41 Version 0.3 of the draft spec. This includes a description of the ZipOS,
the various files, how the pinouts support the PMods, and so forth. A *big*
rewrite.
dgisselq 2268d 14h /s6soc/
40 Added in internal document links, so you can click on contents items
(for example), and go directly to the referenced section.
dgisselq 2271d 14h /s6soc/
39 Fixes the doorbell light, so that it goes on and off properly now. dgisselq 2274d 07h /s6soc/
38 Updated the documentation. dgisselq 2274d 07h /s6soc/
37 Fixed the problem with the clock running too slow. dgisselq 2275d 05h /s6soc/
36 Many updates to the SPEC, although it's still by no means complete. dgisselq 2277d 05h /s6soc/
35 Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present.
dgisselq 2277d 05h /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 2277d 05h /s6soc/
33 Adjusted the defaults, so that more values have defined default values. dgisselq 2277d 06h /s6soc/
32 Removed an undefined value from o_lcd[2] setting. dgisselq 2277d 06h /s6soc/
31 Fixed a bug caught by Verilator. dgisselq 2277d 06h /s6soc/
30 Brings the CPU up to date with the rest of the ZipCPU distribution. dgisselq 2277d 06h /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 2277d 06h /s6soc/
28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2281d 17h /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 2281d 17h /s6soc/
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2281d 17h /s6soc/
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2281d 17h /s6soc/
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2281d 17h /s6soc/
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2281d 17h /s6soc/
22 Initial version of the ZipOS operating system construct(s). dgisselq 2285d 15h /s6soc/
