MPC860 with BDM interface

jieyan — Fri, 21 Oct 2016 14:52:32 GMT

My board is MPC860 with only BDM interface(NO JTAG). It is a bare metal board. I have CodeWarrior USB TAP DPI probe (10 pins, the BDM interface on the board is 10 pins too). The board is tested by other tool.

This is the first time I try to use CodeWarrior. I cannot connect to my board by CodeWarrior. I try the hardware diagnostics, the error message is "Please check your JTAG clock speed" and ": --------------------
Hardware Diagnostics: CCSProtocolPlugin::Could not connect to the requested core core #0."

I want to know if CodeWarrior support BDM debug? Why the CodeWarrior think it is JTAG not BDM?

To check USB TAP clock configuration, please open

"Edit" - "Preferences" - "Remote Connections" - "CodeWarrior USB TAB" - "Change"

In "Interface Clock Frequency" it will be "4.03 MHz" (in my case).

In case if everything is correct with clock frequency value, but the device still does not respond to

remote connection, please verify if target device (board) is alive:

Power supplies
HRESET and SRESET status
Clock configuration
Input clock is present
Output clock (CLKOUT) is oscillating
Reset configuration settings

If the problem remains, please send CCS log to me to do more investigation. Please enable CCS log from Edit->Debug version Settings->Remote Debugging->Edit Connection->Enable logging, connect to the target again, the CCS log will be printed in CodeWarrior IDE.

Have a great day,
Yiping
