USB_MSD_HOST_MQX_Lite_MKL25Z128_PEx invalid path,how to correct it in the right way?

diegocolombo — Mon, 10 Mar 2014 17:35:05 GMT

Please,i ask your help once again

I have to develop an application based on USB and MQX lite,the above example on FRDM-KL25Z board should help me a lot.

I read USBHOSTUG and AN4748 documents,but i'm still having some problems,likely related to the way project should be built,an issue that i don't master properly

After compilingm i have lot of warning,but the first i want to clear is:

Invalid project path: Include path not found (C:\Freescale\Freescale USB Stack v4.1.1\ProcessorExpert\Examples\Host\MSD\USB_MSD_HOST_MQX_Lite_MKL25Z128_PEx\Sources\common\kinetis).

I guess that i should copy or link the folder \common\kinetis in \Sources,but i dont know where to pick them from.

I searched in the USB stack folder for all the \common\kinetis occurencies,and i found one in

\Freescale USB Stack v4.1.1\Source\Host\examples,it contains lot of files,shurely some are not needed ,as the MK40 and MK60 .h files

but wich one are need, assuming that this folder is the right one?

Maybe should be better to copy the project in a workspace folder in a typical position satisfying the relative paths,but where?

Thanks for your help

Hi Diego

first please verify that the paths do exist in your PC. probably there is just a simple character that changes.

You must verify all the paths in:

menu Project > Properties > C/C++ Build > Settings > Compiler > Input

menu Project > Properties > C/C++ Build > Settings > Linker > Input

menu Project > Properties > C/C++ General > Paths and Symbols > C Source file

You must include here all that paths you are using and remove any path that does not exists in your PC.

After this please close CW. Go to your workspace folder and remove .metadata folder. Then reopen CW, reimport your project, clean your project and try again.

Have a great day,
Daniel

Hello Chen,thanks for your hints

i 'll try to answer to your question so to help you to help me.

first please verify that the paths do exist in your PC. probably there is just a simple character that changes.

this path does not exist in my PC,there is only one \USB_MSD_HOST_MQX_Lite_MKL25Z128_PEx folder,the one in the example,and it does not contains any

\common\kinetis folder.My question is; why that path appears in the include paths list of this example and then is not provided in the example?

You must verify all the paths in:

menu Project > Properties > C/C++ Build > Settings > Compiler > Input

menu Project > Properties > C/C++ Build > Settings > Linker > Input

menu Project > Properties > C/C++ General > Paths and Symbols > C Source file

You must include here all that paths you are using and remove any path that does not exists in your PC.

I'm just using the example as it is, i removed the non existing path ,anyway i have lot of warnings,as implicit declaration of function 'usb_class_mass_init,this because #include "usb_host_msd_bo.h" is missing where the function is requested.

Of course i can copy this directive in the code but i wonder why this is not done at compiler settings level.

I can modify the include paths, but i wonder why this operation is needed on paths realtive to the project folder,supposing that the example was working as it is on the pc of the one that developed it.

So i'm leaded to think that there is something wrong in the way i'm using the example

Thanks for your time and patience

Diego

If you just using the example as it is, not change anything, I think this example should be compiled without errors.

What you need to do is to import the projects. You can do this in 2 ways.

1) open your project folder in windows explorer and drag the .project file into CW workbench. then compile

2) Use menu File > Import > Existing project into workspace and select the folder where your project is contained.

Thanks Daniel,you are right

The example can be compiled .

What happens is that it works just partially:

Debugging it looks that the code stops in PE_ISR(Cpu_ivINT_Hard_Fault);

Makin it run ,the code performs various steps,but it looks that it restarts from reset,i wrote printf("PE_LL_init"); right after PE_low_level_init();

As you can see after "Test done!" it repeats the initial string.

PE_LL_init
