MPC8640D Failed to reset the target (core did not halt)

Hi all,

we are working on a project CPCI Based SBC Board using MPC8640D processor.

We are trying to get simple JTAG connection to the processor mpc8640d. We

are using code warrior USB tab s/n 0839 0023.

In code warrior, when I try to reset the MPC8640D core (via reset target

on launch), it gives the following message:

"CCSProtocolPlugin: Failed to reset the target (MPC8640d Core: Core did not

halt)."

we are monitoring the jtag signals also , HREST and SRESET signals are not

coming..by default these signals are in high state(+3.3v).

Can you give me some guidance in interpreting this error ?

Thanks and Regards,

Jyothi

Hi,

Duplicated to the SR# 1-3927022918.

This error means the debugger can not take control over the core. Usually, this happens if core is not responsible to debugger commands - did not come from reset, or entered checkstop state due to some error condition.

If the core does not core from reset, than please ckeck basic things - power on configuration, clocking, power supplies, etc.

Have a great day,
