Hi all,
I'm poking around the USRP2's CPLD, the XC9572, mainly just to
understand exactly how the U2 boots, and so looking for the Verilog
source code that goes into the CPLD. I find
usrp2/fpga/boot_cpld/boot_cpld.v, but this file has a comment that it is
"only for u2_rev2," and I'm using u2_rev3 like most others.
This comment is old, and it meant "not for the rev 1". So it works with
the rev2 (which was never sold) and the rev 3 and rev 4. boot_cpld.v is
the top level file, and it includes some of the files from
opencores/spi_boot
usrp2/fpga/models/cpld_model.v looks promising too; any hints?
That is a file used to model the CPLD in order to do simulations of the
FPGA. It is not compiled into the design itself.
