Hi Wan,
Again, I ask you to send all questions to the mailing list.
Not only do you access a greater pool of expertise in that
manner, but also at least you are able to contribute to the
collaboration by bringing problems and their potential
solutions to light.
The most probable issue is that your bitstream is incompatible
with the board. Are you compiling your design for the ROACH
SX95T platform? ROACH prototypes were built with LX110T devices,
whereas the shipping production versions have SX95T. The option
is available from the XSG Core Config block platform dropdown menu.
The other possibility is that the kernel you have on the board
is outdated and doesn't yet support the differences in the bitstream
it has to download to the FPGA. You may need to recompile the
kernel you have for your board. Instructions for obtaining and
building the kernel can be found here:

Hi Henry:
I can boot the Debian core from external USB stick. But it seems that
the bitstream could not be loaded correctly. When I execute the bof
file, I receive a input/output error.
Please see the following dmesg error information. It seems that the FPGA
configure done pin could not been asserted. That means the FPGA
configuration is failed.
