One thing you might want to look at is the *OTHER* ways you can use the FTDI 2232 chip (a very common jtag solution that openocd supports). One of its other modes is an SPI programmer mode. See this: http://www.ftdichip.com/Projects/MPSSE.htm#SPI I think it would be very beneficial for OPENOCD - if somebody was to create an alternate way of using OPENOCD - to program SPI chips - via some type of "direct connection" - like the XILINX impact program supports. Nothing says the only way is FTDI - for example - the simple bit-bang parallel port solutions would do the same thing. I just think adding this feature to OpenOCD would be a very helpful thing! I think the I2C mode would be nice - but SPI is perhaps more important. Specifically: The XILINX impact program can do exactly this. See this example: http://www.xilinx.com/support/documentation/application_notes/xapp951.pdf Page 4 - shows *TWO* different connectors - (1) JTAG connector (talking to the jtag pins on the xilinx) and (2) a SPI connector on the xilinux -> to -> spi interface. There are *two* ways of programing the spi (1) indirectly via jtag - through the xilinux - (ie: the jtag connector) or (2) via the spi connector. I am speaking about the SPI connector method. I know the DLC5 xilinx cable will do that. I have used exactly Impact + DLC5 + SPI FLASH to configure FPGAs. Perhaps - maybe it is too late - but do you have a few "bed-of-nails" targets on your boards you are making? -Duane. _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
