195 Switched to using the UART over usb for the console port. davidgb 611d 23h /System09/
194 Finally have a working board. davidgb 611d 23h /System09/
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 612d 03h /System09/
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 612d 03h /System09/
191 check in file so that you do not need to generate it when running ISE in gui davidgb 613d 00h /System09/
190 check in file so that you do not need to generate it when running ISE in gui davidgb 613d 00h /System09/
189 Remove unused file. Created by ISE gui. davidgb 618d 18h /System09/
188 update options to match what the ISE gui does davidgb 618d 18h /System09/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 618d 23h /System09/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 619d 02h /System09/
185 Reverted back to the single-step version - something was broken davidgb 619d 04h /System09/
184 update files to correctly produce flex9ram.vhd davidgb 619d 04h /System09/
183 update file extensions davidgb 619d 04h /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 619d 04h /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 619d 04h /System09/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 619d 05h /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 619d 05h /System09/
178 work on constraints file davidgb 619d 16h /System09/
177 work on zybo port davidgb 619d 17h /System09/
176 Don't delete system09_impact.cmd on 'clean' davidgb 619d 18h /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 619d 18h /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 619d 22h /System09/
173 Add another 16k BRAM for 56K total memory davidgb 621d 17h /System09/
172 Add 16k RAM davidgb 621d 17h /System09/
171 remove old Xess files davidgb 621d 22h /System09/
170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.
davidgb 621d 23h /System09/
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 622d 04h /System09/
168 Added more pinloc info. Switched RS-232 to use PMOD connector for more h/w debug visibility. davidgb 622d 04h /System09/
167 Update MAP_FLAGS for z20. Update UCF to have Pmod JC for the RS-232 Pmod davidgb 622d 17h /System09/
166 hack some pin locs. davidgb 622d 17h /System09/
