MCB2300 SD Card Error

[Jaggs]

Hello Application Engineers, Any Ideas??

[NicB]

If you can read and write files from Hyperterminal using Keil example then you should be able to make the same from LabVIEW generated projects (there is not a hardware issue).

Let's try something, even if that issue had been already fixed: use UPPERCASE.TXT filename.

I don't have a MCB board, so inviting application engineers is a good idea. Could you update all project, including generated files (remove MCB2300\Application\2.0\Project\Obj before making the archive)

[NicB]

Sorry, my suggestion was to upload (post here) an archive of your project folder. Removing the Obj folder will reduce the size.

[NicB]

Here it is my generated files.

Open project sd card\tst sd card\MCB2300\Application\2.0\Project\LabVIEW.uv2 and try flash-download-debug.

Hello NIcB,

I have changed the name to all caps but it did not work.  I directly flashed the project send  by you and it did not work.  Please find the attached project which I recompiled.  Please let me know if you can flash the project file which I compiled.

This is my uvision version which is evaluation version.

I understand you are seeing the same errors (2-IOerr) in RTAgent window while debugging the project posted by me (so, there is no DAVID.TXT file in your SD). However, I checked the files and versions from your archive and seemed to be OK.

Again, I don't have a MCB board so I cannot help with real tests (be sure, the problem would be fixed already if I've had one).

I am very thrilled:

- Meghan said she tested files on MCB2300,

- you don't have hardware problems (because Keil demo run successfully),

- and your system is properly configured, generating the same code as mine.

Who's lying here?

Also, all is working well on Stellaris, and the only differences are drivers (MCI_LPC23xx.c) and library (FS_ARM_L.lib - yes, you can build the SD file demo from Keil because the missing file is in your computer : ).

This is the link from where I downloaded LabVIEW embedded 2009:

Can you please check if this is the correct version..

[NicB]

Yes, it is.
As I wrote in the previous post I checked your generated files, project and drivers and all is OK (this explains somehow why my project is not running successfully on your board).

Hello Jaggs,

I could succesfully run the snippet example that was posted earlier in this thread.  One of the main problems I saw in your example was that you need to wire the path output of the first close to the input of the second open/create/replace function.  This will ensure that you are creating and succesfully closing the file before trying to read it.

 One thing you could try is to make the file path M:\DAVID.TXT.

Also I have posted a zip file of my directory minus the Obj folder
