Made adjustments so that the s/w now matches it's specification document,
as it should've been. |

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). |

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. |

Added in internal document links, so you can click on contents items
(for example), and go directly to the referenced section. |

Fixes the doorbell light, so that it goes on and off properly now. |

Fixed the problem with the clock running too slow. |

Many updates to the SPEC, although it's still by no means complete. |

Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present. |

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. |

Adjusted the defaults, so that more values have defined default values. |

Removed an undefined value from o_lcd[2] setting. |

Fixed a bug caught by Verilator. |

Brings the CPU up to date with the rest of the ZipCPU distribution. |

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. |

Fixed a small lint bug associated with the scope vs the compressed scope. |

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. |

Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability. |

Converted timer B to be a non-reloadable watchdog timer. |

Made the ziptimer autoreload feature a parameter (dis)abled option. |

Fixed a bug which caused every instruction to be loaded/prefetched twice. |

Initial version of the ZipOS operating system construct(s). |

3270d 05h |
/s6soc/ |

Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock. |

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. |

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 |
3270d 06h |
/s6soc/ |
| 18 |
Added a picture of the device pinouts to the specification. |
dgisselq |
3270d 06h |

Modifications necessary to find some bugs, and to load the flash with an ELF
file. |

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 |
3270d 06h |
/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. |
