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,
because i do not have a full version of uvision my debugger doesnÂ't work (totally).
At least that is what uvision says to me when i start a debug session.
I am pretty new to uvision and arm processors so you have to break everything in little steps for me.
I am sorry for that! I am trying to learn but uvision doesnÂ't want to work with me!! :)
Thanks for your patients!
maybe you can give some indication using a LED what your software is doing, or if it caused an exception of some kind? you can place an infinite loop in any exception handler, then send out a message using a UART, blink a LED as mentioned above, beep etc.....
I tried to load blinky. This is a example project that was deliverd with the evalbord.
But the LED doesnt blink!
So i think i have to give a starting adress for programming or the creating of the bin file is not going well.
a long shot, I know: have you verified that the memory layout of the demo project matches the memory on your board...?
have you setup the flash correctly as Per suggested? what eval board are you using?
it is a odd problem.
post the project files and all the code here and we will check it for you.
I dont know what Per meant so i did not do that.
You can find all the project files on this website:
www.circuitcellar.com/.../12.html
I use the EKK-LM3S811 evalbord.
The blinky project has done it, but i do not know what i have changed.
If you want i can also post the blinky project.
Thanks already!
open your 'project->options for target' dialog. then click the utilities tab, then click the settings button (for flash programming). there you will be able add flash algorithms for your specific target. without that no flash operation can succeed!
Marleen, It is so incredibly refreshing to have a woman here among us droogs (assuming of course you are indeed one...). Hell the last woman I saw here was ms. embedded and something tell me she was as hairy as a bear....
you assumed right!
and you (the most here) are not that bad! I learned a lot here from you guys
Marleen. I am happie we can help you :)
I tried to add flash algorithm but that is not possible. I use luminary eval board.
I can not use ULINK because i do not have a cable for that. And i have the same problem with JTAG. Than there are two more options; RDI interface driver and luminary eval board.
I can also use the flash programmer from luminary micro but that doesnt work. I have the same problem there.
well, if you cannot add a flash algorithm, you are unlikely to have your software uploaded correctly. but why not? I see your device in uv's list of flash devices available to me (I'm using 3.20). have you selected the correct target driver for flash programming ("configure flash menu command" menu)
Hello Tamir,
i do not understand you totally. But i selected the right target (LM3S811). I do not know how to select the correct target driver, maybe you can expend more about this?
I am afraid that my problem lies in having a eval mode.
As flash programmer i now have luminary eval board standing. unfortunaly i can not do any settings here.
Can i put a picture in this forum, so i can show you a screenshot??
Hello Marleen,
Yes, I see what you mean. I just tried to follow my previous advise with your board selected as target - to no avail. The information message here advises me to visit http://www.luminarymicro.com/. Maybe you can find your answer there?
