Re: [reconos-devel] ReconOS - ZYNQ port availabe ?
Dear Anup, sorry for the late reply. In fact, as far as I am aware, there is work going on to port ReconOS to the Zynq platform at the University of Paderborn. It is not yet part of the github tree, though. In what area/application do you plan to apply ReconOS on Zynq?

Re: [reconos-devel] Error : "usr/bin/env : python : No such file or directory"
Dear Trong Tuan, I wasn't even aware that ReconOS has ever been deployed on a Spartan3 board; the only supported platforms I am aware of are the Xilinx ML405 (Virtex 4), the Xilinx XUP (Virtex 2 Pro), and perhaps an Xilinx ML605 (Virtex 6). Perhaps someone from the more active ReconOS developers can comment on this? ;) Is there a Spartan3 board definition for eCos in the ReconOS repository?

Dear Tuan, the make script fails while running platgen; could you send me (or post to the list) the relevant section of the file "make.log"? It should be in the same directory you started make in.

Re: [reconos-devel] Error : "usr/bin/env : python : No such file or directory"
Dear Tuan,, please excuse the delayed response. If "make netlist-static" works fine (congratulations for getting that up and running!), it appears that you have a valid Python toolchain installed. This may have been part of the standard Fedora install. As far as I know, there are no plans to support the ReconOS build chain on WindowsXP, which would require significant effort with little added benefit. Both the Linux and the eCos host operating systems are way easier to build on Linux; the same is true for the hardware tool chain. I'm not even sure if you can easily build an eCos application/OS image with a compiler other than gcc. I'd therefore strongly recommend to use Linux for the ReconOS-specific parts of your application.

Re: [reconos-devel] Error : "usr/bin/env : python : No such file or directory"
Dear Tuan, the ReconOS toolchain ist built for use on a Linux system. While it may theoretically be possible to use a Windows system with CygWin (that's what the Xilinx tools come with on Windows, I assume), I'd strongly recommend you try it on Linux first (e.g., in a virtual machine).

Re: [reconos-devel] Partial reconfiguration - first success on ML605
Hi Ariane, 2. OSIF interface logic: For point two: Are you thinking about just redefining the busmacros (as suggested in some xilinx documentation) or would you re-write the actual osif code? Probably the latter. Though timing is always a possible issue, I suggest that we first just replicate the 'enable' functionality of the bus macros within the OSIF and leave the additional register stages for later. The ML605/Virtex-6's fabric is significantly faster, so that inserting Partition Pins doesn't seem to impede the timing closure of our paltry 100MHz designs that much. The new PR tool chain seems to be able to work with the netlist of a plain ReconOS reference design without manual tweaking of clock buffer assignments or bus macro placement. This could lead to a much simplfied ReconOS tool chain. Putting the 'enable' modifications directly into the OSIF would also go some way towards simplifying the tool chain. I'll give it a try and keep you updated.

[reconos-devel] Partial reconfiguration - first success on ML605
Hi, I just wanted to notify you of some progress that's been made with the partial reconfiguration features of ReconOS. I've managed to create a set of partial bitstreams using the 12.3 tools (esp. PlanAhead) and the ReconOS tool chain. I've also been able to partially reconfigure single hardware threads manually via JTAG on the ML605. Things missing / to do: 1. Proper tool chain support: This will probably involve scripting PlanAhead to create the necessary configurations. I've been able to create a valid partially reconfigurable PlanAhead project using only the bitstreams generated by the ReconOS EAPR Makefile. Also, some renaming and cleanup of the "master" Makefile would be in order. Interestingly enough, the clocking magic we had to do with the old EAPR tool chain seems no longer necessary. 2. OSIF interface logic: Since the new PR tool flow does not use bus macros but instantiates the necessary Partition Pins automatically, we need to replicate some of the functionality of the former bus macros within the OSIF: - registers for all non-RAM (i.e. synchronous) signals to improve timing closure - enable signals for all outgoing signals (hardware thread to OSIF) to prevent accidental activity on reconfiguration 3. ICAP support for eCos: There is a new HWICAP IP core in EDK 12.3, which I hope to be faster and easier to use than the 9.02 versions. If there are any changes to the API we need to patch our hardware scheduling code accordingly. Also, a new reference design (ml605_light_pr) with the ICAP core should be created. Any comments, suggestions or questions are welcome. This list needs more traffic. :) Best regards - Enno ___ Reconos-devel_lists.reconos.de mailing list reconos-devel@lists.reconos.de https://ml01.ispgateway.de/mailman/listinfo/reconos-devel_lists.reconos.de
