the v4fx60 has two PPC405. Please make sure that both PPC405 are
connected to the jtagppc_cntrl in your MHS hardware project file. You
might want to compare your setup with the ML410 reference design
available at
The JTAG IR length of the v4fx60 is 14 (6 for the FPGA + 4 for each
PPC405, i.e. for the 4vfx60 it's 6+4+4=14)
Hi,
We are trying to generate a system ace file that will program an xf60
using Xilinx scripts,
(and even their impact GUI), using 8.1i, service pack 3 EDK.
Unfortunately, if we choose the ml410 board from Xilinx's genace.tcl
script
in their EDK/data/xmd directory, it errors with an invalid instruction
register length.
The irlength is listed as 14 in the xilinx script files. I looked and
googled and could
not find the irlength listed for that xf60 part in any literature.
Also, if we try to include the zImage.elf file, the script errors out.
Conversely, if we choose an ml403 board (and switch the project to
the xf12 chip),
we can combine the zImage.elf file and generate a system.ace file that
loads on an
ml403 board.
We can take the download.bit file that refuses to load when combined
into the system.ace,
and load it over the jtag port. It programs the xf60 just fine.
If we create an empty system.ace file, the system ace chip on our
board signals everything is ok,
but of course, the xilinx chip is not programmed. If we pull the
compact flash out of the board,
the system ace chip signals that is can't find the compact flash by
flashing the error light.
Has anyone on this list had any experience with this that could lead
us in a right direction? We've
tried about 10 different combinations so far with no luck.
thanks,
wade
