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 2459d 21h /
18 Added a picture of the device pinouts to the specification. dgisselq 2459d 21h /
17 Modifications necessary to find some bugs, and to load the flash with an ELF
file.
dgisselq 2459d 21h /
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 2459d 21h /
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 2465d 14h /
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 2465d 14h /
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 2465d 14h /
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 2466d 12h /
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 2467d 10h /
10 Added the capability to run ELF files natively, fully processing the ELF format. dgisselq 2467d 10h /
