Hello, I'm back at development with Mini2440 after a few month of doing other things. When I try to run some projects that were working fine before, now those project won't deploy to the board, I've got this message : Quote: ------ Deploy started: Project: Mini2440_Sample_LED, Configuration: Debug Any CPU ------ All attempts to connect to the deployment target at port 5655 have failed. Addresses attempted: 169.254.101.217;fe80::2204:9ff:fe18:7%5;fe80::5efe:169.254.101.217%2;127.0.0.1. The device security configuration may have disallowed the connection. Ensure that you have the appropriate certificates on your device for development. Review your SDK documentation for proper security settings for connecting to this device. The same result for Visual C Or VB CF.NET projects. I think it has to do with Windows Mobile 6 SDK that I installed to develop with other PDA's. I've tried to "rapiconfig" security certificates, but I got errors. (probably works only for Windows Mobile) I'm using Visual Studio 2005 sp2. ActiveSync 4.5, English BSP image 5.0 from 2009. Here are the strange results: - My PCconnected fine to other PDA's which are also WinCE 5.0. - When I connect my mini2440 to another PC (active sync 4.1 without Win Mobile 6 SDK) it worked fine. Thanks.
