I am having the same issue with the system hanging when enabling the file system as reported by another user. I am wondering if there are any known issues/limitations with using the native file system on connectme -c modules with jtag(95010428D). I installed all available updates, set BSP_INCLUDE_FILESYSTEM_FOR_CLIBRARY to true, added libfilesys to the application make file and rebuilt the BSP and application. Stepping through the filesystem_init calls while running the debugger does not produce any errors. However, as soon as I flash the application and attempt to run the system hangs. It appears the file system initialization fails with a fatal error. This happens with the example application as well. If I disable the filesystem flag, rebuild and flash the application it runs, but I am in need of the file system.
