How to read memory using CodeWarrior TAP/CW for PowerQUICC w/o source/executable.

gschmick — Fri, 24 Jun 2016 14:25:08 GMT

I have an MPC8280-based system with a convoluted build process I haven't figures out yet. I'd like to use my CodeWarrior TAP, driven by CodeWarrior for PowerQUICC 8.8, first to just read the contents of RAM and flash, and I don't see how to do that. Any suggestions?

Hello Grant Schmick,

Please follow new project wizards to create a bare board project for MPC8280 platform, then modify the initiation file in C:\Program Files (x86)\Freescale\CodeWarrior PA V8.8\PowerPC_EABI_Support\Initialization_Files\PQ2 according to your target board.

Connect CodeWarrior to the target board from Debug->Connect, then read RAM memory from Debug->EPPC->Load/Save Memory.

Have a great day,
Yiping

Dear Yiping,

Thanks for the advice. I tried this, got thru the wizard but there was no mention of the initialization file, so I'm not sure how it's specified. Do I have to create one with the name of my project? Also, looking at the examples, it's not clear what may be needed in my init file. Any advice or reference I can read?

Anyway, I tried the Load/Save Memory dialog, but the "OK" button stayed grayed out, though I think I used a valid address (flash). any thoughts?

Thanks,

Grant

Hello Grant,

You could specify the initialization file from Edit->Debug Version Setting->Debugger->EPPC Debugger Setting->Use Target Initialization. CodeWarrior initialization files for MPC8280 are located in C:\Program Files (x86)\Freescale\CodeWarrior PA V8.8\PowerPC_EABI_Support\Initialization_Files\PQ2, you could choose one porting for your board, please check the section "Setup the chip selects".

After CodeWarrior connects to the target board from Debug->Connect, "Load/Save Memory" would be available in CodeWarrior IDE.

Have a great day,
Yiping

Hi. how to read Nand-flash dump? and how to write it to another board with the same processor and memory chip?
