> 1) What sort of boot-loader did you use?
So far we did not use a boot-loader. We boot the system in one of the following
- for development by using an external debugger. In our case this is GDB. We
know that other external debuggers that support the PPC405 work, too (see
- for production
- we include a minimal boot stub in the FPGA bitstream. This initial boot
stub then boots the rest of the system
- we load the program into flash
- we use System ACE. System ACE is a companion chip that reads both
bitstream and program from a CompactFlash or MicroDrive, configures the FPGA,
loads the program into memory and boots the system. System ACE acts then as an
interface to the file system on the CompactFlash/MicroDrive.
- we are working on PPCBoot

GDB currently works with the Parallel-3 and Parallel-4 cable. Multilinx is not
supported and will never be (performance). Additional external debuggers may be
added as backends for GDB.
3rd party debuggers that we know to be working are (not an exclusive list)
- VisionProbe-II from Wind River
- VisionICE from Wind River
- Abatron BDI-2000

Watch out for announcements.
> 4) Will Xilinx be making a reference platform or evaluation board
Yes, this work is in progress but is not yet publicly announced. You can expect
an evaluation board to be available in Q3.

We are willing to give as much info as we can. But, since some of this has not
been announced yet I cannot go into all the details. Please also consider
getting into contact with your closest Xilinx representative or FAE to get more
information and to tell them about your projects.
