AT45DB642D says 0x0B is fast (up to 66mhz) while 0x03 (up to 33mhz) And ...041B, ...081B, ...161B, ...321, ...321C, and others don't. (From a quick scan of datasheets I have locally...) Those 0x0B and 0x03 commands are "new", and have never been used by the Linux DataFlash drivers. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
