About PowerPC little-endian debug

[tomlucas]

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

processor is mpc862.

[Pavel]

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.
