36 Many updates to the SPEC, although it's still by no means complete. dgisselq 2993d 11h /s6soc
35 Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present.
dgisselq 2993d 11h /s6soc
34 Adjusted this so that the "*.c" files are now archived. Also, I didn't
need archiving of python files, so that extension was removed as well.
dgisselq 2993d 11h /s6soc
33 Adjusted the defaults, so that more values have defined default values. dgisselq 2993d 11h /s6soc
32 Removed an undefined value from o_lcd[2] setting. dgisselq 2993d 11h /s6soc
31 Fixed a bug caught by Verilator. dgisselq 2993d 11h /s6soc
30 Brings the CPU up to date with the rest of the ZipCPU distribution. dgisselq 2993d 11h /s6soc
29 A first capability for setting time, dawn, and dusk values using the keypad.
At this point, I now have a minimal capability for actually accomplishing
the entire task. It's not very robust, but if you get lucky it'll work.
dgisselq 2993d 11h /s6soc
28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2997d 22h /s6soc
27 Added a bootloader capability so that pieces of the program may be immediately
loaded into RAM. Further, the custom linker script, cmodram.ld, has been
added to dispatch object files to either FLASH or RAM. Finally, for those
items that were headed to RAM, their support files have been split between
RAM and FLASH code: kernel.c/ksetup.c, syspipe.c/pipesetup.c, etc.
dgisselq 2997d 22h /s6soc
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2997d 22h /s6soc
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2997d 22h /s6soc
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2997d 23h /s6soc
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2997d 23h /s6soc
22 Initial version of the ZipOS operating system construct(s). dgisselq 3001d 21h /s6soc
21 Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock.
dgisselq 3001d 21h /s6soc
20 This linker description file acknowledges a .fixdata section which can be
used for debug data upon startup. This allows a startup function to write
all registers out, without destroying them or modifying them on the way.
dgisselq 3001d 21h /s6soc
19 Addition of dumpuart.cpp to dump the UART transactions to a FILE (method of
debugging the board). FLASHDRVR and ZIPLOAD were also updated to handle
loading ELF files where the code is longer than a single block.
dgisselq 3001d 21h /s6soc
18 Added a picture of the device pinouts to the specification. dgisselq 3001d 21h /s6soc
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 3001d 22h /s6soc
