28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2463d 04h /s6soc/trunk/
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 2463d 04h /s6soc/trunk/
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2463d 04h /s6soc/trunk/
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2463d 04h /s6soc/trunk/
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2463d 04h /s6soc/trunk/
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2463d 04h /s6soc/trunk/
22 Initial version of the ZipOS operating system construct(s). dgisselq 2467d 03h /s6soc/trunk/
21 Adds two device drivers: one for the SPI display, and another for the pseudo
device that simulates the Real-Time Clock.
dgisselq 2467d 03h /s6soc/trunk/
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 2467d 03h /s6soc/trunk/
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 2467d 03h /s6soc/trunk/
18 Added a picture of the device pinouts to the specification. dgisselq 2467d 03h /s6soc/trunk/
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 2467d 04h /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 2467d 04h /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 2472d 21h /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 2472d 21h /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 2472d 21h /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 2473d 19h /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 2474d 17h /s6soc/trunk/
10 Added the capability to run ELF files natively, fully processing the ELF format. dgisselq 2474d 17h /s6soc/trunk/
9 Added pinout diagrams, based upon a (hopefully) final UCF file. dgisselq 2474d 17h /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 2479d 17h /s6soc/trunk/
7 Created/added an initial specification. Updated/corrected several copywrite
notices.
dgisselq 2480d 08h /s6soc/trunk/
6 Initial UCF modifications. Pin layout still isn't complete, but I'm starting
to work it.
dgisselq 2501d 03h /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 2501d 03h /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 2501d 03h /s6soc/trunk/
3 Updated date. dgisselq 2501d 03h /s6soc/trunk/
2 The initial check in--all the files that will make this SoC work. dgisselq 2511d 22h /s6soc/trunk/
1 The project and the structure was created root 2511d 23h /s6soc/trunk/
