Hi Peter,


Thanks.  I looked at the connections shown for the 20 pin and also have the one from the eLinux org for the SPI connector.  Later today or tomorrow I will see if I can match signals.


David Anders also replied and is looking into it.

Documentation (such as http://www.elinux.org/Minnowboard:SPI_Boot_flash) indicates that the Minnowboad flash can be programmed using the TinCanTools Flyswatter2.  But I have been unable to find either a schematic or actual cable to connect from the Flyswatter 20 pin JTAG connector to the Minnowboard 8 pin SPI connector (or even determine if those are the right connectors to use).  Can anyone point me in the right direction?
