I Have been working with the MK3000 for a little while now and we are moving to the MK3100. We develop applications using vb.net in Visual Studio 2008. My issue is when we try to debug the code using activesync, I get a bootstrap error and it won't debug when connecting to the MK3100. Using the same code the MK3000 works fine. I have downloaded EMDK 2.7 and downloaded the WCE7 hotfixes for VS. Any suggestions on what I need to do to get past the bootstrap error? There was another post for another terminal where they talked about installing a PSDK for the unit, but I don't see anything for the MK3100.
