Compiling source for LPC1837 Explorer

Hi,

Received my LPC1837 Explorer today and am having trouble compiling the demo sources.

I set up a new workspace and perform the steps listed in the users guide for LPCXpresso v6 ( I have v7.5.0 ).  When I build all, I get a yellow warning stating "Invalid project path: Referenced project is not accessible".
There appears to be no additional info to go on.  I have experimented for a couple of hours but have succeed only in making it worse.  The error is only on the
project: ngx_xplorer_1830_lpcusblib_DualDeviceAudioMSC.  The other two projects appear to compile OK.  I am guessing that the error is more serious than a simple warning so I want to get to the bottom of this.

I am thinking that the import process must be slightly different for the new version of LPCXpresso but I have not been able to guess how.

My installation of LPCXpresso is pretty vanilla, newly installed before the holidays.


Thanks,
Tony

I am able to do that now... :)

I have created work space in root directory and copied the USB demo code also in same root directory.
If you import the code after this it will work...

Thanks

The following are the two elements with the warnings in the project that came with the board...

(1)
ngx_xplorer_1830_lpcusblib_DualDeviceAudioMSC->Paths and Symbols->Libraries

lpc18xx_ngx_xplorer_1830_board_lib
ngx_xplorer_1830_usblib_hostdevice


(2)
ngx_xplorer_1830_lpcusblib_DualDeviceAudioMSC->Paths and Symbols->Libraries->Library Paths

../../ngx_xplorer_1830/ngx_xplorer_1830_board_lib/Debug
../../ngx_xplorer_1830/ngx_xplorer_1830_usblib_hostdevice/Debug


Please indicate what they should be so that there will not be a warning.


Thanks

I was not sure if I understood what the Quickstart wanted for the source directory so I went back and selected the following...  but first I created a directory in the root of my drive E.  Got rid of some directory depth and special characters in the directory name.    I now have E:\LPC1837\DemoSource for the unziped demo code and  E:\LPC1837\WS for my workspace.

This is the root directory that I selected when importing.

E:\LPC1837\DemoSource\applications\lpc18xx_43xx\xpresso_projects


After importing, I select Project->buildall and get the same warning.


I notice that some of the images in the Quickstart PDF show warnings too.  ( but missing library looks too serious to ignore )

Thanks

Hi again,

I tried following the Quickstart you suggested.  It appears to the the same procedure that I followed except they give a little more detail on selecting the source directory. 

I unzipped "USBDemos.zip" from the SD card and placed it in a directory I called "UnzippedDemo".  When I imported I selected the following location: E:\!Datexch\UnzippedDemo\applications\lpc18xx_43xx as the root directory.  The expected three projects imported.

I left the build configuration set to "debug" and built just project that I am having trouble with.  Same yellow warning.


Thanks

Looks like our postings crossed... I will look at your suggested link for V2.

OK the link is the same as my SD contents so when I compiled, I get the same problem.

The link contains the source to the image that is installed on the Xplorer board.  Inside the link is a pdf file "LPC1837 explorer board".  On page 6 there are step by step instructions for building the demos / source.
When I follow these instructions, three projects are imported into my workspace.  The 2nd project which I will call "audioMSC" (for brevity) is where the problem occurs.

When I perform step 7 in the PDF,  "Build All",  a yellow warning indicator appears in the Project Explorer tab in LPCXpresso.
The problem "Invalid project path: Referenced project is not accessible." appears in the Problem tab in LPCXpresso.  There is no other info displayed.  If I expand the project in the Project Explorer tab, none of the sub objects have warnings or errors.

I right click on the audioMSC project and choose properties.
I expand the C/C++ General property.
I choose the Librarys tab,  There is a warning on each of the items in this tab.
I also choose Library Paths tab.  There is a warning on each of the items here too.

I have expanded all of the other properties for the audioMSC project and find no additional warnings.

It seems that the problem I am having should be fairly easy to tie down.  But all of the things I have tried so far changing the library properties have resulted in red errors.  So I am asking for help.

Thanks

From a very quick look at this ZIP, this example bundle appears to be based on LPCOpen v1, not v2. This means that the way you need to load the projects into LPCXpresso is different. In the first place, please see:

http://docs.lpcware.com/lpcopen/v1.03/_q_u_i_c_k_s_t_a_r_t__l_p_c_o_p_e_n__t_o_o_l_c_h_a_i_n__x_p_r_...

You should also be aware, from what you say, that you have a board with an LPC1837 fitted, not the LPC1830 that these examples appear to have been produced for. ie you have a part with internal flash.

Regards,
LPCXpresso Support

Hi,

My copy came right from the SD card that shipped with my board.

I have also found the project on NXP. 
http://www.lpcware.com/system/files/MicroSD%20card.zip


I am going to try working with that to see if anything is different.
Will update this post either with good news or more detail about what is happening.

Thanks

Where did you download the examples from? Please post the link
