The ADSP-CM40x Enablement Package (Rev. 2.1.0) software supports only the board revisions stated in the Release Notes and the ADSP-CM40xF device silicon revision H. It does NOT support silicon revisions prior to H; therefore, it must NOT be used in development efforts on older silicon revisions.
The silicon revision is branded on line #3 of the ADSP-CM40xF product package, directly after the lot identification number (e.g., 1234567.1-H indicates that the device is revision H silicon from lot number 1234567.1).
