MPC55xx:How to create my own initialization file?

[Ian92]

Hi,

   I just setup my USBTAP connected with my board.  Now I am trying to flash my u-boot.bin to the flash but still have trouble until now.  I have added my own flash config and select the PQ27e_init.cfg as the Target Configutaion file.  However, when I begin to erase the flash it ends up with a failure message and below message I dumped from the logfile.

======================================================================

I am wondering if I need to create a customized Target Initialization file instead of using the PQ27e_init.cfg.  Is there any help or document I can obtain? Plz help! Thanks.

Below is my test environment:

Board: MPC8247, 128MB SDRAM

IDE: CodeWarrior IDE version 5.7.0 build 1917(CW_EPPC_2.6_Build_60213), USBTAP ROHS updated

OS: Fedora Core4

Hello

Did  you check "Troubleshooting the CodeWarrior Flash Programmer " that you can find in the CodeWarrior EPPC web page

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=CWS-PPC-CMWFL-CX?

Hi,

  Thanks for the reply.  I have looked into the document you mentioned, but I think the problem is raised by the wrong Initialization files.  Since my board is not an evaluation board and I must do some modifications on the example files or create a custom one .

 So my real problem is how this file generated,  how to set those memory register correctly.  Thank you!

Hello

Initialization file is not generated automatically. We have some sample initialization file available in {Install}\PowerPC_EABI_Support\Initialization_Files and its sub-directories.

If your own board does not match the delivered ones, you have to create your own file.

Syntax of the command in a debug initialization file can be found in Targeting Embedded PowerPC.pdf manual.

Take a look at chapter "Debug Initialization Files"

Basically this file should set up all board and on-chip configuration registers to allow you to connect to the board and access the memory.

Hi,

I have a simillar issue with two of the boards I'm working on. I'm using MPC5554. These two boards (not evaluation boards btw) were working perfectly fine up to couple of hours ago when I tried erasing the whole memory map and reprogramming part of flash. First I tried easing the whole memory map when Flash Programmer Tool got stalled (Erasing ...) and never completed the task. After cancelling the Erase Command I have not been able to neither erase nor reprogramm any one of these two boards.

The following is Log mesage which I get everytime I try to Erase:

I am running out of pcb boards and time.

Thanks,

hi,
        Even i am having the same problem. If anyone have solved it please guide me also. I am using MPC8247 processor with Codewarrior usb tab emulator. I am stuck in the initializtion files only. Any tutorials on "how to make the config files", please send me the link.
