249 Cleaned up bootloader. ja_rd 4256d 16h /ion/trunk/src
248 Fixed silly typo in sd bootloader. ja_rd 4256d 16h /ion/trunk/src
247 Added a precompiled binary of 'Adventure' ready to be bootloaded from an SD card. ja_rd 4256d 16h /ion/trunk/src
246 Added a SD-card bootloader demo.
Now we can load binaries from the DE-1 board SD interface.
This saves time because we no longer have to resynthesize the core to try new software. AND we can now run from 16-bit RAM, which should be faster than 8-bit flash...		 ja_rd 4256d 16h /ion/trunk/src
245 Modified 'Adventure' demo: added a make target to build a 'bootloadable' version of the binary.
The new binary ('code.bin') can be loaded and run from RAM at address 0x0 using the sdboot demo bootloader.		 ja_rd 4256d 16h /ion/trunk/src
244 New link script that puts everything on XRAM (16-bit SRAM on the DE-1 board).
Programs linked with this script will have to be 'bootloaded' on RAM.		 ja_rd 4256d 16h /ion/trunk/src
243 Added a port of ElmChan's FatFS library for the DE-1 board.
Uses bit-banged SPI interface so it should be trivially easy to port to other boards.		 ja_rd 4256d 17h /ion/trunk/src
238 BUG FIX: C startup code that copied initialized data to data section was wrong when initialized data was not a multiple of 4 bytes. ja_rd 4256d 22h /ion/trunk/src
236 Added macros to SoC header file for easy access to GPIO registers ja_rd 4257d 18h /ion/trunk/src
229 Code samples updated to use new VHDL config packages and new SoC (UART). ja_rd 4404d 23h /ion/trunk/src
213 Memory test application updated -- added extra-simple D-Cache test.
The new test is a row of back-to-back I/O reads and writes.
This test triggers a bug in the cache that has been already fixed.		 ja_rd 4415d 22h /ion/trunk/src
203 Opcode test program prepared to test interrupts
(by using special simulated hardware in the test bench)
More changes to come, this is just the first commit of many		 ja_rd 4729d 17h /ion/trunk/src
197 Updated readme stuff for the code samples ja_rd 4731d 08h /ion/trunk/src
196 Marked old TB template as obsolete.
I'm not comfortable removing it yet. Silly, that.		 ja_rd 4731d 08h /ion/trunk/src
195 Template for TB parameter package.
This file is 'filled in' with actual info by a python script.		 ja_rd 4731d 08h /ion/trunk/src
193 Major test bench reorganization:
1.- TB now uses same object code as synthesizable demo.
2.- TB now simulates full MPU system.
3.- Console logging moved to TB package.
4.- Code sample makefiles and modelsim script updated accordingly.		 ja_rd 4731d 08h /ion/trunk/src
192 Code ROM template for MCU
Contains bootstrap object code to be placed on BRAM		 ja_rd 4735d 18h /ion/trunk/src
191 Separated object code stuff from mcu entity
Object code related stuff now lives in separate file
Makefiles for code samples updated accordingly
Old mcu template deprecated but still in place		 ja_rd 4735d 18h /ion/trunk/src
190 VHDL object code builder script updated
Now can insert project name into target file		 ja_rd 4735d 18h /ion/trunk/src
189 fixed opcode test makefile: adapted to new common makefile ja_rd 4743d 16h /ion/trunk/src
185 FIX: committed forgotten source file for 'memtest' demo...
Updated memtest makefile		 ja_rd 4770d 06h /ion/trunk/src
184 Updated some application makefiles to make use of common makefile ja_rd 4770d 06h /ion/trunk/src
183 Updated comments and readme file for code samples ja_rd 4771d 22h /ion/trunk/src
182 Updated makefiles for Hello and Adventure
Removed old dependencies in Adventure demo		 ja_rd 4771d 22h /ion/trunk/src
181 Bug fix: left out a link script in last commit ja_rd 4771d 22h /ion/trunk/src
180 Removed old support code
Bits of it may yet reappear as part of the new support library		 ja_rd 4772d 09h /ion/trunk/src
179 'Adventure' demo updated, removed dependencies to old support code ja_rd 4772d 09h /ion/trunk/src
178 Added FP math support to support library
Uses code lifted from old version of GNU libc, no adaptation needed
NEEDS testing!		 ja_rd 4772d 09h /ion/trunk/src
177 Modified 'Adventure' demo to use new support code ja_rd 4772d 09h /ion/trunk/src
176 Modified 'hello' to use new support code
NOTE: the 'OPCODE EMULATOR' mentioned below is the TRAP HANDLER
The SW opcode emulation has been working for months		 ja_rd 4772d 09h /ion/trunk/src
