48 Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ...
dgisselq 3156d 09h /
47 Fixes the "NAN" clocks/second output, as well as making input timing come closer
to a realistic timing. (I actually don't know what timing the JTAG port is
providing, but ... the new timer is closer.)
dgisselq 3156d 09h /
46 This is a bug fix release--fixing the bug that kept dumpsdram.cpp/wbsdram.v
from working when long pipelined reads were interrupted by the necessity of
a pair of refresh cycles.
dgisselq 3156d 09h /
45 Minor cosmetic change, eliminates a warning in Xilinx's XISE but offers no
functional difference.
dgisselq 3160d 05h /
44 NELM parameter adjusted to reflect the maximum number of lines the compressed
scope can handle: 31, not 32.
dgisselq 3160d 05h /
43 Commentary changes only, no substance. dgisselq 3160d 05h /
42 Minor changes. dgisselq 3160d 05h /
41 Bug fix. This was preventing dumpsdram from accurately reading back what
had been written to the RAM earlier.
dgisselq 3160d 05h /
40 This adds to dumpsdram the capability to run over a port, such as with
busmaster_tb.
dgisselq 3161d 16h /
39 An attempt at a bugfix. We'll see if this works any better downstream. dgisselq 3163d 11h /
38 Updated to remove the build dependence upon ZipCPU. dgisselq 3163d 15h /
37 These fixes were necessary to get the SDRAM into a working simulation
capability. It is finally what it was supposed to be: cycle accurate. Sadly,
to do this, I did need to make a subtle change to rtl/wbsdram.v. (I was having
a problem with external input clocking in Verilator. This fixes it--but its
a Verilator only change--to rtl/wbsdram.v that is.)
dgisselq 3164d 09h /
36 A linker script, appropriate to the XuLA25-LX25 SoC. dgisselq 3164d 11h /
35 Updates the memory testing program to work successfully with the Gnu build
tools--particularly the GNU C-preprocessor from GCC and the GNU assembler from
Binutils.
dgisselq 3164d 11h /
34 Bug fix: This sets as a positive voltage bias (not negative) the maximum
value of 0x07fff, where as the negative maximum value of 0x08000 properly
(now) reflects nearly ground--as one would desire. (Last time around I had
these backwards.)
dgisselq 3168d 06h /
33 Oops -- the audio was wired audio first then the interrupt controller, not
the other way around. This adjusts regdefs to match what's on the chip.
dgisselq 3168d 07h /
32 Just noticed that the timer was fixed on this. This change adjusts the
timer to support audio at a user selectable rate.
dgisselq 3168d 07h /
31 A bug fix, although one that rearranges the bus. The first four I/O locations
have been adjusted. The new locations are reflected in wishbone.html. In
addition, the PWM and UART devices no longer create bus errors when accessed.
Finally, this version uses a `define XULA25 to determine whether or not to build
for the XuLA2-LX9 or the XuLA2-LX25. If defined, it will build for the
XuLA2-LX25. If not, for the XuLA2-LX9. The ideal location for this define
would be to place it into your Xilinx configuration, should you wish to build
for the LX25.
dgisselq 3168d 08h /
30 Bug fixes. In particular, this fixes a segmentation violation. dgisselq 3168d 12h /
29 This adds a vastly updated and superious ziprun capability to the repository.
ziprun now accepts ELF program files *only*, reads them, and places them onto
the board. This includes the ability, within the ELF file, of specifying
whether or not the data is sent to block ram, SD ram, or Flash, as well as
the ability of specifying the initial address. (Of course, that's a one time
thing--to always have the same initial address, set the address in
rtl/busmaster.v)
