Hi,

I do not know which type of the MCU you use so I have attached two examples.

There is, I think, detailed description how to use variables. I would like to direct your attention to a text:

/*
Notes:
- Look at compiler command line which has to contain -D__FAR_DATA option
because there is note in the Start12.c file at the line 40
- It is also good to think about next compiler option __BANKED_COPY_DOWN;
line 49 in the Start12.c
- variable eee is not processed correctly because it missing "far" in the variable
definition
notes:
    - I advise to step the code within simulator to better understand how it works.
    - During simulation; Drag and drop the variable from "Data:1" window to
      Memory window to find variables within memory
*/

I hope, it will help you.

If this does not answer your question(s), or I have forgotten something, or if you need more assistance, please contact me again.

If the answer is helpful, please label it.

Best regards,

Ladislav

Dear Lama：

thanks for your reply.

but the question what occur to me is when I debug my project the IDE told warning L1128. your reply let me know the reason of the warning is FAR_DATA is not defined.

but I still dont now why does the FAR_DATA couldnt be defind.

last day I have asked the question "How to use PE to initialize Xgate",a good man tell me Codewarrior dont support this function. so I use PE to build a project and disable pe create the prm file ,transplant a prm which is from a projct could use Xgate to handle interrupt. when i finish that,all the function could be used , the interrupt could be handle by Xgate too(although the debugger of Xgate couldnt use ).

but the warning L1128 occur. I find the FAR_DATA have not been defined in start12.h.(But another project's FAR_DATA has been defined )

why does the criterion doesn't go though?

my IDE is codewarrior IDE 5.1 the MCU is mc9s12xet256maa

look forward your reply

best wish.

Hi,

I am sorry for delay because of vacation.

I do not suggest to combine PE and own project. I am saying this from my experience. I have used PE only to check how the "expert" solves some setups. I like to have everything under my control so I newer use PE in my projects. There are a lot of features in PE I hate.

So back to the issue.

Is it possible to send me project you use. I would like to check the behavior on my PC. The only thing I would ask you to be all paths and files related to project pointed/placed in the project folder.

If the project is confidential I would like to ask you to create a case and write into subject "To Ladislav"

The procedure, how to create a case is described:

Hi,

is still a problem alive?

If yes, just create a service request and introduce it "For Ladislav".
