Embedded ethernet kit resets

I seem to be getting alot of resets in MACGetHeader, has anyone else seen this or have any ideas?

Code:

// such as if a single SPI bit error occurs while communicating or a
// momentary power glitch could cause this to occur in rare circumstances.
if(header.NextPacketPointer > RXSTOP || ((BYTE_VAL*)(&header.NextPacketPointer))->bits.b0 ||
header.StatusVector.bits.Zero ||
header.StatusVector.bits.CRCError ||
header.StatusVector.bits.ByteCount > 1518 ||
!header.StatusVector.bits.ReceiveOk)
{
//Reset();
printf("RESET CPU\r\n");
reset_cpu();
}

Add a printf statement (or statements) to display all those values in the if() statement. Then you can see which one is causing the problem.

Code:

Last Reset = 12
header.StatusVector.bits.CRCError
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
((BYTE_VAL*)(&header.NextPacketPointer))->bits.b0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
header.StatusVector.bits.ByteCount > 1518
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
header.NextPacketPointer > RXSTOP
header.StatusVector.bits.Zero
header.StatusVector.bits.ByteCount > 1518

Last Reset = 0
((BYTE_VAL*)(&header.NextPacketPointer))->bits.b0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
header.NextPacketPointer > RXSTOP
header.StatusVector.bits.Zero
header.StatusVector.bits.ByteCount > 1518

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
((BYTE_VAL*)(&header.NextPacketPointer))->bits.b0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
!header.StatusVector.bits.ReceiveOk

Last Reset = 0
header.StatusVector.bits.ByteCount > 1518
!header.StatusVector.bits.ReceiveOk

Last Reset = 0

seems like a bit of all of them are triggering
