Hello,

you have several options:

a) disable linker message

add -WmsgSd1100 to your linker options

b) use defines like this

#define VAR_ADDRESS 0x1880unsigned char var @VAR_ADDRESS;#define v1 (*((unsigned char*)VAR_ADDRESS))#define v2 (*((unsigned char*)VAR_ADDRESS))

hope this helps,

I am so appreciate your repay. Thank you very much.

could you please kindle provide more information about :

"a) disable linker message

add -WmsgSd1100 to your linker options"

I am a new hand in using CW. I don't know how to "disable linker message" .

is it a option in the CW setting? or I have to add -WmsgSd1100 into my source?

Please please tell me the detail steps to disable the linker message. Thanks a lot.

Hello,

sure thing.

Select the project, then use the menu Project > Properties.

Then see attached screenshot.

Hope this helps,

PS: Screenshot is from MCU10.2. MCU10.0 is really old, I suggest that you are using 10.2 instead. But options should be the same.

Hello,

Another possibility may be to define v2 as an alias for v1, within the file that uses v2. Personally, I do not like to disable error messages that may hide an important coding error elsewhere in the code.

#define v2 v1 // v2 is an alias for v1

Hello,

Thanks for your patient reply.

I am using CW10.0. And my setting interface is different from yours.

Please help to check if the setting is correct. (see the attached pic)

I check the" disable user message" and add the "WmsgSd1100" into the rectangle.

Another question: I click "check update" and a pop dialoge said:' There are no update sites to search. Do you wish to open the "Available Software Sites" preferences.

Hello,

on upgrading to 10.2:

You cannot upgrade from 10.0 to 10.x from within eclipse/CodeWarrior.

The update you tried only applies for service packs and fixes.

To get MCU10.2 you need to download it from here:

http://www.freescale.com/cwmcu10

You still can keep your current installation (no need to uninstall).

Hope this helps,

Hello,

about the linker option: add it to the 'other flags' in MCU10 prior 10.2 (see attached screenshot).

Re: How to Remap...

Hello.

Does it mean I have to add -WmsgSD1100 to two places?

(1) Poject -> Properties -> C/C++Build ->Setting -> Message: check Disable user message, add -WmsgSD1100 into other falg rectangle.

(2) Poject -> Properties -> C/C++Build ->Setting -> Linker -> General -> add -WmsgSD1100 into other falg rectangle.

more question: I found there is a "-WmsgFob"%f%e:%l:%k..."exist the "other falg rectangle"

what's that ? Can i delete it ?

Hello,

add it only once, into the linker settings.

And keep the other options like "-WmsgFob"%f%e:%l:%k..." (this one formats the error messages, see the description in the manual).
