Open source cable server for Xilinx - for remote running of tools like Chipscope with unsopported target - wzab - 2012-01-26 02:43:00

Hi,

II'd like to know if there exists an open source implementation of
Xilinx cable server, allowing to run it on a platform for which Xilinx
does not provide binaries.

Of course it is possible to implement it as e.g. remote parport device
(as Xilinx tools support parport connected programmers on Linux
platform), but this solution would probably suffer the performance
penalty.

Another solution would be to split the linux open source driver
( http://rmdir.de/~michael/xilinx/ ) into two parts communicating via
TCP/IP, as I suggested in my post to comp.arch.embedded "Crazy idea -
Embedded PC + USB debugging with QEMU - passing of only one USB
interface to QEMU, or distributed libusb-driver" (
http://groups.google.com/group/comp.arch.embedded/browse_thread/thread/7e425d14fefb20fa/af
9623faf7f48f66
).

Both however are suboptimal solutions. The most efficient would be
simply to have functional replacement of cse_server running on remote
embedded system connected to the debugged FPGA.

Has anyone tried to do this? Does anybody know if the cse_server
protocol is documented?

I've found the old post:
http://www.fpgarelated.com/usenet/fpga/show/51158-1.php
pointing to http://sourceforge.net/projects/xilprg/
I've not verified it yet with hardware, but after first look it seems
to be a good point to start.

Xilinx changed there cableserver API, so xilprog doesn't work any longer
with recent versions.

For remote system capable to be USB host and to
run Linux a good
solution may be to use usbip: http://usbip.sf.net
(via VPN if connection goes through a public network).
Then both ChipScope and driver runs on developer's machine, and only
USB requests/responses are forwarded via network.
I have yet to evaluate the performance of such solution.
