18 Added a picture of the device pinouts to the specification. dgisselq 2960d 08h /s6soc/trunk/
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 2960d 08h /s6soc/trunk/
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 2960d 08h /s6soc/trunk/
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 2966d 02h /s6soc/trunk/
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.)
dgisselq 2966d 02h /s6soc/trunk/
13 Fixed a nasty parameter problem between toplevel and txuart. The UART
transmitter now both works (again), and properly generates the required
interrupts. This also finishes the fixes to the alternate toplevel file,
alttop.v, that should've been fixed in the last release.
dgisselq 2966d 02h /s6soc/trunk/
12 The UART and PWM audio now work. This includes the changes to make that
happen, as well as the source code for some UART and PWM demo programs.
dgisselq 2966d 23h /s6soc/trunk/
11 Runs on hardware now! Added proper pinouts, pipelined wishbone command
interface sufficient for loading the flash, a loader to load the flash,
and verified that they work.
dgisselq 2967d 21h /s6soc/trunk/
10 Added the capability to run ELF files natively, fully processing the ELF format. dgisselq 2967d 21h /s6soc/trunk/
9 Added pinout diagrams, based upon a (hopefully) final UCF file. dgisselq 2967d 21h /s6soc/trunk/
8 First pseudo-running version. The alternate configuration (not the main one)
has been initially tested. wbregs works for reading/writing registers,
so it is now possible to test the peripherals.
dgisselq 2972d 22h /s6soc/trunk/
7 Created/added an initial specification. Updated/corrected several copywrite
notices.
dgisselq 2973d 13h /s6soc/trunk/
6 Initial UCF modifications. Pin layout still isn't complete, but I'm starting
to work it.
dgisselq 2994d 08h /s6soc/trunk/
5 These two are my first attempt(s) at a secondary project file, one that can
run as an alternate to the main file but that gives more access to the hardware,
such as programming access to the flash.
dgisselq 2994d 08h /s6soc/trunk/
4 Lots of updates, as part of actually making this work on hardware. Not there
yet, so this is still pre-alpha.
dgisselq 2994d 08h /s6soc/trunk/
3 Updated date. dgisselq 2994d 08h /s6soc/trunk/
2 The initial check in--all the files that will make this SoC work. dgisselq 3005d 03h /s6soc/trunk/
1 The project and the structure was created root 3005d 04h /s6soc/trunk/
