The error codes that come back in newtmgr responses are always (or at least should be) MGMT_ERR codes: https://github.com/apache/mynewt-core/blob/42bb5acc2f049d346c81f25e8c354bc3c6afefd4/mgmt/mgmt/include/mgmt/mgmt.h#L65 `MGMT_ERR_ENOENT` is indicated when the newtmgr command isn't recognized (it is also used for other conditions; seems like we should have a dedicated error code for "command not supported). Did you enable the `FS_NMGR` syscfg setting? Chris
