannot be used for mpc862?

I know it can,but used in big endian mode.

In addition, I want to know how to protect the processor in order to avoid other person using hardware emulator to debug my program in ROM chip.
