My MPC8245 can't connect to USB TAP

xuchaoli — Wed, 09 Dec 2015 07:28:07 GMT

If I try to connect MPC8245 by USB TAP,then Codewarrior will give me a error report,picture1;

When I cancel the option of"reset Target on lanuch"in Remote Debugging Tabe ,then ,It will give me a select dialog box,picture2

if i click "No",it will be picture3;

I use two 16bit SDRAM(IS42S16800F) as 32 BIT data width;and My initialization configration file as picture4 and picture5(rewrite from a sandpoint configration file);

I don't know what is wrong? How should I do? Thanks.

As far as I remember, CodeWarrior USB TAP debug probe does not support MPC8245 device working in 32-bit bus mode.

The only 64-bit mode is supported. For 32-bit mode you have to use another debug probe.

Please double check with CodeWarrior team.

Have a great day,

Today,I found that the configration file is written in little-endian,but my cpu work on big-endian,so,I have change it to big-endian,but the same result.when I cancel the"reset target on launch"and click the"yes"button in dialog box,then,it will say:"error resetting target from initialization file". So I think,My inintialization file is something wrong,If you could give me some demo for MPC8245 or some spcification,thanks.

Attached configuration file for MPC8245-based "Sandpoint" development system, we distribute this file with CodeWarrior
