SD card program problem


#1

I copied the SD card example from Beginners guide to NETMF 22.1. SD Cards to build a Console App for my FEZ Domino.
But the device seems not working with the app. The debugger ended automatically.
Then I commented all code in the Main() and left an endless loop, but It was still not working.
If I remove the additional DLLs for reading SD card, the app worked.
What’s the problem? Does it relate to DLL?


#2

Make sure your references to the correct DLL’s are there.
Sometimes removing the reference and re-referencing will fix the problem.

Look at the big notice on the right about updating firmeare :wink: the note is in the book too :slight_smile:


#4

I found that the problem relates to GHIElectronics.NETMF.IO.dll
If I add this, the program will not work.
But I really need PersistentStorage class, which is defined in GHIElectronics.NETMF.IO.dll
What 's the problem??


#5

I already told what the problem is. Please update your firmware


#6

I have the same problem (just got a domino and have been working through the beginner book) and It does appear that my firmware is out of date (.2 vs .3), but I’m not finding instructions on how to actually update the firmware though.

It’s late in the day so maybe i’m just missing something obvious.
