Method Detail

nativeWriteBackPE

public int nativeWriteBackPE(int peNum,
                             byte[] bitstream)

This method takes a core readback bitstream in a byte array format. The byte array must be allocated before being passed in as a parameter.

Parameters:

peNum - This indicates the number of the PE which is to be readback. The numbering of PEs used by the ReadBackManager and ReadBackData objects starts with zero.

bitstream - The array of bytes which is filled with the bitstream information. The length of the bitstream array is determined by the ReadBackData object via the ReadBackPEType object retrieved via nativePEType.

Returns:

The method should return RB_FAILURE if the operation failed, otherwise, RB_SUCCESS should be returned.
