44 Made adjustments so that the s/w now matches it's specification document,
as it should've been.
dgisselq 2891d 05h /
43 Most recent build date. dgisselq 2891d 05h /
42 Adjusted the timer to support both auto-reloading and non-auto-reloading
functionality--in order to save space. Hence the watch-dog timer, which doesn't
need any reloading functionality, doesn't get it (anymore).
dgisselq 2891d 05h /
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 2891d 05h /
40 Added in internal document links, so you can click on contents items
(for example), and go directly to the referenced section.
dgisselq 2894d 06h /
39 Fixes the doorbell light, so that it goes on and off properly now. dgisselq 2896d 23h /
38 Updated the documentation. dgisselq 2896d 23h /
37 Fixed the problem with the clock running too slow. dgisselq 2897d 20h /
36 Many updates to the SPEC, although it's still by no means complete. dgisselq 2899d 21h /
35 Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present.
dgisselq 2899d 21h /
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 2899d 21h /
33 Adjusted the defaults, so that more values have defined default values. dgisselq 2899d 21h /
32 Removed an undefined value from o_lcd[2] setting. dgisselq 2899d 21h /
31 Fixed a bug caught by Verilator. dgisselq 2899d 21h /
30 Brings the CPU up to date with the rest of the ZipCPU distribution. dgisselq 2899d 21h /
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 2899d 21h /
28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2904d 08h /
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 2904d 08h /
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2904d 08h /
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2904d 08h /
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2904d 09h /
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2904d 09h /
22 Initial version of the ZipOS operating system construct(s). dgisselq 2908d 07h /
21 Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock.
dgisselq 2908d 07h /
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 2908d 07h /
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 2908d 07h /
18 Added a picture of the device pinouts to the specification. dgisselq 2908d 08h /
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 2908d 08h /
16 Bug fix. This release fixes several bugs associated with transitioning from
user mode to supervisor mode while running from flash memory. This also
rewires TIMER-B into a watch-dog timer, and adjusts the LED's to be an
indicator of interrupts and whether or not the CPU has stalled or not as well.
dgisselq 2908d 08h /
15 Adds a new program and a new device: doorbell2 and the PmodCLS display. This
also includes a real-time clock simulator--since we couldn't fit it on the
board.
