<DIV><SPAN class=068485119-28082006><FONT face=Arial size=2>Hey
guys,<BR><BR>I've run through the loops to try and figure what could be wrong
with this system. The board in question is modeled after the Xilinx ML300 board.
It uses a Xilinx System ACE chip to load a FPGA / Kernel image from compact
flash. Originally, I was trying to use the CompactFlash as the root file system,
but because of issues in either the design or software, this would only work if
SysAce was in polled I/O mode. To circumvent this, I built my root filesystem
into an initrd image and built a single ELF file with the Kernel and RFS, then
strapped that to the FPGA bit file to make a single FPGA/Kernel/RFS SysAce
file.<BR><BR>Upon decompression, the Linux kernel boots quickly and loads all of
the device drivers. However when it gets to the prompt, it starts slowing down.
Output and input to and from the board becomes very very slow (it displays 2
characters roughly every 20 seconds). Originally I believed this to be the CPU
still polling SystemAce, so I disabled the Linux System ACE drivers to remove
that as a possibility, however after doing this, the problem still persists,
even with the RFS in ram! Has anybody encountered a similar situation to this
before, with possible insight towards a solution? Thank you for your
time.</FONT></SPAN></DIV>
