Mind you, all of that seems like a workaround. Removing functionality just to fit the monster with DM/DT in is a no-go. R-Car Gen2 doesn't use DM/DT in SPL because it just won't fit and I believe that absolutely makes sense ; why should we impose DM/DT in SPL on MX6 only to make it less usable? -- Best regards, Marek Vasut
