43 Most recent build date. dgisselq 2449d 02h /s6soc/
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 2449d 02h /s6soc/
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 2449d 02h /s6soc/
40 Added in internal document links, so you can click on contents items
(for example), and go directly to the referenced section.
dgisselq 2452d 02h /s6soc/
39 Fixes the doorbell light, so that it goes on and off properly now. dgisselq 2454d 19h /s6soc/
38 Updated the documentation. dgisselq 2454d 19h /s6soc/
37 Fixed the problem with the clock running too slow. dgisselq 2455d 17h /s6soc/
36 Many updates to the SPEC, although it's still by no means complete. dgisselq 2457d 17h /s6soc/
35 Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present.
dgisselq 2457d 17h /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 2457d 17h /s6soc/
33 Adjusted the defaults, so that more values have defined default values. dgisselq 2457d 18h /s6soc/
32 Removed an undefined value from o_lcd[2] setting. dgisselq 2457d 18h /s6soc/
31 Fixed a bug caught by Verilator. dgisselq 2457d 18h /s6soc/
30 Brings the CPU up to date with the rest of the ZipCPU distribution. dgisselq 2457d 18h /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 2457d 18h /s6soc/
28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2462d 05h /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 2462d 05h /s6soc/
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2462d 05h /s6soc/
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2462d 05h /s6soc/
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2462d 05h /s6soc/
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2462d 05h /s6soc/
22 Initial version of the ZipOS operating system construct(s). dgisselq 2466d 03h /s6soc/
21 Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock.
dgisselq 2466d 04h /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 2466d 04h /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 2466d 04h /s6soc/
18 Added a picture of the device pinouts to the specification. dgisselq 2466d 04h /s6soc/
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 2466d 04h /s6soc/
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 2466d 04h /s6soc/
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.
dgisselq 2471d 22h /s6soc/
14 Modified the loader so that it will load even if there are RAM variables
in the load, just as long as they aren't anything but zero. (The startup code,
however, doesn't clear memory to match--so be sure to initialize all variables.)
