program faulr?

Marleen ten Broeke

Hello,

I'm (still) working on a project with the LM3S811.
At first i had some problems with the compiler in uVision but that is solved now!

Now i have a different problem, when i load my project i to the memory uvision says it is done, but when i reset the evalboard it does nothing!
I also did this with a example project, same problem!

I also tried to load the file with luminary micro flash programmer but i have the same problem.
When i load a .bin file that i know is good it does work!
So programming is going oke, but i think the problem lies in creating a .bin file.

I do this in uVision by putting the following line in a user command (after build);

C:/Keil/ARM/BIN31/fromelf.exe --output blinky.bin --bin blinky.axf

can anybody tell me what i am doing wrong??

Thanks,

    Oke, yesterday i had some problems with uvision but afer re-installing it a couple of timeÂ's it is working again!

    The blinky project is now working.

    But when re-build my project i get an error.
    I do not know what the problem is, Maybe you guys can help?

    This is the error:

    Build target Target1
..
Linking...
Cortex=project.axf: Error: L6218E: Undefined symbol I2CMasterInitExpClk (reffer from osram96x16.o)
Target not created

    The osram file is for the oLED display on my board.
    I saw a older post on this topic but it wasnÂ't solved (and it was a different board).

    Does anybody know of this problem?

    Undefined symbol I2CMasterInitExpClk (reffer from osram96x16.o)

    Two things:

    1) please don't re-type error messages. Copy-pasting them avoids typos like the above "reffer" instead of "referred".

    2) That's a pretty clear error message. The module osram96x16 calls a function or uses a variable, named "I2CMasterInitExpClk", which doesn't exist anywhere in the code you told the linker to process. Find it and put it into the project.

    Hello,

    Thanks for all the help!

    it is working now!!

    I needed the latest driverlib.
    When I installed these and changed the directory (in uVision) it worked!

    So now i need to study the code and find out how i can let the project speak dutch! and inprove the quality of the voice.

    Thanks for the help i gave me a lot of new ideas.
