113 Lots of updates, mostly focused on getting the XuLA board and CPU able to pass
a comprehensive test suite. At this point, everything passes and logic usage
is down even. Among the few changes includes the "break" bit in the uCC
register, used to indicate a switch to supervisor mode occurred as a result
of a user break, and the ability for the supervisor to clear the instruction
cache.
dgisselq 3047d 12h /xulalx25soc/trunk/sw
111 Added some debug support programs to the repository. dgisselq 3055d 10h /xulalx25soc/trunk/sw
110 Fixed a problem whereby block RAM would be declared as a bus error on the
stack, even if the data was valid.
dgisselq 3055d 15h /xulalx25soc/trunk/sw
109 This continues the updates to the wishbone-uart conversion. It fixes several
bugs within wbuexec, and pipelines the compression scheme. Further, the
read codeword was adjusted so that a read of 8 can be requested with six-bits,
rather than requiring 12. Likewise, the dependence upon the read of 8 on
incrementing the address pointer has been removed. All told, the design
builds for a 200MHz Artix-7, and it has been tested with the CMod-S6. (Writing
flash seems to be one of the most comprehensive tests ...)
dgisselq 3055d 19h /xulalx25soc/trunk/sw
105 Mostly cosmetic changes. The Makefile now builds a couple more programs,
the documentation is better, etc.
dgisselq 3056d 06h /xulalx25soc/trunk/sw
104 Updates to the flash driver drawn from the S6SoC project. dgisselq 3056d 06h /xulalx25soc/trunk/sw
103 Added a SDSPI scope, and defined which of the four scopes it points to.
(It uses the configuration scopes position, if the configuration scope isn't
defined.)
dgisselq 3056d 06h /xulalx25soc/trunk/sw
93 Oops -- missed adjusting the copyright. dgisselq 3079d 10h /xulalx25soc/trunk/sw
92 Fixes the problem whereby the master counters show when the user counters should
be showing and vice versa. Now the master counters show by default, together
with their correct labels. User counters are still available by pressing
'u' in the debugger, and the master counter display may be returned to by
pressing 'm' in the debugger.
dgisselq 3079d 10h /xulalx25soc/trunk/sw
91 Fixes bugs associated with an overflow of write acknowledgements in the
receiver. This helps keep our accesses aligned.
dgisselq 3079d 10h /xulalx25soc/trunk/sw
78 Comments out the line that caused a compiler warning--setting an unused
variable. Code should be better as a result.
dgisselq 3085d 06h /xulalx25soc/trunk/sw
77 Adds register names and values for the SD card interface. dgisselq 3085d 06h /xulalx25soc/trunk/sw
76 Now tries to avoid reading from the stack if the stack addresses are already
known to be bad. That way, the debugger tries to preserve any bus error address
already on the buserr device.
dgisselq 3085d 06h /xulalx25soc/trunk/sw
53 Added a touch of error checking. dgisselq 3133d 07h /xulalx25soc/trunk/sw
49 Added some documentation to make the read and write calls easier to understand. dgisselq 3161d 09h /xulalx25soc/trunk/sw
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 3163d 10h /xulalx25soc/trunk/sw
42 Minor changes. dgisselq 3167d 06h /xulalx25soc/trunk/sw
41 Bug fix. This was preventing dumpsdram from accurately reading back what
had been written to the RAM earlier.
dgisselq 3167d 06h /xulalx25soc/trunk/sw
40 This adds to dumpsdram the capability to run over a port, such as with
busmaster_tb.
dgisselq 3168d 17h /xulalx25soc/trunk/sw
38 Updated to remove the build dependence upon ZipCPU. dgisselq 3170d 16h /xulalx25soc/trunk/sw
