204 patched up ram for zybo use davidgb 1158d 05h /System09/
203 Added a parameterized ram model. davidgb 1158d 05h /System09/
202 Updated Zybo design to reintroduce VDU8 driving the PmodVGA on pmod connectors JC+JD.
This version also uses PmodUSBUART on JE. To use PmodRS232 you must edit the .ucf file and select the appropriate pin LOCs.		 davidgb 1158d 06h /System09/
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1165d 00h /System09/
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1171d 22h /System09/
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1172d 23h /System09/
198 Update UCF file to select Pmod pinout compatible with the PmodUSBUART.
To use, make sure PmodUSBUART has JP1 as "LCL". Connect the usb to the uart and open the terminal program. Test the transmission via the LED on the Pmod. Then (carefully) plug into Pmod port on Zybo.		 davidgb 1173d 00h /System09/
197 Updates from John Kent:
-- 4.5 John Kent 2012-02-04 Re-arranged Rx & Tx Baud clock edge detect.
-- 4.6 John Kent 3021-01-30 Double sample RxC, TxC, and RxD with cpu_clk
-- for 125MHz Clock on Zybo Z7 board.		 davidgb 1179d 21h /System09/
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1179d 21h /System09/
195 Switched to using the UART over usb for the console port. davidgb 1179d 22h /System09/
194 Finally have a working board. davidgb 1179d 22h /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 1180d 02h /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 1180d 02h /System09/
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1180d 23h /System09/
190 check in file so that you do not need to generate it when running ISE in gui davidgb 1180d 23h /System09/
189 Remove unused file. Created by ISE gui. davidgb 1186d 17h /System09/
188 update options to match what the ISE gui does davidgb 1186d 17h /System09/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1186d 22h /System09/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1187d 01h /System09/
185 Reverted back to the single-step version - something was broken davidgb 1187d 03h /System09/
184 update files to correctly produce flex9ram.vhd davidgb 1187d 03h /System09/
183 update file extensions davidgb 1187d 03h /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 1187d 03h /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 1187d 03h /System09/
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1187d 04h /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 1187d 04h /System09/
178 work on constraints file davidgb 1187d 15h /System09/
177 work on zybo port davidgb 1187d 16h /System09/
176 Don't delete system09_impact.cmd on 'clean' davidgb 1187d 17h /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 1187d 17h /System09/
