195 Switched to using the UART over usb for the console port. davidgb 1227d 16h /System09/trunk
194 Finally have a working board. davidgb 1227d 16h /System09/trunk
193 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. Also fixed the 32k addressing davidgb 1227d 20h /System09/trunk
192 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. davidgb 1227d 20h /System09/trunk
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1228d 17h /System09/trunk
190 check in file so that you do not need to generate it when running ISE in gui davidgb 1228d 17h /System09/trunk
189 Remove unused file. Created by ISE gui. davidgb 1234d 11h /System09/trunk
188 update options to match what the ISE gui does davidgb 1234d 11h /System09/trunk
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1234d 16h /System09/trunk
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1234d 19h /System09/trunk
185 Reverted back to the single-step version - something was broken davidgb 1234d 20h /System09/trunk
184 update files to correctly produce flex9ram.vhd davidgb 1234d 21h /System09/trunk
183 update file extensions davidgb 1234d 21h /System09/trunk
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1234d 21h /System09/trunk
181 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1234d 21h /System09/trunk
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1234d 22h /System09/trunk
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 1234d 22h /System09/trunk
178 work on constraints file davidgb 1235d 09h /System09/trunk
177 work on zybo port davidgb 1235d 09h /System09/trunk
176 Don't delete system09_impact.cmd on 'clean' davidgb 1235d 11h /System09/trunk
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 1235d 11h /System09/trunk
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 1235d 14h /System09/trunk
173 Add another 16k BRAM for 56K total memory davidgb 1237d 10h /System09/trunk
172 Add 16k RAM davidgb 1237d 10h /System09/trunk
171 remove old Xess files davidgb 1237d 15h /System09/trunk
170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.		 davidgb 1237d 15h /System09/trunk
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 1237d 21h /System09/trunk
168 Added more pinloc info. Switched RS-232 to use PMOD connector for more h/w debug visibility. davidgb 1237d 21h /System09/trunk
167 Update MAP_FLAGS for z20. Update UCF to have Pmod JC for the RS-232 Pmod davidgb 1238d 10h /System09/trunk
166 hack some pin locs. davidgb 1238d 10h /System09/trunk
