Issue Date Affected More Information
External Crystal Layout Error 2010/04/14 EVAL-04 Boards shipped before 2010/04/14 Some EVAL-04 RevC boards have an error in the layout and the decoupling capacitors for the external crystal are not tied to ground. All boards sold after 2010/04/14 do not have this problem. This error only affects use of an external crystal. Please contact us for repair replacement information.
