187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 675d 13h /System09/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 675d 16h /System09/
185 Reverted back to the single-step version - something was broken davidgb 675d 18h /System09/
184 update files to correctly produce flex9ram.vhd davidgb 675d 18h /System09/
183 update file extensions davidgb 675d 18h /System09/
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 675d 18h /System09/
181 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 675d 18h /System09/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 675d 19h /System09/
179 Zybo port done to the same point as the Atlys port. The hardware appears to work but the ACIA is not communicating properly. davidgb 675d 19h /System09/
178 work on constraints file davidgb 676d 06h /System09/
177 work on zybo port davidgb 676d 06h /System09/
176 Don't delete system09_impact.cmd on 'clean' davidgb 676d 08h /System09/
175 Corrected RS-232 pin connections. Cleaned up code. Removed debug code.
System boots but the baud clock must be wrong - get garbage on hyperterm.
davidgb 676d 08h /System09/
174 Added button debounce. Single-step button. multiplex LED to show nibbles of addr and data for debug. Confirmed that CPU is reading from sys09swt.vhd SBug ROM correctly. Still need to debug ACIA output. davidgb 676d 11h /System09/
173 Add another 16k BRAM for 56K total memory davidgb 678d 07h /System09/
172 Add 16k RAM davidgb 678d 07h /System09/
171 remove old Xess files davidgb 678d 12h /System09/
170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.
davidgb 678d 12h /System09/
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 678d 18h /System09/
168 Added more pinloc info. Switched RS-232 to use PMOD connector for more h/w debug visibility. davidgb 678d 18h /System09/
