I have most of my embedded system living on the disk (a little bit of ramdisk for root, and tmpfs for /tmp) with not a spot of trouble. I have noticed that if the disk does not have a .ace file on it, and a Xilinx chip to program, the driver fails to get any partition info from the disk and it all fails from there. So I suspect the driver still to some degree relies on the state of the chip after a successful Xilinx load. If you are trying to use the chip without an FPGA attached, you may be running into that. -- Steve Williams "The woods are lovely, dark and deep. steve at XXXXXXXXXX But I have promises to keep, http://www.XXXXXXXXXX and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep." ** Sent via the linuxppc-embedded mail list.
