Comment:

 Jerry gives the following procedure.  I (Mitch) tried it and it works, so
 I'm closing this ticket.

 The reset procedure:

 Each function can be reset by using the global register at 0x3034

 Bit 0: NAND soft reset Bit 1: SD soft reset Bit 2: Camera soft reset

 So for NAND reset:

 Write 0x1 to register at 0x3034 Write 0x0 to register at 0x3034

 Updated data sheet will be release to you tomorrow.
