I have listed all the "special" stuff, you probably have some of it already. * The latest UrJTAG, with Michael Walle's patches merged and FJMEM for ÂSpartan-6. These patches add free software support for configuring Âthe FPGA on our boards and reprogramming the flash. The patches have Âbeen merged upstream into UrJTAG. Michael: do we need anything Âspecial for out-of-the-box FJMEM support, or is it included in the Âstock UrJTAG installation? * Michael's modified OpenOCD [1], not merged upstream yet. This enables Âin-circuit JTAG debugging of the Milkymist SoC. * Michael's modified QEMU [2] with LM32 and Milkymist support, not Âmerged upstream yet. * lm32-elf toolchain (including GCC, Binutils and GDB). I recommend GCC Â4.5.1 that has the LM32 support included and a reasonable amount of Âbugs. No patches are needed for these tools, they work as released by Âthe FSF. Newlib is not needed for this toolchain, which makes this Âitem independent of the licensing discussion you had lately [2]. This Âtoolchain is used for building the Milkymist BIOS, the demo renderer Âand the experimental uClinux kernel. All those come with their own Âbuilt-in libc. * Scilab [4], used for building the demo renderer. The GUI is not Âneeded for our purposes. * Lemon parser generator [5] (you may already have this one). * RE2C [6] (same comment). * An easy to configure/pre-installed TFTP server (same comment) for Ânetbooting the board. * lm32-rtems toolchain, which uses newlib so I hope the licensing Âdiscussions [3] can be settled soon. Again, I recommend the GCC 4.5.1 Âbased toolchain. There are already Fedora RPM packages available at Âthe RTEMS FTP [7] (browse around for SRPMS and other versions) and Âyou can see [8] for generic build instructions. * An installation of the modified RTEMS [9] (not fully merged upstream Âyet) built for Milkymist. * The flterm serial terminal and firmware download program [10]. * libGD [11] and its development headers (you most probably already have Âthis) that we use in the software build process and through VPI in Âsome Verilog test benches that process images. * FTDI libraries [12] (probably already included) for using Yanjun Luo's ÂMilkymist One JTAG adapter [13] with UrJTAG. * Native (x86) clang (LLVM), used for building some host-side tools in Âthe build process. * SRecord [14]. * xxd hexdump command. Phew! I hope I have not forgotten anything. Anyway, I'll be happy to install FEL and try to build Milkymist stuff and use the JTAG tools to check that nothing is missing :) If all of this sounds too much for you, I can prioritize the list. There are no FPGA tools (except maybe the JTAG programmer), those are proprietary and non-redistributable and there are no serious free equivalents. You already have the Verilog simulators that we use (Icarus Verilog + GPL Cver) and GTKWave. Cheers, S.
