Connet MPC8245 to CodeWarrior

[xuchaoli]

I have config the MPC8245 with 32-bit width SDRAM, Alexander.yakovlev  tell me that USB TAP only support 64-bit width SDRAM,so can you tell me what TAP can use to connect  32-bit MPC8245?

My MPC8245 can't connect to USB TAP

I need to connect my board,but you said that that kind of solution is not accessable, so would youtellme if there any solution I can get. Thank a lot.

Hello xuchao li,

Did you try CCS commands or only CW?

I don't know what is CW or CCS commands . would you give me more detailed description ？

[lunminliang]

Hello xuchao li,

May I know your CCS version?

In the CCS console window enter command

show version

You should see the version number in the CCS console window.

Hello xuchao li,

CW is CodeWarrior, CCS is CodeWarrior Connection Server, invoking from Start->All Programs->Freescale CodeWarrior->CW for XXX->CodeWarrior Connection Server.

So you have no problem to connect target?

Good to know, and thanks for sharing reason.

I use the edition of CodeWarrior  is  8.8,and my emulator is USB TAP.

Access the memoy of any space,like PCI、SDRAM、Flash,the data is same ,and if the address is end by 0x4,or by 0xc,like 0x0000_01024、0xFF00_000C,the data is all "00000000".if the address is end by 0x0,or ox8,the result is correct.So I conjecture that mybe USB TAP don't support the MPC8245 in 32-bit mode ?

The MPC8245 processor core has a selectable 32- or 64-bit data bus and a 32-bit address bus. See the Section 1.2.4 of the MPC8245 User’s Manual.

CodeWarrior 8.8 supports only 32-bit data bus.

CodeWarrior 8.6 supports 32-bit and 64-bit data bus. CodeWarrior 8.6 does not support USB TAP.

It is mistake in CodeWarrior 8.8.

Have a great day,

Pavel
