Read From Binary File doesn´t work on MCB2400 in LV2009 Embedded ARM

[aminat]

Hello,

I try to read a Binary File from SD-Card on my MCB2400 Board with LV2009 Embedded for ARM.

But the output is always 0, if I use my VI on the MCB2400. If use the same VI on the PC it works fine with the same binary file.

The access to the SD-Card on the MCB2400 works in other cases finde, if I try to read from a text-file it works without any problems.

Are thre any constraints for the "Read From Binary File"-Node in Embedded in comparison to the same node on PC ?

bye & thanks

Now I have noticed that there is also a problem with the reading of textfiles. If the sice of the file is about 100Byte it doesn´t work anymore, too. I can´t understand it, because I read always just one Byte. And even if the implementation in Labview is so bad that it allways reads the total file in the ram it sould work. The MCB2400 has 32MegaByte RAM, so 100Byte or even a few MegaByte should work.

But this doesn´t seem to be the Problem for the Binary-Problem. Because even a 50byte Binary-File doesn´t work.

Your problem has nothing to do with instrument control. You'll probably have a better chance of getting your question answered if you post it to the LabVIEW Embedded board.
