MCB2300 SD Card Error

[NicB]

These are good news: MCB2300 support files.

However, Jaggs got IO errors, so I don't know if those identified are the "main problems".

1.Of course, the second Open/Replace should be wired to the output of Close File in order to be sure the file opened for writing is closed and then reopened for reading (http://forums.ni.com/ni/board/message?board.id=420&message.id=1455#M1455).

But this is not the case - the generated code does the right thing in this case (open-write-close, open-read-close). Sometimes is no, and fortunately, you don't need an "ultimate solution" here.

2.M:\ is the default drive/path and is concatenated automatically. It would be to easy.

Hello All,

I was still not able to write through the LabVIEW embedded to the SD card.  I always get error 6 or 7.  However, I was able to run the Keil SD card example in uvision and then read/write through the hyper terminal.

Thanks.

finally got it solved by using finit(); and small delay functions.  Please see the attached picture.  Thanks NiCB for suggesting it.
