It took me a while to suss out the right connection between Blackcat and my M25P64 target. Hope this helps others. Biggest thing I missed was the slave-in/slave-out wiring: M25P64's MOSI to Blackcat's SO, and MISO to SI. Hold the M25P64's RESET pin to ground while programming.

BlackCatUSB --> Target (M25P64)
Pin 1 GND --> Target's GND
Pin 2 VCC --> (no connection, my board had its own 3.3V supply)
Pin 3 N.C. -->
Pin 4 SI --> SPI_MISO
Pin 5 N.C. -->
Pin 6 SO --> SPI_MOSI
Pin 7 RST --> /RESET
Pin 8 SCLK --> SCLK
Pin 9 PROG --> (no connection)
Pin 10 CS --> /FLASH_CS

How do you have your device connected , also do you realize you have posted this in a totally unrelated topic to your chip ??
 
Hi apologies problem resolved, chip need to be removed from board before programming( Pomona Clip Does not work) this due to the fact the there are resistors on the board that drop the 3.3V down to 1.6V , as the board is designed not to allow that and at the sometime after removing the chip you cannot use it again on the board will need a new one.
