49 Added some documentation to make the read and write calls easier to understand. dgisselq 2977d 14h /xulalx25soc/
48 Cleaned up the documentation a touch. It no longer reads like the bugs I used
to debug are still being debugged ...
dgisselq 2979d 15h /xulalx25soc/
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 2979d 15h /xulalx25soc/
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 2979d 15h /xulalx25soc/
45 Minor cosmetic change, eliminates a warning in Xilinx's XISE but offers no
functional difference.
dgisselq 2983d 11h /xulalx25soc/
44 NELM parameter adjusted to reflect the maximum number of lines the compressed
scope can handle: 31, not 32.
dgisselq 2983d 11h /xulalx25soc/
43 Commentary changes only, no substance. dgisselq 2983d 11h /xulalx25soc/
42 Minor changes. dgisselq 2983d 11h /xulalx25soc/
41 Bug fix. This was preventing dumpsdram from accurately reading back what
had been written to the RAM earlier.
dgisselq 2983d 11h /xulalx25soc/
40 This adds to dumpsdram the capability to run over a port, such as with
busmaster_tb.
dgisselq 2984d 22h /xulalx25soc/
39 An attempt at a bugfix. We'll see if this works any better downstream. dgisselq 2986d 17h /xulalx25soc/
38 Updated to remove the build dependence upon ZipCPU. dgisselq 2986d 21h /xulalx25soc/
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 2987d 15h /xulalx25soc/
36 A linker script, appropriate to the XuLA25-LX25 SoC. dgisselq 2987d 17h /xulalx25soc/
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 2987d 17h /xulalx25soc/
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 2991d 12h /xulalx25soc/
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 2991d 14h /xulalx25soc/
32 Just noticed that the timer was fixed on this. This change adjusts the
timer to support audio at a user selectable rate.
dgisselq 2991d 14h /xulalx25soc/
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 2991d 14h /xulalx25soc/
30 Bug fixes. In particular, this fixes a segmentation violation. dgisselq 2991d 18h /xulalx25soc/
